[Update on manual bronchial clearance techniques (adults and adolescents)]. / Mise au point sur les techniques manuelles de désencombrement bronchique (adultes et adolescents).

In adults and teenagers, airway clearance physiotherapy techniques (ACPT) are various and numerous. However, they for still awaiting scientific validation. Among ACPTs, Slow Expiration with the Glottis Opened in the Lateral Posture (ELTGOL), Autogenic Drainage (DA), and Active Cycling Breathing Technique (ACBT) present a Grade B level of evidence with weak recommendations. Even though these maneuvers are widely applied, precise description of chest physiotherapy (CP) is largely absent from the scientific literature; it is difficult to standardize its implementation and reproduce the results; scientific validation and faithful execution of the techniques are consequently problematic. In this paper, the authors aim to depict each of the three CP techniques as precisely as possible; with this in mind, graphic modeling of the different respiratory exercises is presented in such a way that they can be easily learned, applied and reproduced by physiotherapists.

Conventional chest physiotherapy compared to other airway clearance techniques for cystic fibrosis.

BACKGROUND: Cystic fibrosis (CF) is an inherited life-limiting disorder. Over time persistent infection and inflammation within the lungs contribute to severe airway damage and loss of respiratory function. Chest physiotherapy, or airway clearance techniques (ACTs), are integral in removing airway secretions and initiated shortly after CF diagnosis. Conventional chest physiotherapy (CCPT) generally requires assistance, while alternative ACTs can be self-administered, facilitating independence and flexibility. This is an updated review. OBJECTIVES: To evaluate the effectiveness (in terms of respiratory function, respiratory exacerbations, exercise capacity) and acceptability (in terms of individual preference, adherence, quality of life) of CCPT for people with CF compared to alternative ACTs. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search was 26 June 2022. SELECTION CRITERIA: We included randomised or quasi-randomised controlled trials (including cross-over design) lasting at least seven days and comparing CCPT with alternative ACTs in people with CF. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were 1. pulmonary function tests and 2. number of respiratory exacerbations per year. Our secondary outcomes were 3. quality of life, 4. adherence to therapy, 5. cost-benefit analysis, 6. objective change in exercise capacity, 7. additional lung function tests, 8. ventilation scanning, 9. blood oxygen levels, 10. nutritional status, 11. mortality, 12. mucus transport rate and 13. mucus wet or dry weight. We reported outcomes as short-term (seven to 20 days), medium-term (more than 20 days to up to one year) and long-term (over one year). MAIN RESULTS: We included 21 studies (778 participants) comprising seven short-term, eight medium-term and six long-term studies. Studies were conducted in the USA (10), Canada (five), Australia (two), the UK (two), Denmark (one) and Italy (one) with a median of 23 participants per study (range 13 to 166). Participant ages ranged from newborns to 45 years; most studies only recruited children and young people. Sixteen studies reported the sex of participants (375 males; 296 females). Most studies compared modifications of CCPT with a single comparator, but two studies compared three interventions and another compared four interventions. The interventions varied in the duration of treatments, times per day and periods of comparison making meta-analysis challenging. All evidence was very low certainty. Nineteen studies reported the primary outcomes forced expiratory volume in one second (FEV1)and forced vital capacity (FVC), and found no difference in change from baseline in FEV1 % predicted or rate of decline between groups for either measure. Most studies suggested equivalence between CCPT and alternative ACTs, including positive expiratory pressure (PEP), extrapulmonary mechanical percussion, active cycle of breathing technique (ACBT), oscillating PEP devices (O-PEP), autogenic drainage (AD) and exercise. Where single studies suggested superiority of one ACT, these findings were not corroborated in similar studies; pooled data generally concluded that effects of CCPT were comparable to those of alternative ACTs. CCPT versus PEP We are uncertain whether CCPT improves lung function or has an impact on the number of respiratory exacerbations per year compared with PEP (both very low-certainty evidence). There were no analysable data for our secondary outcomes, but many studies provided favourable narrative reports on the independence achieved with PEP mask therapy. CCPT versus extrapulmonary mechanical percussion We are uncertain whether CCPT improves lung function compared with extrapulmonary mechanical percussions (very low-certainty evidence). The annual rate of decline in average forced expiratory flow between 25% and 75% of FVC (FEF25-75) was greater with high-frequency chest compression compared to CCPT in medium- to long-term studies, but there was no difference in any other outcome. CCPT versus ACBT We are uncertain whether CCPT improves lung function compared to ACBT (very low-certainty evidence). Annual decline in FEF25-75 was worse in participants using the FET component of ACBT only (mean difference (MD) 6.00, 95% confidence interval (CI) 0.55 to 11.45; 1 study, 63 participants; very low-certainty evidence). One short-term study reported that directed coughing was as effective as CCPT for all lung function outcomes, but with no analysable data. One study found no difference in hospital admissions and days in hospital for exacerbations. CCPT versus O-PEP We are uncertain whether CCPT improves lung function compared to O-PEP devices (Flutter device and intrapulmonary percussive ventilation); however, only one study provided analysable data (very low-certainty evidence). No study reported data for number of exacerbations. There was no difference in results for number of days in hospital for an exacerbation, number of hospital admissions and number of days of intravenous antibiotics; this was also true for other secondary outcomes. CCPT versus AD We are uncertain whether CCPT improves lung function compared to AD (very low-certainty evidence). No studies reported the number of exacerbations per year; however, one study reported more hospital admissions for exacerbations in the CCPT group (MD 0.24, 95% CI 0.06 to 0.42; 33 participants). One study provided a narrative report of a preference for AD. CCPT versus exercise We are uncertain whether CCPT improves lung function compared to exercise (very low-certainty evidence). Analysis of original data from one study demonstrated a higher FEV1 % predicted (MD 7.05, 95% CI 3.15 to 10.95; P = 0.0004), FVC (MD 7.83, 95% CI 2.48 to 13.18; P = 0.004) and FEF25-75 (MD 7.05, 95% CI 3.15 to 10.95; P = 0.0004) in the CCPT group; however, the study reported no difference between groups (likely because the original analysis accounted for baseline differences). AUTHORS' CONCLUSIONS: We are uncertain whether CCPT has a more positive impact on respiratory function, respiratory exacerbations, individual preference, adherence, quality of life, exercise capacity and other outcomes when compared to alternative ACTs as the certainty of the evidence is very low. There was no advantage in respiratory function of CCPT over alternative ACTs, but this may reflect insufficient evidence rather than real equivalence. Narrative reports indicated that participants prefer self-administered ACTs. This review is limited by a paucity of well-designed, adequately powered, long-term studies. This review cannot yet recommend any single ACT above others; physiotherapists and people with CF may wish to try different ACTs until they find an ACT that suits them best.

Effectiveness of Autogenic Drainage in Improving Pulmonary Function in Patients with Cystic Fibrosis.

The use of autogenic drainage (AD) in patients with cystic fibrosis (CF) has been officially approved; therefore, the purpose of this study was to compare the efficiency of the leading therapeutic techniques based on AD in patients with CF; Among patients with CF assessments were made of spirometric parameters, percent blood oxygen saturation, and the general feeling of the patients (Borg, VAS, and mMRC dyspnea scale) before and after therapy using AD, using AD in connection with a belt or a Simeox device and AD in combination with both a belt and Simeox device simultaneously. The best therapeutic effects were generated by the combination of AD with the belt and with the Simeox device. The greatest improvements were observed for FEV1, FVC, PEF, FET, saturation, and patient comfort. In patients <10.5 years of age, the increase in the level of FEV3 and FEV6 was significant in comparison to older patients. Due to their efficacy, therapies connected with AD should be applied not only in hospital departments but also during daily patient care. Given the particular benefits observed in patients <10.5 years of age, it is important to guarantee real accessibility to this form of physiotherapy, especially in this age group.

Exercise versus airway clearance techniques for people with cystic fibrosis.

BACKGROUND: There are many accepted airway clearance techniques (ACTs) for managing the respiratory health of people with cystic fibrosis (CF); none of which demonstrate superiority. Other Cochrane Reviews have reported short-term effects related to mucus transport, but no evidence supporting long-term benefits. Exercise is an alternative ACT thought to produce shearing forces within the lung parenchyma, which enhances mucociliary clearance and the removal of viscous secretions. Recent evidence suggests that some people with CF are using exercise as a substitute for traditional ACTs, yet there is no agreed recommendation for this. Additionally, one of the top 10 research questions identified by people with CF is whether exercise can replace other ACTs. Systematically reviewing the evidence for exercise as a safe and effective ACT will help people with CF decide whether to incorporate this strategy into their treatment plans and potentially reduce their treatment burden. The timing of this review is especially pertinent given the shifting landscape of CF management with the advent of highly-effective small molecule therapies, which are changing the way people with CF are cared for. OBJECTIVES: To compare the effect of exercise to other ACTs for improving respiratory function and other clinical outcomes in people with CF and to assess the potential adverse effects associated with this ACT. SEARCH METHODS: On 28 February 2022, we searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews. We searched online clinical trial registries on 15 February 2022. We emailed authors of studies awaiting classification or potentially eligible abstracts for additional information on 1 February 2021. SELECTION CRITERIA: We selected randomised controlled studies (RCTs) and quasi-RCTs comparing exercise to another ACT in people with CF for at least two treatment sessions. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed risk of bias for the included studies. They assessed the certainty of the evidence using GRADE. Review authors contacted investigators for further relevant information regarding their publications. MAIN RESULTS: We included four RCTs. The 86 participants had a wide range of disease severity (forced expiratory volume in one second (FEV1) ranged from 54% to 95%) and were 7 to 41 years old. Two RCTs were cross-over and two were parallel in design. Participants in one RCT were hospitalised with an acute respiratory exacerbation, whilst the participants in three RCTs were clinically stable. All four RCTs compared exercise either alone or in combination with another ACT, but these were too diverse to allow us to combine results. The certainty of the evidence was very low; we downgraded it due to low participant numbers and high or unclear risks of bias across all domains. Exercise versus active cycle of breathing technique (ACBT) One cross-over trial (18 participants) compared exercise alone to ACBT. There was no change from baseline in our primary outcome FEV1, although it increased in the exercise group before returning to baseline after 30 minutes; we are unsure if exercise affected FEV1 as the evidence is very low-certainty. Similar results were seen for other measures of lung function. No adverse events occurred during the exercise sessions (very low-certainty evidence). We are unsure if ACBT was perceived to be more effective or was the preferred ACT (very low-certainty evidence). 24-hour sputum volume was less in the exercise group than with ACBT (secondary outcome). Exercise capacity, quality of life, adherence, hospitalisations and need for additional antibiotics were not reported. Exercise plus postural drainage and percussion (PD&P) versus PD&P only Two trials (55 participants) compared exercise and PD&P to PD&P alone. At two weeks, one trial narratively reported a greater increase in FEV1 % predicted with PD&P alone. At six months, the other trial reported a greater increase with exercise combined with PD&P, but did not provide data for the PD&P group. We are uncertain whether exercise with PD&P improves FEV1 as the certainty of evidence is very low. Other measures of lung function did not show clear evidence of effect. One trial reported no difference in exercise capacity (maximal work rate) after two weeks. No adverse events were reported (1 trial, 17 participants; very low-certainty evidence). Adherence was high, with all PD&P sessions and 96% of exercise sessions completed (1 trial, 17 participants; very low-certainty evidence). There was no difference between groups in 24-hour sputum volume or in the mean duration of hospitalisation, although the six-month trial reported fewer hospitalisations due to exacerbations in the exercise and PD&P group. Quality of life, ACT preference and need for antibiotics were not reported. Exercise versus underwater positive expiratory pressure (uPEP) One trial (13 participants) compared exercise to uPEP (also known as bubble PEP). No adverse events were recorded in either group (very low-certainty evidence). Trial investigators reported that participants perceived exercise as more fatiguing but also more enjoyable than bubble PEP (very low-certainty evidence). There were no differences found in the total weight of sputum collected during treatment sessions. The trial did not report the primary outcomes (FEV1, quality of life, exercise capacity) or the secondary outcomes (other measures of lung function, adherence, need for antibiotics or hospitalisations). AUTHORS' CONCLUSIONS: As one of the top 10 research questions identified by clinicians and people with CF, it is important to systematically review the literature regarding whether or not exercise is an acceptable and effective ACT, and whether it can replace traditional methods. We identified an insufficient number of trials to conclude whether or not exercise is a suitable alternative ACT, and the diverse design of included trials did not allow for meta-analysis of results. The evidence is very low-certainty, so we are uncertain about the effectiveness of exercise as an ACT. Longer studies examining outcomes that are important to people with CF are required to answer this question.

The effectiveness of the active cycle of breathing technique in patients with chronic respiratory diseases: A systematic review.

BACKGROUND: Active cycle breathing technique (ACBT), which includes cycle of breathing control, thoracic expansion exercises and forced expiratory technique (FET), appears to have beneficial effects in patients with a variety of respiratory diseases. This systematic review provides an update on the new related studies, expanding the evidence base through the last 12 years and specifically evaluating the effectiveness of ACBT on pulmonary function-related outcome variables in patients with chronic respiratory diseases. METHODS: MEDLINE/Pubmed, PEDro, and Cochrane Library for Randomized Controlled Trials were searched between September 2008 and December 2021, in continuance of a previous systematic review, to identify randomized clinical trials and/or crossover studies comparing ACBT to other respiratory treatment techniques in patients with chronic obstructive pulmonary diseases, cystic fibrosis, or bronchiectasis. RESULTS: Eleven studies were included and the quality of most of them was moderate to good. The outcomes most frequently assessed were forced expiratory volume in 1 s (FEV1), sputum wet weight, forced vital capacity (FVC), and peak expiratory flow rate. Secondary outcomes were quality of life and dyspnea. Various comparators were identified and most of them assessed the ACBT as an effective method in comparison with other respiratory treatment modalities. Most studies revealed that ACBT/FET had at least an equally beneficial short-term effect on sputum wet weight, FEV1 and FVC compared to other treatment methods. CONCLUSION: The results of this updating review reinforced the data of a previous systematic review regarding the beneficial impact of ACBT for the short-term improvement in respiratory tract secretions clearance and pulmonary function. ACBT is effective in increasing the expectorated sputum volume, in reducing viscoelasticity of the secretion and in relieving symptoms such as dyspnea.

Fisioterapia com dispositivo individual de pressão expiratória positiva do tipo máscara (PEP)/pressão expiratória nas vias aéreas (EPAP) para o tratamento da Fibrose Cística / Physiotherapy with individual pressure device positive expiratory mask type (PEP)/pressure expiratory airway (EPAP) for the treatment of Cystic Fibrosis

INTRODUÇÃO: A FC é uma doença genética, com incidência nacional de aproximadamente 1:7.576 nascidos vivos. A FC é uma doença complexa e multissistêmica, de característica progressiva e potencialmente letal, que afeta o epitélio do sistema respiratório, gastrointestinal, hepático e geniturinário e que ocorre mais frequentemente em populações descendentes de caucasianos. As manifestações pulmonares da doença são a principal causa de morbimortalidade. A fisioterapia respiratória tem por objetivo preservar a capacidade respiratória e física, e deve ser iniciada logo após o diagnóstico. Existem vários tipos de fisioterapia respiratória, as quais auxiliam no processo de remoção muco. Algumas devem ser realizadas por profissionais treinados, enquanto outras podem ser realizadas pelo próprio paciente após treinamento. A escolha de uma técnica em detrimento da outra leva em conta a idade, o estilo de vida e a preferência do paciente, uma vez que a adesão ao tratamento é responsável pelo sucesso terapêutico. A fisioterapia respiratória deve almejar a independência e autonomia do paciente. TECNOLOGIA: Fisioterapia com dispositivo individual de pressão expiratória positiva do tipo máscara (PEP)/pressão expiratória nas vias aéreas (EPAP) para o tratamento da Fibrose Cística. PERGUNTA: A fisioterapia com equipamento fisioterápico de pressão expiratória positiva de uso individu

Eficacia y seguridad del drenaje pleural con SET de drenaje torácico digital en pacientes adultos con derrame pleural maligno o fístula pulmonar / Efficacy and safety of pleural drainage with digital chest drainage SET in adult patients with malignant pleural effusion or pulmonary fistula

INTRODUCCIÓN: El presente documento de evaluación de tecnología sanitaria (ETS) expone la evaluación de la eficacia y seguridad del drenaje pleural con set de drenaje torácico digital (SDTD) en pacientes adultos con derrame pleural maligno (DPM) o fístula pulmonar en comparación con el set de drenaje torácico convencional (SDTC). El derrame pleural maligno (DPM) y las fistulas broncopleurales (FBP) son condiciones amenazantes para la vida del paciente. El DPM es una condición que ocurre en su mayoría en pacientes en etapas avanzadas de cáncer y cuya expectativa de vida es muy baja. Por otro lado, las FBP son comunicaciones patológicas entre el árbol bronquial y espacio pulmonar, que aparecen como consecuencia de una cirugía de reseccion pulmonar, por lo general por causas oncológicas, y con menor frecuencia debido a quimioterapias y radioterapias. El DPM y las FBP pueden producir la invasión de colecciones líquidas y aire en el espacio pleural; causando desestabilización de su presión negativa1 y consecuentemente colapso pulmonar y disnea respiratoria. Ambas condiciones deben ser tratadas a tiempo para favorecer el restablecimiento del espacio pleural y reexpansión pulmonar. Uno de los tratamientos del DPM o las FBP es el drenaje pleural, que permite descomprimir el espacio pleural del exceso de líquido o aire, permitiendo una mejor respiración, así como menor compromiso de otros órganos vitales. En el contexto de EsSalud, los pacientes con diagnóstico de DPM o FBP son tratados con la tecnología set de drenaje torácico convencional (SDTC); sin embargo, los médicos especialistas del Hospital Nacional Edgardo Rebagliati Martins (HNERM) han solicitado la incorporación al Petitorio de EsSalud de la tecnología sanitaria set de drenaje torácico digital (SDTD). La justificación de la inclusión de esta tecnología según los especialistas es que el SDTC requiere de un sistema de succión de pared, que limitaría la movilidad del paciente. Además, la lectura de los indicadores de drenaje y fuga aérea con esta tecnología debe ser realizada cualitativamente por un profesional, pudiendo existir subjetividad de la evaluación, así como variabilidad interobservador. Por el contrario, señalan que el SDTD cuenta con un sistema de succión portátil, y además, permite un registro digital evolutivo de los indicadores de ausencia de drenaje y fuga aérea en estos pacientes, lo que podría traducirse en un mayor beneficio clínico para ellos, en términos de recuperación y tiempo de estancia hospitalaria. METODOLOGÍA: Se realizó una búsqueda sistemática de información con el objetivo de identificar la mejor evidencia disponible a la fecha (02 de marzo de 2020) sobre la eficacia y seguridad del drenaje pleural con SDTD, comparado con SDTC, en pacientes adultos con DPM o FBP. Se realizó una búsqueda bibliográfica avanzada en las bases de datos de PubMed, Cochrane Database of Systematic Reviews y Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS). La búsqueda sistemática fue suplementada con una búsqueda manual en la lista de referencias bibliográficas de la evidencia incluida en el presente dictamen. Además, se realizó una búsqueda de literatura gris en el motor de búsqueda Google, a fin de poder identificar GPC y ETS de relevancia que pudiesen haber sido omitidas por la estrategia de búsqueda o que no hayan sido publicadas en las bases de datos consideradas. Asimismo, se realizó una búsqueda dentro de bases de datos pertenecientes a grupos que realizan ETS y GPC, incluyendo, el National Institute for Health and Care Excellence (NICE), la Canadian Agency for Drugs and Technologies in Health (CADTH), la Haute Autorité de Santé (HAS), el Institut für Qualitát und Wirtschaftlichkeit im Gesundheitswesen (IQWiG), además de la Base Regional de Informes de Evaluación de Tecnologías en Salud de las Américas (BRISA) y páginas web de sociedades especializadas en el manejo del DPM y las FBP. Por último, se realizó una búsqueda de estudios clínicos en ejecución o aún no publicados en las páginas web de ClinicalTrials.gov y del International Clinical Trial Registry Platform (ICTRP). RESULTADOS: A través de la búsqueda bibliográfica en las bases de datos, se identificaron 420 documentos. Luego de eliminar los documentos duplicados, 401 fueron elegibles para tamizaje por título y resumen. De ellos, 20 documentos fueron elegibles para evaluación a texto completo. Finalmente, dos documentos fueron elegidos para incluirse en el presente dictamen. Como producto de la búsqueda bibliográfica y selección sistemática de la evidencia, se han incluido dos GPC que emiten recomendaciones para el tratamiento de pacientes con DPM (Tabla 1). No se encontraron RS con o sin MA, ECA o estudios observacionales elegibles para evaluación. A continuación se reporta brevemente el cuerpo de evidencia de acuerdo con la pirámide de jerarquía de Haynes, siguiendo lo indicado en los criterios de elegibilidad. CONCLUSIONES: El presente dictamen preliminar tuvo por objetivo realizar una síntesis de la mejor evidencia disponible a la fecha (02 de marzo del 2021) sobre la eficacia y seguridad del drenaje pleural empleando SDTD en comparación con SDTC en pacientes con DPM o FBP con indicación de drenaje pleural. En el contexto de EsSalud, los pacientes con DPM o FBP son tratados con drenaje pleural empleando SDTC; sin embargo, los especialistas de la entidad han propuesto la incorporación de SDTD debido a que este superaría algunos potenciales inconvenientes de la tecnología de uso actual en EsSalud, como el riesgo de evaluación subjetiva de ausencia de drenaje y fuga aérea, y la necesidad de estar conectada a un sistema de succión de pared. Por ello, se realizó una evaluación de la eficacia y seguridad de SDTD, en comparación con SDTC, para el manejo de estos pacientes. Luego de la búsqueda sistemática de información (02 de marzo del 2021) se incluyeron dos GPC sobre el manejo de pacientes con DPM para su evaluación (National Institute for Health and Care Excellence 2019, Feller-Kopman et al. 2018). No se encontraron GPC sobre el manejo de pacientes con FBP. Tampoco se encontraron ECA, RS con o sin MA, o estudios obseservacionales que comparen a las tecnologías SDTD y SDTC en procedimientos de drenaje pleural en pacientes con DPM o FBP. Ninguna de las GPC evaluadas mencionó al SDTD o SDTC entre sus recomendaciones de drenaje pleural para el manejo paliativo de pacientes con DPM. Aunque una de las GPC recomienda la colocación de catéter permanente (tecnología que puede ser conectada a SDTD o SDTC) para realizar el drenaje pleural, no se mencionó a qué sistema de drenaje se debe conectarse el dispositivo para realizar el procedimiento (Feller-Kopman et al. 2018). Asimismo, ninguno de los estudios empleados como sustento para estas recomendaciones menciona que sistema de drenaje se utilizó para llevar a cabo el drenaje pleural. En consecuencia, existe incertidumbre sobre cuál es el sistema de drenaje de elección (SDTD o SDTC) para llevar a cabo estos procedimientos. Durante la búsqueda de la literatura se observaron estudios de bajo nivel metodológico (reportes de casos y resúmenes de congreso) que evaluaron el uso de la tecnología SDTD en pacientes con DPM o FBP. Esto se condice con lo mencionado por la literatura acerca de la escasa evidencia de alto nivel metodológico para el cuidado paliativo de pacientes, como es el caso de pacientes con DPM. En ese sentido, para realizar una evaluación objetiva de la eficacia y seguridad de la tecnología SDTD es necesario contar con ECA bien diseñados. Por otro lado, aunque existen estudios de alto nivel metodológico (i.e. ECA) que comparan a las tecnologías SDTD y SDTC, estos fueron realizados en pacientes con marcadas diferencias en la fisiopatología, pronóstico, necesidad de tratamiento y objetivo del drenaje pleural, en comparación con la población de pacientes con DPM o FBP. Por lo tanto, los resultados de estos estudios no pueden extrapolarse a los pacientes con DPM o FBP. De igual manera, es preciso señalar que, según el fabricante de la tecnología SDTD solicitada, la indicación de uso de la misma es para drenaje torácico y pleural de pacientes sometidos a cirugía torácica o cardiaca, la cual difiere de la población de interés para la PICO, y explicaría la ausencia de estudios de alto nivel metodológico en esta población. Por todo lo expuesto, debido a que a la fecha no existen argumentos técnicos que apoyen el uso de la tecnología SDTD en pacientes con DPM o FBP, y que además, la indicación de uso de la tecnología no incluye a esta población, sino a pacientes sometidos a cirugía torácica y cardiaca, el IETSI no aprueba el uso de SDTD en pacientes adultos con derrame pleural maligno o fístula pulmonar.

The effects of the addition of a new airway clearance device to chest physiotherapy in children with cystic fibrosis pulmonary exacerbations.

BACKGROUND: Chest physiotherapy plays a crucial role in managing cystic fibrosis, especially during pulmonary exacerbations. This study evaluated the effects of adding a new airway clearance device to chest physiotherapy in subjects with cystic fibrosis hospitalised due to pulmonary exacerbations. METHODS: This prospective open-label study was carried out at the Pediatric Cystic Fibrosis Centre in Poland between October 2017 and August 2018. Cystic fibrosis patients aged 10 to 18 years who were admitted to the hospital and required intravenous antibiotic therapy due to pulmonary exacerbations were consecutively allocated (1:1) to either chest physiotherapy alone or chest physiotherapy with a new airway clearance device (Simeox; PhysioAssist). Patients performed spirometry and multiple-breath nitrogen washout for lung clearance index assessment upon admission and prior to discharge. RESULTS: Forty-eight cystic fibrosis patients were included (24 in each group). Spirometry parameters in both groups improved significantly after intravenous antibiotic therapy. A significant improvement in the maximum expiratory flow at 25% of forced vital capacity was observed only in the group with a new airway clearance device (p < 0.01 vs. baseline). Trends towards a lower lung clearance index ratio were similar in both groups. No adverse events were observed in either group. CONCLUSIONS: Spirometry parameters increased significantly in cystic fibrosis patients treated for pulmonary exacerbations with intravenous antibiotic therapy and intensive chest physiotherapy. The new airway clearance device was safe and well tolerated when added to chest physiotherapy and may be another option for the treatment of pulmonary exacerbation in cystic fibrosis.

Rehabilitation Therapy for a COVID-19 Patient Who Received Mechanical Ventilation in Japan.

A 65-yr-old man visited a primary care hospital with a continued fever of 38°C for 3 days. As his fever did not improve until 8 days after, he was admitted into another acute care hospital, where his respiratory condition rapidly worsened. Therefore, the patient was transferred to our hospital. On the day of transfer (day 1), he was started on mechanical ventilation. COVID-19 was diagnosed using a polymerase chain reaction assay 6 days after admission (day 6). The rehabilitation therapy was begun on day 6. The initial rehabilitation programs focused on positioning and postural drainage. The patient was extubated on day 19, and he began standing and stepping on the same day. Gait exercises began on day 22, and endurance training was initiated on day 28. The patient was discharged from our hospital on day 34 as he met the physical function milestones. One month after discharge, the Medical Research Council sum score and Barthel Index had each improved; therefore, muscle strength and daily activities had returned to normal. It was assumed that mobilization should be performed as soon as possible after the end of sedation during the acute phase of severe COVID-19 infection in patients receiving mechanical ventilation.

Effectiveness Active Cycle of Breathing Technique (ACBT) with Pursed Lips Breathing Technique (PLBT) to tripod position in increase oxygen saturation in patients with COPD, West Sumatera

Chronic Obstructive Pulmonary Disease (COPD) is a chronic lung disease characterized by obstruction or obstruction of airflow in a reversible or partial nonreversible airway. Dyspnea is a common symptom in COPD sufferers; this can cause problems with oxygen saturation, or the oxygen saturation value is below normal. Non-pharmacological actions given in the form of breathing exercises can be done by a nurse to help reduce shortness of breath in COPD patients. The exercise is given by adjusting the resting position that is comfortable and comfortable so that the extra breath muscles can work well. The position that can do the position of the tripod with Active Cycle of Breathing and Pursed lips are breathing so that shortness of breath is reduced and SaO2 can have increased so that more oxygen has obtained in Lung Hospital, West Sumatra. This research is quantitative research, with quasi-experimental research methods. They used two pre-test-posttest design groups. The sample in this study amounted to 30 people with quota sampling technique. In this study showed that there was a difference in the increase in oxygen saturation of COPD patients which was effective in the tripod position group with Active Cycle Breathing Technique (ACBT) with a p-value of 0.00 while in the tripod position group with the Active Respiratory and Lip Cycle there was a difference of p-value 0.023. It has concluded that the tripod position with ACT and PBLT could increase oxygen saturation and nasal breathlessness reduced, but the tripod position with ACT is more effective in COP patients because with chronic respiratory patients who are short of breath due to sputum buildup, then with ACT will clean the airway and the flow of the road effective breathing so that shortness of breath have reduced and oxygen saturation increases. Furthermore, it has recommended that in hospitals, especially nurses, in dealing with COPD patients in addition to the correct position of breathing exercises with ACT to help patients

Bubble-positive expiratory pressure device and sputum clearance in bronchiectasis: A randomised cross-over study.

OBJECTIVES: The bubble-positive expiratory pressure (PEP) device may be used for sputum clearance in people with daily sputum production. However, this device has never been studied in people with bronchiectasis. Hence, the objective of this study was to compare the effect of bubble-PEP device, the active cycle of breathing technique (ACBT) and no intervention (control) on sputum clearance in people with bronchiectasis. METHODS: This was a prospective, randomised cross-over trial with concealed allocation, assessor blinding and intention-to-treat analysis. Adult participants with stable bronchiectasis and productive of sputum daily were recruited. Participants performed 30-min of bubble-PEP, ACBT or control in random order whilst sitting, followed by 60-min of quiet sitting, on three separate days at the same time within a 10-day period. Primary outcome measure was wet weight of expectorated sputum during 30-min intervention, 60-min post intervention and total wet weight (30 min plus 60 min). RESULTS: Thirty-five-participants (11 males, mean [standard deviation] age 75 [8] years, forced expiratory volume in 1 s 72 [20] % predicted) were recruited and 34 completed the study. There was no significant difference in sputum wet weight between bubble-PEP and ACBT during 30-min intervention (mean difference [95% confidence interval]) -0.59 g [-1.37, 0.19] and total wet weight (0.74 g [-0.54, 2.02]). Sputum wet weight was significantly greater in bubble-PEP than ACBT at 60-min post intervention (1.33 g [0.19, 2.47]). CONCLUSION: Sputum wet weight was significantly greater with bubble-PEP than control at all time periods, and greater than ACBT at 60-min-post. Bubble-PEP could be considered an alternative sputum clearance technique to ACBT.

Positive expiratory pressure physiotherapy for airway clearance in people with cystic fibrosis.

BACKGROUND: Chest physiotherapy is widely prescribed to assist the clearance of airway secretions in people with cystic fibrosis (CF). Positive expiratory pressure (PEP) devices provide back pressure to the airways during expiration. This may improve clearance by building up gas behind mucus via collateral ventilation and by temporarily increasing functional residual capacity. The developers of the PEP technique recommend using PEP with a mask in order to avoid air leaks via the upper airways and mouth. In addition, increasing forced residual capacity (FRC) has not been demonstrated using mouthpiece PEP. Given the widespread use of PEP devices, there is a need to determine the evidence for their effect. This is an update of a previously published review. OBJECTIVES: To determine the effectiveness and acceptability of PEP devices compared to other forms of physiotherapy as a means of improving mucus clearance and other outcomes in people with CF. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. The electronic database CINAHL was also searched from 1982 to 2017. Most recent search of the Group's CF Trials Register: 20 February 2019. SELECTION CRITERIA: Randomised controlled studies in which PEP was compared with any other form of physiotherapy in people with CF. This included, postural drainage and percussion (PDPV), active cycle of breathing techniques (ACBT), oscillating PEP devices, thoracic oscillating devices, bilevel positive airway pressure (BiPaP) and exercise. DATA COLLECTION AND ANALYSIS: Three authors independently applied the inclusion and exclusion criteria to publications, assessed the risk of bias of the included studies and assessed the quality of the evidence using the GRADE recommendations. MAIN RESULTS: A total of 28 studies (involving 788 children and adults) were included in the review; 18 studies involving 296 participants were cross-over in design. Data were not published in sufficient detail in most of these studies to perform any meta-analysis. In 22 of the 28 studies the PEP technique was performed using a mask, in three of the studies a mouthpiece was used with nose clips and in three studies it was unclear whether a mask or mouthpiece was used. These studies compared PEP to ACBT, autogenic drainage (AD), oral oscillating PEP devices, high-frequency chest wall oscillation (HFCWO) and BiPaP and exercise. Forced expiratory volume in one second was the review's primary outcome and the most frequently reported outcome in the studies (24 studies, 716 participants). Single interventions or series of treatments that continued for up to three months demonstrated little or no difference in effect between PEP and other methods of airway clearance on this outcome (low- to moderate-quality evidence). However, long-term studies had equivocal or conflicting results regarding the effect on this outcome (low- to moderate-quality evidence). A second primary outcome was the number of respiratory exacerbations. There was a lower exacerbation rate in participants using PEP compared to other techniques when used with a mask for at least one year (five studies, 232 participants; moderate- to high-quality evidence). In one of the included studies which used PEP with a mouthpiece, it was reported (personal communication) that there was no difference in the number of respiratory exacerbations (66 participants, low-quality evidence). Participant preference was reported in 10 studies; and in all studies with an intervention period of at least one month, this was in favour of PEP. The results for the remaining outcome measures (including our third primary outcome of mucus clearance) were not examined or reported in sufficient detail to provide any high-quality evidence; only very low- to moderate-quality evidence was available for other outcomes. There was limited evidence reported on adverse events; these were measured in five studies, two of which found no events. In a study where infants performing either PEP or PDPV experienced some gastro-oesophageal reflux , this was more severe in the PDPV group (26 infants, low-quality evidence). In PEP versus oscillating PEP, adverse events were only reported in the flutter group (five participants complained of dizziness, which improved after further instructions on device use was provided) (22 participants, low-quality evidence). In PEP versus HFCWO, from one long-term high-quality study (107 participants) there was little or no difference in terms of number of adverse events; however, those in the PEP group had fewer adverse events related to the lower airways when compared to HFCWO (high-certainty evidence). Many studies had a risk of bias as they did not report how the randomisation sequence was either generated or concealed. Most studies reported the number of dropouts and also reported on all planned outcome measures. AUTHORS' CONCLUSIONS: The evidence provided by this review is of variable quality, but suggests that all techniques and devices described may have a place in the clinical treatment of people with CF. Following meta-analyses of the effects of PEP versus other airway clearance techniques on lung function and patient preference, this Cochrane Review demonstrated that there was high-quality evidence that showed a significant reduction in pulmonary exacerbations when PEP using a mask was compared with HFCWO. It is important to note that airway clearance techniques should be individualised throughout life according to developmental stages, patient preferences, pulmonary symptoms and lung function. This also applies as conditions vary between baseline function and pulmonary exacerbations.

Acute Effects of Oscillatory PEP and Thoracic Compression on Secretion Removal and Impedance of the Respiratory System in Non-Cystic Fibrosis Bronchiectasis.

BACKGROUND: Bronchiectasis is characterized by abnormal and permanent dilatation of the bronchi, caused mainly by the progression of inflammatory processes and loss of the ability to remove mucus. Techniques to clear the airways are essential for the treatment of these patients. In this study, we aimed to evaluate the acute effects of oscillatory PEP and thoracic compression on both the clearance of secretions and impedance of airways in subjects with bronchiectasis. METHODS: This was a randomized crossover single-blinded study that involved both subjects with bronchiectasis and healthy subjects evaluated by using an impulse oscillometry system, which assessed resistance at 5 Hz and resistance 20 Hz, reactance at 5 Hz, reactance area, and resonant frequency, before, after, and 30 min after oscillatory PEP, chest compression, or control sessions. Dry and total weights, adhesiveness, purulence of the expectorated secretions, the dyspnea scale score, the acceptability and tolerance scale score, pulse oximetry, and difficulty in expectoration were also assessed. RESULTS: The dry and total weights of secretions were higher after the use of the oscillatory PEP technique than those in a control session (P = .005 and P = .039, respectively). In the bronchiectasis group, there was a decrease after oscillatory PEP in total airway resistance (P = .04), peripheral resistance (P = .005), and reactance area (P = .001). After compression, there was a decrease in peripheral resistance Hz (P = .001) and reactance area (P = .001). In the healthy group, there was an increase in resistance at 5 Hz (P = .02) after oscillatory PEP. There were no differences in acceptability and tolerance, dyspnea, and oxygen saturation. CONCLUSIONS: The oscillatory PEP technique was effective for the removal of secretions and in decreasing total and peripheral respiratory system resistance; thoracic compression had comparable positive effects on the peripheral resistance. Both techniques were safe and well tolerated by the subjects with bronchiectasis. ClinicalTrials.gov registration NCT02509637.).

Bilateral costotransverse and local continuous chemotherapy approach for debridement, fixation, and fusion of contiguous multisegmental thoracic spinal tuberculosis: A retrospective study.

The study aims to evaluate the clinical efficacy of bilateral costotransverse debridement, transpedicular fixation, fusion, and local continuous chemotherapy in 20 patients of contiguous multisegmental thoracic spinal tuberculosis (CMTSTB). We analyzed 20 patients with contiguous thoracic spinal tuberculosis (TB) who underwent surgery via bilateral costotransverse debridement, fusion, posterior instrumentation, and postural drainage with local continuous chemotherapy. The clinical outcomes were evaluated in terms of kyphotic angle, bone fusion, neurologic status, erythrocyte sedimentation rate (ESR), and intraoperative and postoperative complications. All of the patients (8M/12F), averaged 45.8 ±â€Š15.6 years old. The mean duration of postoperative follow-up was 30.7 ±â€Š4.0 months. There was no recurrent TB infection. The values of ESR returned to normal levels at final follow-up. All patients got bony fusion within 8.1 ±â€Š2.3 months after surgery. The average preoperative Cobb angle was 39.9°â€Š±â€Š8.6°, correcting to 9.8°â€Š±â€Š2.3° postoperatively and 10.8°â€Š±â€Š2.3° at the last follow-up. All patients with neurological deficit had dramatic improvement at the final follow-up. Our results showed that bilateral costotransverse surgery and local continuous chemotherapy are feasible and effective procedures in the treatment of CMTSTB. The approach can provide radical debridement, rebuild spinal stability, and cure TB.

The benefit of daily sputum suction via bronchoscopy in patients of chronic obstructive pulmonary disease with ventilators: A randomized controlled trial.

BACKGROUND: To compare the clinical values of bronchoscopic sputum suction and general sputum suction in respiratory failure patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) combined with sequential invasive-noninvasive mechanical ventilation at the pulmonary infection control (PIC) window (period of lower sputum production, with thinner viscosity and lighter color, and alleviated clinical signs of infection). METHODS: Patients with AECOPD-induced respiratory failure received orotracheal intubation mechanical ventilation and were randomly divided into bronchoscopic sputum suction group or general sputum suction group, and who were then treated with sequential invasive-noninvasive mechanical ventilation at PIC window (both groups). Baseline data, postoperative blood gas conditions, and postoperative clinical parameters of the patients such as appearance of PIC window, time of invasive ventilation, total time of ventilation, hospital stay, weaning success rate, reintubation rate, ventilator-associated pneumonia (VAP) incidence, and fatality rate were measured to compare the effect of 2 different ways of sputum suction. RESULTS: There was no significant difference in baseline characteristics, postoperative blood gas conditions, between 2 groups (all P > .05). Nevertheless, the bronchoscopic sputum suction group showed earlier appearance of PIC window, shorter time of invasive ventilation, total time of ventilation and hospital stay, lower reintubation rate, VAP incidence and fatality rate, and higher weaning success rate than the general sputum suction group (all P < .05). CONCLUSION: Bronchoscopic sputum suction combined with sequential invasive-noninvasive mechanical ventilation at PIC window showed clinical effects in treating respiratory failure patients with AECOPD.

Secretion clearance strategies in Australian and New Zealand Intensive Care Units.

INTRODUCTION/AIMS: To describe the processes of care for secretion clearance in adult, intubated and mechanically ventilated patients in Australian and New Zealand Intensive Care Units (ICUs). METHODS/RESULTS: A prospective, cross-sectional study was conducted through the Australian and New Zealand Intensive Care Society Clinical Trials Group (ANZICS CTG) Point Prevalence Program. Forty-seven ICUs collected data from 230 patients intubated and ventilated on the study day. Secretion clearance techniques beyond standard suctioning were used in 84/230 (37%) of patients during the study period. Chest wall vibration 34/84 (40%), manual lung hyperinflation 24/84 (29%), chest wall percussion 20/84 (24%), postural drainage/patient positioning 17/84 (20%) and other techniques including mobilisation 15/84 (18%), were the most common secretion clearance techniques employed. On average (SD), patients received airway suctioning 8.8 (5.0) times during the 24-h study period. Mucus plugging events were infrequent (2.7%). The additional secretion clearance techniques were provided by physiotherapy staff in 24/47 (51%) ICUs and by both nursing and physiotherapy staff in the remaining 23/47 (49%) ICUs. CONCLUSION: One-third of intubated and ventilated patients received additional secretion clearance techniques. Mucus plugging events were infrequent with these additional secretion clearance approaches. Prospective studies must examine additional secretion clearance practices, prevalence of mucus plugging episodes and impact on patient outcomes.

[Manual airway clearance techniques in adults and adolescents: What level of evidence?] / Techniques manuelles de drainage bronchique des adultes et adolescents : quel niveau de preuve ?

BACKGROUND: The aim of this systematic literature review was to grade the levels of evidence of the most widely used manual airway clearance techniques. METHODS: A literature search was conducted over the period 1995-2014 from the Medline, PEDro, ScienceDirect, Cochrane Library, REEDOC and kinedoc databases, with the following keywords: "postural drainage", "manual vibrations", "manual chest percussion", "directed cough", "increased expiratory flow", "ELTGOL", "autogenic drainage" and "active cycle of breathing technique". RESULTS: Two-hundred and fifty-six articles were identified. After removing duplicates and reading the titles and abstracts, 63 articles were selected, including 9 systematic reviews. This work highlights the lack of useful scientific data and the difficulty of determining levels of evidence for manual airway clearance techniques. Techniques were assessed principally with patients with sputum production (cystic fibrosis, DDB, COPD, etc.). It also shows the limited pertinence of outcome measures to quantify congestion and hence the efficacy of airway clearance techniques. CONCLUSION: The 1994 consensus conference summary table classifying airway clearance techniques according to physical mechanism provides an interesting tool for assessment, grouping together techniques having identical mechanisms of action. From the findings of the present systematic review, it appears that only ELTGOL, autogenic drainage and ACBT present levels of evidence "B". All other techniques have lower levels of evidence. LEVEL OF EVIDENCE: II.

Analysis of specialized nursing on respiratory functions in thoracotomy patients.

To analyze the nursing effect on the respiratory function of thoracotomy patients, sixty thoracotomy hospitalized patients were studied. The subjects were divided into a normal group (A) and an observation group (B). The patients in group A received routine nursing only, while those in group B received chest physiotherapy as well as routine nursing. Afterwards, the respiratory function indicators of the two groups were compared and a data analysis was performed. The results showed that the partial pressure of oxygen (PO2) value of the patients in group B was greater than that of the patients in group A while the partial pressure of carbon dioxide (PCO2) value in group B was smaller than that in group A, and there was a significant difference between the two groups (p less than 0.05). The vital capacity under normal circumstances and forced breathing of group B were greater than that of group A and the difference was statistically significant (p less than 0.05). The incidence of complications (atelectasis, respiratory infections, pleural effusion) was statistically significant between the two groups (p less than 0.05). The degree of autonomic respiratory dysfunction in group B was lower than that in group A, and there was a significant difference (p less than 0.05), suggesting that the respiratory function in patients receiving chest physiotherapy improved significantly.

Autogenic drainage for airway clearance in cystic fibrosis.

BACKGROUND: Autogenic drainage is an airway clearance technique that was developed by Jean Chevaillier in 1967. The technique is characterised by breathing control using expiratory airflow to mobilise secretions from smaller to larger airways. Secretions are cleared independently by adjusting the depth and speed of respiration in a sequence of controlled breathing techniques during exhalation. The technique requires training, concentration and effort from the individual. It is important to systematically review the evidence demonstrating that autogenic drainage is an effective intervention for people with cystic fibrosis. OBJECTIVES: To compare the clinical effectiveness of autogenic drainage in people with cystic fibrosis with other physiotherapy airway clearance techniques. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews, as well as two trials registers (31 August 2017).Dtae of most recent search of the Cochrane Cystic Fibrosis Trials Register: 25 September 2017. SELECTION CRITERIA: We identified randomised and quasi-randomised controlled studies comparing autogenic drainage to another airway clearance technique or no therapy in people with cystic fibrosis for at least two treatment sessions. DATA COLLECTION AND ANALYSIS: Data extraction and assessments of risk of bias were independently performed by two authors. The authors assessed the quality of the evidence using the GRADE system. The authors contacted two investigators for further information pertinent to their published studies. MAIN RESULTS: Searches retrieved 35 references to 21 individual studies, of which seven (n = 208) were eligible for inclusion. One study was of parallel design with the remaining six being cross-over in design; participant numbers ranged from 17 to 75. The total study duration varied between four days and two years. The age of participants ranged between seven and 63 years with a wide range of disease severity reported. Six studies enrolled participants who were clinically stable, whilst participants in one study had been hospitalised with an infective exacerbation. All studies compared autogenic drainage to one (or more) other recognised airway clearance technique. Exercise is commonly used as an alternative therapy by people with cystic fibrosis; however, there were no studies identified comparing exercise with autogenic drainage.The quality of the evidence was generally low or very low. The main reasons for downgrading the level of evidence were the frequent use of a cross-over design, outcome reporting bias and the inability to blind participants.The review's primary outcome, forced expiratory volume in one second, was the most common outcome measured and was reported by all seven studies; only three studies reported on quality of life (also a primary outcome of the review). One study reported on adverse events and described a decrease in oxygen saturation levels whilst performing active cycle of breathing techniques, but not with autogenic drainage. Six of the seven included studies measured forced vital capacity and three of the studies used mid peak expiratory flow (per cent predicted) as an outcome. Six studies reported sputum weight. Less commonly used outcomes included oxygen saturation levels, personal preference, hospital admissions or intravenous antibiotics. There were no statistically significant differences found between any of the techniques used with respect to the outcomes measured except when autogenic drainage was described as being the preferred technique of the participants in one study over postural drainage and percussion. AUTHORS' CONCLUSIONS: Autogenic drainage is a challenging technique that requires commitment from the individual. As such, this intervention merits systematic review to ensure its effectiveness for people with cystic fibrosis. From the studies assessed, autogenic drainage was not found to be superior to any other form of airway clearance technique. Larger studies are required to better evaluate autogenic drainage in comparison to other airway clearance techniques in view of the relatively small number of participants in this review and the complex study designs. The studies recruited a range of participants and were not powered to assess non-inferiority. The varied length and design of the studies made the analysis of pooled data challenging.
