ABSTRACT
Background: The use of instruments in clinical practice with measurement properties tested is highly recommended, in order to provide adequate assessment and measurement of outcomes. Objective: To calculate the minimum clinically important difference (MCID) and responsiveness of the Perme Intensive Care Unit Mobility Score (Perme Score). Methods: This retrospective, multicentric study investigated the clinimetric properties of MCID, estimated by constructing the Receiver Operating Characteristic (ROC). Maximizing sensitivity and specificity by Youden's, the ROC curve calibration was performed by the Hosmer and Lemeshow goodness-of-fit test. Additionally, we established the responsiveness, floor and ceiling effects, internal consistency, and predictive validity of the Perme Score. Results: A total of 1.200 adult patients records from four mixed general intensive care units (ICUs) were included. To analyze which difference clinically reflects a relevant evolution we calculated the area under the curve (AUC) of 0.96 (95% CI: 0.95-0.98), and the optimal cut-off value of 7.0 points was established. No substantial floor (8.8%) or ceiling effects (4.9%) were observed at ICU discharge. However, a moderate floor effect was observed at ICU admission (19.3%), in contrast to a very low incidence of ceiling effect (0.6%). The Perme Score at ICU admission was associated with hospital mortality, OR 0.86 (95% CI: 0.82-0.91), and the predictive validity for ICU stay presented a mean ratio of 0.97 (95% CI: 0.96-0.98). Conclusion: Our findings support the establishment of the minimum clinically important difference and responsiveness of the Perme Score as a measure of mobility status in the ICU.
Antecedentes: Se recomienda encarecidamente el uso de instrumentos en la práctica clínica con propiedades de medición probadas, con el fin de proporcionar una evaluación y medición adecuada de los resultados. Objetivo: Calcular la diferencia mínima clínicamente importante (MCID) y la capacidad de respuesta de la puntuación de movilidad de la unidad de cuidados intensivos de Perme (Perme Score). Métodos: Este estudio multicéntrico retrospectivo investigó las propiedades clinimétricas de MCID, estimadas mediante la construcción de la característica operativa del receptor (ROC). Maximizando la sensibilidad y especificidad mediante la prueba de Youden, la calibración de la curva ROC se realizó mediante la prueba de bondad de ajuste de Hosmer y Lemeshow. Además, establecimos la capacidad de respuesta, los efectos suelo y techo, la consistencia interna y la validez predictiva del Perme Score. Resultados: Se incluyeron un total de 1,200 registros de pacientes adultos de cuatro unidades de cuidados intensivos (UCI) generales mixtas. Para analizar qué diferencia refleja clínicamente una evolución relevante calculamos el área bajo la curva (AUC) de 0.96 (95% CI: 0.95-0.98); y se estableció el valor de corte óptimo de 7.0 puntos. No se observaron efectos suelo (8.8%) o techo (4.9%) sustanciales al alta de la UCI. Sin embargo, se observó un efecto suelo moderado al ingreso en la UCI (19.3%), en contraste con una incidencia muy baja del efecto techo (0.6%). El Perme Score al ingreso en UCI se asoció con la mortalidad hospitalaria, OR 0.86 (95% CI: 0.82-0.91), y la validez predictiva de estancia en UCI presentó una relación media de 0.97 (95% CI: 0.96-0.98). Conclusiones: Nuestros hallazgos respaldan el establecimiento de la diferencia mínima clínicamente importante y la capacidad de respuesta de el Perme Score como medida del estado de movilidad en la UCI.
ABSTRACT
Abstract Objective: To evaluate and compare peripheral, pelvic floor, respiratory muscle strength, and functionality in the immediate puerperium of normal delivery and cesarean section. Methods: This is a cross-sectional study that verified respiratory, pelvic floor, peripheral, and functional muscle strength through manovacuometry, pelvic floor functional assessment (PFF), dynamometry, and the Time Up and Go (TUG) test, respectively. The groups were divided according to the type of delivery, into a cesarean section group and a normal parturition group. Results: The sample was composed of 72 postpartum puerperae, 36 of normal parturition, and 36 of cesarean section, evaluated before hospital discharge, mean age ranged from 25.56 ± 6.28 and 28.57 ± 6.47 years in puerperae of normal parturition and cesarean section respectively. Cesarean showed higher pelvic floor strength (PFF) compared to normal parturition (p < 0.002), but puerperae from normal delivery showed better functionality (p < 0.001). As for peripheral muscle strength and respiratory muscle strength, there was no significance when comparing the types of parturirion. Conclusion: There is a reduction in pelvic muscle strength in puerperae of normal delivery and a decrease in functionality in puerperae of cesarean section.
Resumo Objetivo: Avaliar e comparar o pavimento pélvico periférico, a força muscular respiratória e a funcionalidade no puerpério imediato do parto normal e da cesariana. Métodos: Este é um estudo transversal que verificou a força muscular respiratória, pavimento pélvico, periférico e funcional através da manovacuometria, avaliação funcional do pavimento pélvico (PFF), dinamometria, e o teste Time Up e Go (TUG), respectivamente. Os grupos foram divididos de acordo com o tipo de parto, num grupo de cesariana e num grupo de parto normal. Resultados: A amostra foi composta por 72 puérperas pós-parto, 36 de parto normal e 36 de cesariana, avaliados antes da alta hospitalar, a idade média variou entre 25,56 ± 6,28 e 28,57 ± 6,47 anos em puérperas de parto normal e cesariana, respectivamente. A cesariana mostrou maior resistência do pavimento pélvico (TFP) em comparação com o parto normal (p < 0,002), mas as puérperas de parto normal mostraram melhor funcionalidade (p < 0,001). Quanto à força muscular periférica e à força muscular respiratória, não houve significado ao comparar os tipos de parto. Conclusão: Há uma redução da força muscular pélvica em puérperas de parto normal e uma diminuição da funcionalidade em puérperas de cesarianas.

Background and Objectives: Perform the bag squeezing and PEEP-ZEEP techniques associated with manual chest compression in mechanically ventilated cardiac patients in order to observe their effectiveness in the removal of pulmonary secretions and safety from a hemodynamic and ventilatory point of view. Methods: This is a randomized crossover clinical trial developed in a hospital in southern Brazil. We included hemodynamically stable male and female patients aged over 18 years who used invasive mechanical ventilation for at least 48 h. The control group was established for the bag-squeezing technique and the intervention group for the PEEP-ZEEP maneuver, both associated with manual chest compression. Tracheal aspiration was performed 2 h before in order to match the groups in relation to the volume of secretion, and also immediately at the end of the techniques in order to measure the amount of secretion collected. Results: The sample had 36 individuals with a mean age of 70.3 years, 21% of the patients were male, and the majority (10.4%) were hospitalized for ischemic heart disease. DBP (p = 0.024), MAP (p = 0.004) and RR (p = 0.041) showed a significant difference in the post-moment in both groups. There was a significant difference in the reduction of peak pressure values (p = 0.011), in the moment after performing the techniques, and also in the Cdyn (p = 0.004) in the control group versus moment. Conclusions: Both maneuvers are safe in terms of hemodynamics and ventilatory mechanics, in addition to being capable of favoring airway clearance through secretion removal, and they can be used in routine physiotherapeutic care.

Abstract Introduction Coronary artery bypass grafting (CABG) surgery is associated with a decline in ventilatory muscle strength and lung function. Inspiratory muscle training (IMT) based on anaerobic threshold (AT) has been used to minimize the impact of CABG on these parameters, but the long-term impact is unknown. Objective To test the hypothesis that AT-based IMT improves inspiratory muscle strength and lung function even six months after CABG. Methods This is a randomized controlled clinical trial. In the preoperative period, maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), vital capacity (VC) and peak expiratory flow (PEF) rate were assessed. On the first postoperative day, patients were randomized into two groups: AT-based IMT (IMT-AT) (n=21) where the load was prescribed based on glycemic threshold and conventional IMT (IMT-C) (n=21), with load of 40% of MIP. Patients were trained during hospitalization until the day of discharge and were assessed at discharge and six months later. For within-group comparison, paired Student's t-test or Wilcoxon test was used, and independent Student's t-test or the Mann-Whitney test was used to analyze the different time points. A p<0.05 was considered significant. Results At six months after CABG surgery, statistical difference was found between the IMT-AT and the IMT-C groups in MIP (difference between the means of -5cmH2; 95% CI=- 8.21to-1.79) and VC (difference between the means of -2ml/kg;95%CI=-3.87to-0.13). No difference was found between groups in the other variables analyzed. Conclusion IMT-AT promoted greater recovery of inspiratory muscle strength and VC after six months of CABG when compared to conventional training.
ABSTRACT
Introdução: A fisioterapia na unidade de terapia intensiva (UTI) apresenta como objetivo utilizar estratégias de mobilização precoce a fim de reduzir o impacto da fraqueza muscular adquirida na UTI. Logo, este estudo apresenta como objetivo avaliar a efetividade de um plano de metas fisioterapêuticas para pacientes internados em uma Unidade de Terapia Intensiva.Métodos: Estudo de coorte retrospectivo e prospectivo comparativo realizado em uma UTI de um hospital público de Porto Alegre. Foram incluídos pacientes internados entre os meses de janeiro e junho de 2019, maiores de 18 anos e que tiveram alta da UTI. A coleta de dados foi realizada através de informações e relatório que constam no prontuário eletrônico utilizado na Instituição. Foi analisado o desfecho das metas estabelecidas na admissão para sentar fora do leito e deambular.Resultados: A maioria dos pacientes foi do sexo masculino (57,5%). A média de idade foi de 60,52 ± 17,64 anos. A maioria das metas estabelecidas, tanto para sentar fora do leito como para deambular, foram atingidas (89% e 86,9%, respectivamente). Houve correlação significativa entre o alcance de meta para deambulação e ganho de força muscular pelo escore MRC (p = 0,041) e ganho de força muscular quando comparada admissão e alta da UTI (p = 0,004).Conclusão: Este estudo observou que estabelecer metas para sentar fora do leito e deambular para pacientes internados em UTI é efetivo.
Introduction: Physiotherapy in the intensive care unit (ICU) aims to use early mobilization strategies in order to reduce the impact of muscle acquired weakness in the ICU. Therefore, this study aims to evaluate the effectiveness of a physiotherapeutic goal plan for patients admitted to an Intensive Care Unit. Methods: Retrospective and comparative prospective cohort study carried out in an ICU of a public hospital in Porto Alegre. Patients hospitalized between January and June 2019, over 18 years old and discharged from the ICU were included. Data collection was carried out through information and report contained in the electronic medical record used in the Institution. The outcome of goals established at admission for sitting out of bed and walking was analyzed. Results: Most patients were male (57.5%). The mean age was 63.2 ± 16.2 years. Most established goals, both for sitting out of bed and walking, were achieved (89% and 86.9%, respectively). There was a significant correlation between reaching the ambulation goal and muscle strength gain by the MRC score (p= 0.041) and muscle strength gain when comparing admission and discharge from the ICU (p = 0.004). Conclusion: This study observed that establishing goals for sitting out of bed and walking for ICU patients is effective.

OBJECTIVE: To translate, crossculturally adapt and evaluate the clinimetric properties of the Critical Care Functional Rehabilitation Outcome Measure for evaluating the functionality of patients admitted to intensive care units in Brazil. METHODS: The process of translation and cross-cultural adaptation involved the following steps: initial translation, synthesis, back-translation, expert committee review and pretesting. The intra- and interrater reliability and agreement were analyzed between two physical therapists who evaluated the same group of patients (n = 35). The evaluations were performed by each therapist independently and blinded to the score assigned by the other professional. The qualitative analysis was performed by the review committee, and the experts adapted and synthesized the Portuguese translation of the Critical Care Functional Rehabilitation Outcome Measure. RESULTS: There was agreement between the initial Brazilian translations of the Critical Care Functional Rehabilitation Outcome Measure scale. The conceptual, idiomatic, semantic and experimental equivalences between the original and translated versions were assessed, resulting in the final Brazilian version of the scale, called the Medida de Resultado da Reabilitação Funcional em Cuidados Intensivos. The evaluation of the clinimetric properties showed evidence of a high degree of agreement and reliability, as all had an intraclass correlation coefficient above 0.75. The overall intraclass correlation coefficient was 0.89. CONCLUSION: The translated version of the Critical Care Functional Rehabilitation Outcome Measure scale for assessing the functionality of patients admitted to an intensive care unit can be used reliably in Brazil following translation and cross-cultural adaptation to Brazilian Portuguese and presents evidence of excellent interrater reliability.

OBJECTIVES: To perform a systematic review with meta-analysis to verify the effects of multicomponent and resistance training on the physical performance in older adult residents in long-term care, as well as to compare these modalities. DESIGN: Systematic review with meta-analysis of randomized controlled trials. SETTING AND PARTICIPANTS: Older adults age over 60 years who are nursing home residents in long-term care. METHODS: Seven electronic databases (PubMed, Embase, Central, Web of Science, SportDiscus, LILACS, and SCIELO) were searched from their inception until May 1, 2022. The methodological quality was assessed using PEDro scale. Mean difference and 95% confidence interval were pooled using a random-effects model. The significance level established was P value of ≤.05 for all analyses. RESULTS: A total of 30 studies were included in the qualitative review (n = 1887, mean age 82.68 years and 70% female). Multicomponent training appeared in 19 studies and resistance training in 12 studies. Out of these, 17 studies were incorporated into the meta-analysis. Multicomponent training and resistance training showed statistically significant difference (P ≤ .05) in the physical performance of institutionalized older adults compared with the control groups (usual care); this was evaluated with the Short Physical Performance Battery (+1.2 points; +2 points), 30-second chair-stand (approximately +3 repetitions; both), and Timed Up and Go (-4 seconds on mean; both) tests. Comparisons between multicomponent and resistance training did not show statistically significant differences in any of the physical outcomes evaluated. CONCLUSIONS AND IMPLICATIONS: The studies provide evidence that both multicomponent training and resistance training may be effective in improving the physical performance of institutionalized older adults. Further studies with more representative sample numbers, an improvement in methodological quality, and a more specified prescription of the training used are necessary.

ABSTRACT
INTRODUCTION: Manual hyperinflation (MHI) or with a mechanical ventilator (VHI) are alternatives in bronchial hygiene therapy, in recent years several studies have emerged with the objective of verifying the effectiveness and safety of the techniques. OBJECTIVE: Systematically review and analyze the most recent studies in the literature on MHI and VHI, compare both techniques and demonstrate their effectiveness in bronchial hygiene therapy in mechanically ventilated patients. METHODS: We conducted this systematic review based on the PICO strategy and used the databases Ovid, LILACS, CINAHL, Pubmed and CENTRAL. Search, selection and analysis of randomized controlled trials on MHI, VHI or comparing both techniques. We performed a comparison on secretion elimination, static and dynamic compliance, oxygenation and clinical outcomes. The studies were analyzed by two independent evaluators. RESULTS: Nine articles were selected comparing MHI with usual care, demonstrating improved compliance in the MHI group, but with no impact on secretion removal. Four studies compared VHI with usual care, with three showing increased secretion elimination and compliance in the HVM group. Another four articles compared MHI with VHI but none of the studies showed superiority in terms of elimination of secretion and three studies found improvement in static compliance. CONCLUSION: Both techniques have proven to be effective alternatives to bronchial hygiene therapy.

Introdução: O suporte ventilatório é usado para o tratamento de pacientes com insuficiência respiratória aguda (IRpA) ou crônica agudizada. A ventilação não-invasiva (VNI) na IRpA pediátrica é amplamente usada em bebês prematuros e crianças, porém até a data atual os estudos têm sido escassos. Portanto, o objetivo do presente estudo foi determinar os fatores de risco associados à falha na VNI em uma unidade de terapia intensiva pediátrica.Métodos: Coorte retrospectiva a partir de prontuários de pacientes admitidos na unidade de terapia intensiva (UTI) Pediátrica de um Hospital de Caxias do Sul, entre maio de 2017 e outubro de 2019, que utilizaram VNI.Resultados: A incidência de falha na VNI foi de 33%. Asma (RR = 1,36; IC95% = 1,08-1,72), uso de VNI em pacientes pós-extubação (RR = 1,97; IC95% = 1,17-3,29), uso contínuo da VNI (RR = 2,44; IC95% = 1,18-5,05), encerramento à noite (RR = 2,52; IC95% = 1,53-4,14), modalidade final ventilação mandatória intermitente sincronizada (SIMV) (RR = 4,20; IC95% = 2,20-7,90), pressão expiratória positiva final (PEEP) no início da ventilação (6,8 ± 1,1; p < 0,01) e fração inspiratória de O2 (FIO2) final (53,10 ± 18,50; p < 0,01) foram associados à falha. Adicionalmente, a pressão arterial sistólica (PAS) inicial (118,68 ± 18,68 mmHg; p = 0,02), a frequência respiratória inicial (FR) (47,69 ± 14,76; p = 0,28) e final (47,54 ± 14,76; p < 0,01) foram associados a falha.Conclusão: A modalidade ventilatória final SIMV, demostra ser o melhor preditor de risco de falha, seguido do turno em que a VNI é finalizada, onde à noite existe maior risco de falha. Além disso, foram preditores de falha, porém com menor robustez, a pressão positiva inspiratória (PIP) final e a FR final.
Introduction: Ventilatory support is used for the treatment of patients with acutely chronic or acute respiratory failure (ARF). Noninvasive ventilation (NIV) in pediatric ARF is widely used in preterm infants and children, but studies to date have been limited. Therefore, the aim of the present study was to determine the risk factors associated with NIV failure in a pediatric intensive care unit.Methods: This retrospective cohort study was based on medical records of patients admitted to the pediatric intensive care unit of a hospital in Caxias do Sul, southern Brazil, between May 2017 and October 2019, who used NIV.Results: The incidence of NIV failure was 33%. Asthma (relative risk [RR] = 1.36; 95% confidence interval [CI] = 1.08-1.72), post-extubation use of NIV (RR = 1.97; 95% CI = 1.17-3.29), continuous use of NIV (RR = 2.44; 95% CI = 1.18-5.05), completion at night (RR = 2.52; 95% CI = 1.53-4.14), final mode synchronized intermittent mandatory ventilation (SIMV) (RR = 4.20; 95% CI = 2.20-7.90), positive end-expiratory pressure at the beginning of ventilation (6.8 ± 1.1; p < 0.01), and final fraction of inspired oxygen (53.10 ± 18.50; p < 0.01) were associated with failure. Additionally, initial systolic blood pressure (118.68 ± 18.68 mmHg; p = 0.02), initial respiratory rate (IRR) (47.69 ± 14.76; p = 0.28), and final respiratory rate (47.54 ± 14.76; p < 0.01) were associated with failure.Conclusion: The final ventilatory mode SIMV proves to be the best failure risk predictor, followed by the shift in which NIV is completed, as there is a greater risk of failure at night. In addition, final positive inspiratory pressure and final respiratory rate were less robust predictors of failure.

Introdução: A utilização da ventilação não invasiva (VNI) é importante no tratamento de pacientes críticos internados em unidades de terapia intensiva (UTI), apresentando resultados significativos quando avaliada e instituida no momento adequado. Os benefícios da VNI são evidentes em diferentes etiologia, favorecendo a evolução clínica dos pacientes e diminuindo tempo de internação. O uso da VNI como resgate apresenta resultados desfavoráveis, porém o uso de VNI preventiva ou, facilitadora parece promissor neste cenário. Objetivo: Avaliar as indicações para utilização da VNI em pacientes críticos, identificar, e analisar os desfechos da resposta à VNI, o tempo de internação, e outros benefícios para estabelecer possíveis desfechos nos pacientes críticos internados nesta unidade. Métodos: Estudo de coorte retrospectivo, realizado através de análise de prontuários de pacientes maiores de 18 anos, ambos os sexos, admitidos na UTI adulto e submetidos a VNI, no período de agosto de 2018 a agosto de 2019. Resultados: Foram incluídos 114 pacientes, 57% do sexo masculino, com idade de 69 ±13 anos, que ficaram internados por 13,2 ± 11,8 dias, apresentando uma pontuação de SAPS 3 59±14 pontos, sendo a IRpA o motivo do uso de VNI mais frequente, representando 64,9% da amostra, seguido da VNI de forma preventiva após extubação (17,5%). Obtivemos um total de 66,9% de sucesso na utilização da VNI. Conclusão: A utilização da VNI no perfil dos pacientes críticos internados, apresentaram sucesso para o uso na maioria dos casos, mostrando melhores desfechos clínicos e propiciando diminuir o tempo de internação na UTI, e alta desta unidade.

Introduction: The use of noninvasive ventilation (NIV) is important in the treatment of critically ill patients admitted to the intensive care unit (ICU), showing significant results when evaluated and introduced at the appropriate time. The benefits of NIV are evident in different etiologies by favoring the clinical outcome of patients and reducing the length of hospital stay. The use of NIV as a rescue therapy has produced unfavorable results. However, the use of preventive or facilitating NIV seems promising in this scenario. Objective: To evaluate indications for the use of NIV in critically ill patients and to identify and analyze the outcomes of NIV response, length of hospital stay, and other benefits in order to establish possible outcomes in critically ill ICU patients. Methods: This was a cohort study with a retrospective review of the medical records of patients aged 18 years or older, of both sexes, who were admitted to the adult ICU and received NIV from August 2018 to August 2019. Results: A total of 114 patients were included, 57% were men and the mean age was 69 (SD, 13) years. The mean length of hospital stay was 13.2 (SD, 11.8) days, and SAPS score was 3.59 (SD, 14). Acute respiratory failure was the main reason for NIV use, accounting for 64.9% of cases, followed by preventive NIV after extubation (17.5%). The success rate of NIV use was 66.9%. Conclusions: The use of NIV in critically ill ICU patients was successful in most cases, leading to improved clinical outcomes and reduced length of ICU stay, with faster discharge from this unit.

A bronquiolite é uma infecção viral que pode levar a insuficiência ventilatória, nestes casos a aplicação de ventilação não invasiva é uma opção ao tratamento convencional. O objetivo deste estudo é identificar o desfecho da aplicação de ventilação não invasiva em crianças com bronquiolite. Trata-se de uma revisão da literatura, com busca de artigos nas bases de dados Biblioteca Virtual em Saúde, Cochrane Library, PEDro, Pubmed, Scielo e Science Direct, sem restrição de período, a partir das palavras chave Noninvasive ventilation AND Bronchiolitis. De um total de 1.192 artigos encontrados, 11 foram inclusos no presente estudo, quatro abordaram o desfecho relacionado à aspectos clínicos gerais (aumento no uso de VNI; menor tempo de internação; redução da frequência respiratória e fração inspirada de oxigênio) e sete relataram o índice de sucesso ou falha, e apesar da diferença entre as médias (sucesso 88,5 versus falha 15,1) não houve diferença significativa. Conclui-se que o desfecho de falha tem alta prevalência (11,5%), apesar disso, os estudos encontraram diferentes benefícios advindos do incremento na aplicação de VNI (redução da necessidade de ventilação mecânica invasiva, menor tempo de permanência em UTI, redução da mortalidade, melhora da frequência respiratória e da fração inspirada de oxigênio).

Bronchiolitis is a viral infection that can lead to ventilatory failure. In such cases, the application of noninvasive ventilation (NIV) is an alternative to conventional treatment. The aim of this study is to identify the outcome of the application of NIV in children with bronchiolitis. This is a literature review whose search for articles included the Virtual Health Library, Cochrane Library, PEDro, PubMed, SciELO, and Science Direct databases, with no date restriction, based on the keywords Noninvasive ventilation AND Bronchiolitis. Of a total of 1192 articles found, 11 were included in the present study. Four addressed the outcome related to general clinical aspects (increased use of NIV, shorter hospital stay, and reduced respiratory rate and inspired oxygen fraction) and seven reported the success or failure rate. Despite the difference between the means (success 88.5 versus failure 15.1) there was no significant difference. In conclusion, the failure outcome has a high prevalence (11.5%); however, studies have found different benefits arising from the increased application of NIV (reduced need for invasive mechanical ventilation, shorter intensive care unit stay, reduced mortality, and improved respiratory rate and inspired oxygen fraction).

INTRODUÇÃO: Em situações emergenciais, se torna crucial o manejo adequado das vias aéreas, pois falhas neste processo contribuem consideravelmente para piores desfechos clínicos. OBJETIVO: comparar a utilização do tubo endotraqueal e da máscara laríngea no atendimento pré- -hospitalar em relação aos desfechos hospitalares tais como tempo de ventilação mecânica, tempo de permanência na UTI e taxa de óbito. MATERIAIS E MÉTODOS: estudo observacional retrospectivo, desenvolvido no Hospital Santa Cruz, Rio Grande do Sul. Foram incluídos pacientes maiores de 18 anos, de ambos os sexos, que foram atendidos pelo SAMU durante o atendimento pré-hospitalar, e após o encaminhados para o Pronto Atendimento ou Ambulatório do Hospital Santa Cruz. As variáveis analisadas foram extraídas dos prontuários médicos dos indivíduos selecionados. RESULTADOS: foram analisados 27 indivíduos, maioria do sexo masculino, com média de idade de 46,5±22 anos, sendo a causa predominante do atendimento pré-hospitalar o politraumatismo. Ao compararmos os pacientes que utilizaram tubo endotraqueal com os que utilizaram máscara laríngea, não foram observadas diferenças significativas em relação ao tempo de atendimento pré-hospitalar. Na fase intra-hospitalar, observamos diferença significativa em relação ao tempo de ventilação mecânica e tempode internação na UTI, não sendo o mesmo observado em relação a taxa de óbito. CONCLUSÃO: Os pacientes submetidos a utilização da máscara laríngea no atendimento pré-hospitalar apresentaram menor tempo de ventilação mecânica e menor tempo de internação na UTI, em relação aos pacientes intubados com tubo endotraqueal.
INTRODUCTION: In emergency situations, proper management of the airways becomes crucial, because flaws in this process contribute considerably to worse clinical outcomes. OBJECTIVE: To compare the use of the endotracheal tube and laryngeal mask in prehospital care in relation to hospital outcomes such as mechanical ventilation time, length of stay in the ICU and death rate. MATERIALS AND METHODS: a retrospective observational study, developed in a Hospital Santa Cruz, Rio Grande do Sul. Patient records were used from the Emergency Mobile Service (SAMU) of Santa Cruz do Sul, sent to the Emergency Department or Ambulatory of Santa Cruz Hospital. RESULTS: 27 individuals, mostly males, with an average age of 46.5 ± 22 years, were analyzed, being the predominant cause of pre-hospital care the polytrauma. When comparing the patients who used the endotracheal tube with those who used laryngeal mask, no significant differences were observed in relation to the time of prehospital care. In the in-hospital phase, we observed a significant difference in relation to the time of mechanical ventilation and length of stay in the ICU, and the same was not observed in relation to the death rate. CONCLUSION: The patients submitted to the use of the laryngeal mask in the pre-hospital care presented a shorter time of mechanical ventilation and a shorter time of hospitalization in the ICU than the patients intubated with an endotracheal tube.

Introdução. Pacientes com insuficiência cardíaca (IC) portadores de apneia obstrutiva do sono (AOS) tem taxas de morbi mortalidade elevados e o tratamento com a pressão positiva contínua nas vias aéreas (CPAP) pode reduzir estes riscos. Objetivo geral. Realizar uma revisão sistemática de ensaios clínicos randomizados sobre os efeitos da terapia por CPAP em pacientes com IC portadores de AOS. Fontes de informação. Pesquisamos as bases de dados eletrônicas PubMed, Embase, Web of Science e Lilacs nos últimos 10 anos, sem limites de linguagem. Critérios de elegibilidade. Ensaios clínicos randomizados, estudos de pacientes com IC apresentando fração de ejeção do ventrículo esquerdo (FEVE) reduzida (<50%) portadores de apneia obstrutiva do sono e que fossem tratados com CPAP. Resultados. A FEVE aumentou consideravelmente nos grupos que receberam a terapia por CPAP (média basal: 30,6%; média pós CPAP: 36,7%), assim como a saturação de oxigênio (SaO2) (média basal: 94%; média pós CPAP: 95,3%) e houve redução no índice de apneia/hipopneia (média basal: 39,6; média pós CPAP: 12,3). Conclusões. Nossa revisão sistemática de ensaios clínicos randomizados confirma que a terapia por CPAP em pacientes com IC portadores de AOS melhora variáveis preditoras de morbi mortalidade.

Introdução: A presença da via aérea artificial, associada com a imobilidade no leito, resulta em um déficit na desobstrução das vias aéreas em pacientes sob ventilação mecânica (VM). Tal condição contribui para o desenvolvimento de quadros de hipoxemia e/ou infecções respiratórias, aumentando o trabalho respiratório e também as falhas de extubação. Objetivo: Comparar os efeitos da utilização do insuflador-exsuflador mecânico e da manobra PEEP-ZEEP em relação à mecânica respiratória em pacientes ventilados mecanicamente por tempo prolongado. Métodos: Ensaio clínico randomizado cruzado, incluindo pacientes em ventilação mecânica por mais de 10 dias. Os pacientes foram randomizados para receber a aplicação do insuflador-exsuflador mecânico e da manobra PEEP-ZEEP. Foram mensuradas complacência pulmonar, estática e dinâmica, e resistência pulmonar antes e após a aplicação de cada técnica. Resultados: Foram incluídos 22 pacientes. Na análise intragrupos observa-se aumento significativo na complacência dinâmica e complacência estática após a aplicação de ambas as técnicas. A resistência pulmonar variou significativamente apenas após a aplicação do insuflador-exsuflador mecânico. Não foram observadas diferenças significativas na análise intergrupos. Conclusão: O insuflador-exsuflador mecânico e a manobra de PEEP-ZEEP demonstraram ter efeito positivo tanto sobre a complacência estática quanto a dinâmica. Entretanto, a resistência pulmonar aumentou após a aplicação do insuflador-exsuflador mecânico. (AU)
Introduction: The presence of the artificial airway associated with immobility in the bed results in a deficit in the clearance of the airways in patients under mechanical ventilation (MV). This condition contributes to the development of hypoxemia and/or respiratory infections, increasing respiratory work and also extubation failures. Objective: To compare the effects of the use of mechanical insufflation-exsufflation and PEEP-ZEEP maneuver in relation to respiratory mechanics in patients on prolonged mechanical ventilation. Methods: Randomized cross-over trial, including patients on mechanical ventilation for more than 10 days. The patients were randomized to receive the application of mechanical insufflator-exsuflator and PEEP-ZEEP maneuver. Pulmonary compliance, static and dynamic, and pulmonary resistance were measured before and after the application of each technique. Results: 22 patients were included. In the intragroup analysis we observed a significant increase in the dynamic compliance and static compliance after the application of both techniques. Pulmonary resistance varied significantly only after application of the mechanical insufflation-exsufflation. No significant differences were observed in the inter-group analysis. Conclusion: The mechanical insufflator-exsuflator and the PEEP-ZEEP maneuver were shown to have a positive effect on both static and dynamic complacency. However, pulmonary resistance increased after the application of the mechanical insufflation-exsufflation.(AU)

OBJECTIVE: Stroke often leads to abnormalities in muscle tone, posture, and motor control that may compromise voluntary motor function, thus affecting the motor control required for maintaining the synergy of both peripheral and respiratory muscles. To evaluate respiratory muscle strength, pulmonary function, trunk control, and functional independence in patients with stroke and to correlate trunk control with the other variables. METHODS: This was a cross-sectional study of patients diagnosed with stroke. We assessed respiratory muscle strength, trunk control as assessed by the Trunk Impairment Scale, spirometric variables, and the Functional Independence Measure. RESULTS: Forty-four patients were included. Pulmonary function and respiratory muscle strength were significantly lower than predicted for the study population, and the mean Trunk Impairment Scale score was 14.3 points. The following significant correlations were found between the variables: trunk control vs. maximal inspiratory pressure (r = 0.26, p < 0.05); trunk control vs. forced vital capacity (r = 0.28, p < 0.05); trunk control vs. forced expiratory volume in one second (r = 0.29, p < 0.05), and trunk control vs. the Functional Independence Measure (r = 0.77, p < 0.05). CONCLUSION: The present study showed that respiratory muscle strength, pulmonary function, functional independence, and trunk control are reduced in patients diagnosed with stroke.

OBJECTIVE: To evaluate the pulmonary alterations of animals with Hepatopulmonary Syndrome (HPS) submitted to Biliary Duct Ligature (BDL), as well as the antioxidant effect of Melatonin (MEL). METHODS: Sixteen male Wistar rats, divided into four Sham groups: BDL group, Sham + MEL group and BDL + MEL. The pulmonary and hepatic histology, lipoperoxidation and antioxidant activity of lung tissue, alveolar-arterial O2 difference and lung / body weight ratio (%) were evaluated. RESULTS: When comparing the groups, could be observed an increase of vasodilation and pulmonary fibrosis in the BDL group and the reduction of this in relation to the BDL + MEL group. It was also observed significant changes in the activity of catalase, ApCO2, ApO2 in the LBD group when compared to the other groups. CONCLUSION: The use of MEL has been shown to be effective in reducing vasodilation, fibrosis levels and oxidative stress as well as gas exchange in an experimental HPS model.

RESUMO Acidente vascular cerebral (AVC) frequentemente leva a anormalidades no tônus muscular, postura e controle motor que podem comprometer a função motora voluntária, afetando o controle motor necessário para manter a sinergia dos músculos periféricos e respiratórios. Objetivo Avaliar a força muscular respiratória, a função pulmonar, o controle do tronco e a independência funcional em pacientes com AVC e correlacionar o controle do tronco com as demais variáveis. Métodos Este foi um estudo transversal, incluindo pacientes diagnosticados com AVC. Avaliamos a força muscular respiratória, o controle do tronco avaliado pela escala de comprometimento de tronco, as variáveis espirométricas e a medida de independência funcional. Resultados Quarenta e quatro pacientes foram incluídos. A função pulmonar e a força muscular respiratória foram significativamente menores do que o previsto para a população estudada, e o escore médio do escala de comprometimento de tronco foi de 14,3 pontos. As seguintes correlações significativas foram encontradas entre as variáveis: controle do tronco vs. pressão inspiratória máxima (r = 0,26, p <0,05); controle do tronco vs capacidade vital forçada (r = 0,28, p <0,05); controle do tronco versus volume expiratório forçado no primeiro segundo (r = 0,29, p <0,05) e controle do tronco vs. medida de independência funcional (r = 0,77, p <0,05). Conclusão O presente estudo demonstrou que a força muscular respiratória, a função pulmonar, a independência funcional e o controle do tronco estão diminuídos em pacientes diagnosticados com AVC.
