Ventilator hyperinflation associated with flow bias optimization in the bronchial hygiene of mechanically ventilated patients.

BACKGROUND: Ventilation configurations are of great clinical importance for adequate outcomes in mechanically ventilated patients, and they may even be used as specific physical therapy techniques. OBJECTIVES: To compare the effectiveness of lung hyperinflation through mechanical ventilation (HMV) with HMV plus flow bias optimization regarding respiratory mechanics, hemodynamics, and volume of secretion. METHODS: Patients mechanically ventilated > 24 h were included in this randomized crossover clinical trial. The following techniques were applied: HMV alone (control group) and HMV plus flow bias optimization (intervention group). RESULTS: The 20 included patients underwent both techniques, totaling 40 collections. A total of 52 % were women, the mean age was 60.8 (SD, 15.7) years, and the mean mechanical ventilation time was 4.3 (SD, 3.0) days. The main cause of mechanical ventilation was sepsis (44 %). Expiratory flow bias in optimized HMV was higher. than conventional HMV (p < 0.001). The volume of tracheal secretions collected was higher during optimized than conventional HMV. (p = 0.012). Significant differences in peak flow occurred at the beginning of the technique and a there was a significant decrease in respiratory system resistance immediately and 30 min after applying the technique in the intervention group. CONCLUSIONS: The volume of tracheal secretions collected was higher during optimized HMV, and, HMV with flow bias optimization resulted in lower respiratory system resistance and flow peaks and produced expiratory flow bias.

Evaluation and Comparison of Respiratory Muscular Strength, Functionality, and Pelvic Floor in the Immediate Postpartum of Normal and Cesarean Birth.

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.

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.

Effects of ventilator hyperinflation on pulmonary function and secretion clearance in adults receiving mechanical ventilation: A systematic review with meta-analysis.

INTRODUCTION: It is important to clarify the effect of ventilator hyperinflation(VHI) on pulmonary function and secretion clearance in adults receiving mechanical ventilation(MV). There is no published meta-analysis on the effects VHI on pulmonary function and secretion clearance in adults receiving MV. Objective Analyze the published randomized clinical trials(RCTs) that investigated the effects of VHI on pulmonary function and secretion clearance in adults receiving MV, comparing VHI with isolated aspiration, VHI with manual hyperinflation(MHI), VHI +vibrocompression(VB) versus VB and VHI+VB versus isolated aspiration. METHODS: The following databases PubMed, LILACS, EMBASE, SciELO, PEDro database and Cochrane Central Register of Controlled Trials (CENTRAL) were consulted up to December 2021. Secretion clearance, static and dynamic compliance of the respiratory system(Cstat and Cdyn), airway resistance(Raw) and oxygenation outcomes were evaluated. RESULTS: Thirteen studies met the study criteria, but only 12 studies were included on meta-analysis. There was no difference between VHI versus isolated aspiration for amount of secretions removed(0.41 SMD; 95% CI: -0.08 to 0.89; n=270), VHI versus MHI(0.51 grams; 95% CI: -0.08 to 1.11; n=256), VHI+VB versus VB(0.31 grams; 95% CI: -0.42 to 1.05; n=130) and VHI+VB versus isolated aspiration(0.54 grams; 95% CI: -0.06 to 1.14; n=132). There was difference for VHI versus isolated aspiration to Cstat (4.77 ml/cm H2O; 95% CI: 2.41 to 7.14; n= 136). CONCLUSION: Taking into account all studies included in meta-analysis, no evidences was found that VHI was effective in increasing the amount of secretions removed, Cdyn and oxygenation, but VHI seems to show a slight improvement in Cstat when compared to isolated aspiration. No evidence was found that VHI was effective in increasing the amount of secretions removed, Cdyn and oxygenation, but VHI seems to show a slight improvement in Cstat when compared to isolated aspiration.

Avaliação da independência funcional e da qualidade de vida após a alta da unidade de terapia intensiva: um estudo do coorte prospectivo / Evaluation of functional independence and quality of life after discharge of intensive care unit: a prospective cohort study

INTRODUÇÃO: Os pacientes criticamente doentes podem sofrer alterações funcionais, sociais e mentais, incluindo deficiência de conhecimento, memória e concentração após a admissão na unidade de terapia intensiva (UTI) e alta hospitalar. Apesar do conhecimento sobre o impacto da internação hospitalar na funcionalidade e qualidade de vida, ainda há pouco reconhecimento na literatura sobre este impacto a longo prazo. OBJETIVO: Verificar a independência funcional e a qualidade de vida (QOL) em pacientes acima de 1 ano após a alta da Unidade de Tratamento Intensivo (UTI). MÉTODOS: Este é um estudo de coorte prospectivo, foram admitidos na UTI e sob ventilação mecânica por mais de 48 horas, até 24 horas após a alta da UTI, acima de 18 anos de idade, de ambos os sexos e que concordaram em participar do estudo. Foram excluídos aqueles com sequelas neurológicas e traumas recorrentes que impossibilitavam a avaliação funcional. As variáveis independência funcional (Medida de Independência Funcional - FIM) e QOL foram medidas utilizando o questionário do formulário curto 36 (SF-36) no momento da alta da UTI (período I), 30 dias (período II), e 1 ano após (período III). RESULTADOS: 33 pacientes foram incluídos no estudo com uma idade média de 49,13±16,3 anos, e a principal causa de hospitalização foi distúrbios neurológicos, dos quais 5(14,70%) morreram, e dois não completaram as avaliações, resultando em um total de 26 pacientes avaliados 1 ano após a alta. A duração da internação na UTI (dias) foi de 16 (7 - 22) e o tempo de ventilação mecânica (dias) foi de 8,5 (2 - 13). Dez pacientes lá foram diagnosticados com sepse. Foram encontrados os seguintes valores nesses três momentos para as variáveis IF (I-51 [47-64,5]; II-80[59,5-108]; III104[82,8-123]) e QOL(I-67,4[57,3-81,1]; II-80,2[70,1-99,2]; III-93,5[88,5-96,5]). A independência funcional e QOL aumentou significativamente entre os momentos II e III, em comparação com os momentos I (p <0,05), sem diferença na comparação do período II em relação ao III. CONCLUSÃO: Os pacientes recuperam sua funcionalidade e qualidade de vida após trinta dias de alta da UTI. Entretanto, a funcionalidade e a qualidade de vida deste paciente não mudam após 1 ano de alta da UTI em relação ao período de 30 dias após a alta da UTI.

INTRODUCTION: Critically ill patients may experience functional, social, and mental changes, including impaired cognition, memory, and concentration after admission to the intensive care unit (ICU) and hospital discharge. Despite the knowledge about the impact of the hospital stay on functionality and quality of life, there is still little recognition in the literature of this impact in the long term. OBJECTIVE: To verify functional independence and quality of life (QOL) in patients over 1 year after discharge from the Intensive Care Unit (ICU). METHODS: This is a prospective cohort study, were admitted to the ICU and under mechanical ventilation for more than 48 hours, up to 24 hours after discharge from the ICU, over 18 years of age, of both sexes and who agreed to participate in the study. Those with neurological sequelae and recurrent trauma that made functional assessment impossible were excluded. Functional independence (Functional Independence Measure-FIM) and QOL variables were measured using the Short Form 36 questionnaire (SF-36) at the time of discharge from the ICU (period I), 30 days (period II), and 1 year after (period III). RESULTS: 33 patients were included in the study with a mean age of 49.13±16.3, and the main cause of hospitalization was neurological disorders, of which 5 (14.70%) died, and two did not complete the evaluations, resulting in a total of 26 patients evaluated 1 year after discharge. The length of ICU stay (days) was 16 (7 - 22) and the Mechanical Ventilation time (days) was 8,5 (2 - 13). Ten patients there were diagnosed with sepsis. The following values over these three moments were found for the variables IF (I-51 [47­64.5]; II-80[59.5­108]; III-104[82.8-123]) and QOL(I­67.4[57.3­81.1]; II-80.2[70.1­99.2]; III­93.5[88.5­ 96.5]). Functional independence and QOL increased significantly between moments II and III compared to moments I (p <0.05), with no difference, when comparing period II in relation to III. CONCLUSION: Patients recover their functionality and quality of life after thirty days of discharge from the ICU. However, this patient's functionality and quality of life do not change after 1 year of discharge from the ICU in relation to the period of 30 days after discharge from the ICU.

Correlation between trunk control, respiratory muscle strength and spirometry in patients with stroke: an observational study.

INTRODUCTION: Stroke is the main cause of chronic disability in adults, and the effect of a stroke on the respiratory system depends on the structures affected by the lesion. OBJECTIVES: To evaluate the correlation between trunk control, respiratory muscle strength and pulmonary function in individuals who suffered stroke. METHODS: Observational, quantitative and descriptive study. Twenty-three patients who had a clinical diagnosis of ischaemic or haemorrhagic stroke. The trunk control was assessed through the Trunk Impairment Scale (TIS), and the respiratory muscle strength was assessed by manovacuometry by measuring the maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). For pulmonary function analysis, we measured forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF) and the Tiffeneau index (TIFF) through spirometry. RESULTS: A consistent and statistically significant correlation was found between TIS and PEF (r = 0.489, p = 0.024) and between TIS and EPmax (r = 0.517, p = 0.016). No relation was found between the other variables of pulmonary function and TIS. CONCLUSION: This study demonstrated that there is a relation between trunk control and respiratory muscular strength, especially concerning the expiratory muscles. However, there seems to be no relation between trunk control and pulmonary function in this series of individuals who suffered stroke.
