Is Incentive Spirometry Superior to Standard Care in Postoperative Cardiac Surgery on Clinical Outcomes and Length of Hospital and Intensive Care Unit Stay? A Systematic Review with Meta-Analysis.

INTRODUCTION: Cardiac surgery is a frequent surgical procedure and may present a high risk of complications. Among the prophylactic strategies studied to decrease the rates of negative outcomes, respiratory care seems to reduce pulmonary complications. Incentive spirometry (IS) is a low-cost, respiratory exercise technique, used for the prevention and treatment of postoperative pulmonary complications (PPC). The aim of this review was to evaluate whether IS is superior to respiratory care, mobilization exercises, and noninvasive ventilation on PPC, and clinical outcomes. METHODS: Systematic review. Medical Literature Analysis and Retrieval System Online (or MEDLINE®), Embase®, Cochrane Central Register of Controlled Trials (or CENTRAL), Physiotherapy Evidence Database (or PEDro), Cumulative Index of Nursing and Allied Health (or CINAHL®), Latin American and Caribbean Health Sciences Literature (or LILACS), Scientific Electronic Library Online (or SciELO), Allied, Scopus®, and OpenGrey databases, clinical trial registration sites, conferences, congresses, and symposiums were searched. RESULTS: Twenty-one randomized trials and one quasi-randomized trial (1,677 participants) were included. For partial pressure of oxygen (PaO2), IS was inferior to respiratory care (mean difference [MD] -4.48; 95% confidence interval [CI] -8.32 to -0.63). Flow-oriented IS was inferior to respiratory care on PaO2 (MD -4.53; 95% CI -8.88 to -0.18). However, compared to respiratory care, flow-oriented IS was superior on recovery vital capacity. CONCLUSIONS: This meta-analysis revealed that IS was not superior to standard respiratory care for PPCs and clinical outcomes, therefore its use should not be widely recommended until further studies with high quality be performed to ensure this clinical guidance.

A distância entre o domicílio e o centro de reabilitação não influencia a adesão ao programa de reabilitação pulmonar: um estudo retrospectivo / Distance from home to rehabilitation center did not influence adherence to pulmonary rehabilitation program: a retrospective study

Background: Adherence to treatment is critical when dealing with chronic diseases. One of the difficulties in maintain long-term adherence is the distance from home to rehabilitation center. Objective: To determine the influence of the distance from subjects' residence to rehabilitation center on adherence of a 12-week pulmonary rehabilitation program in chronic respiratory disease. Methods: This retrospective study analyzed patients' medical records with chronic respiratory diseases from a pulmonary rehabilitation center. Driving distance between patients' home and rehabilitation center was calculated with Google maps. The home-rehabilitation center distances were classified in three levels: up to 10, 10-30 and more than 30 km. Results: 280 medical records from patients with chronic pulmonary diseases with medical indication to follow the pulmonary rehabilitation program were found and 148 medical records were included in our study. Out of them, the majority (n = 93) had chronic obstructive pulmonary disease (COPD). Seventy percent of patients lived up to 10 km, 24% lived between 10 and 30 km and 6% lived more than 30 km. No difference in adherence was found comparing the three groups based on the distance from home to rehabilitation center. Conclusion: In this study, distance between home and rehabilitation center did not influence adherence to pulmonary rehabilitation program. (AU)

Influência da composição corporal durante a hospitalização sobre a função pulmonar e força da musculatura inspiratória em pacientes com COVID-19: estudo transversal / Influence of body composition during hospitalization on lung function and inspiratory muscle strength in patients with COVID19: cross-sectional study

Introdução: Cerca de 31% dos pacientes hospitalizados com COVID-19 perdem mais de 5% de seu peso inicial, levando a fraqueza muscular. Portanto, a composição corporal tornou-se foco de investigação, para estimar comprometimento pulmonar, força da musculatura inspiratória e mortalidade. Objetivos: Investigar se a perda de peso e a composição corporal de pacientes internados com COVID-19 influenciam na função pulmonar e na força muscular inspiratória após alta hospitalar. Métodos: Estudo transversal. Pacientes adultos foram avaliados após internação por COVID-19. Os desfechos avaliados foram função pulmonar, pressão inspiratória máxima (Pimáx), composição corporal e mortalidade. As correlações entre as variáveis foram estimadas pelo Coeficiente de Correlação de Pearson. Resultados: A capacidade Vital Forçada (CVF) foi correlacionada com perda de peso, massa muscular esquelética, massa magra, perna esquerda e massa livre de gordura; o volume expiratório forçado no primeiro segundo (VEF1) correlacionou-se apenas com a perda de peso; e a Pimáx foi correlacionada com massa muscular esquelética, massa magra, perna esquerda, perna direita e massa livre de gordura. Conclusão: Observou-se correlação moderada entre CVF e as variáveis de composição corporal analisadas, exceto massa magra da perna esquerda; entre VEF1 e perda de peso; e entre Pimáx e as variáveis de composição corporal analisadas, exceto perda de peso.
