Ventilatory muscle strength and quality of life in obese patients undergoing bariatric surgery. Prelimianry results

Abstract

Introduction Obesity is one of the public health problems more relevant in modern society, leading to a series of changes in mechanical ventilation. Obesity treatment is aimed at improving the health and quality of life. Materials and methods The study included 13 female patients, obese grade III, recruited from two bariatric surgery services and referred to the Sleep Laboratory at the Nove de Julho University. Inclusion criteria included patients who were obese grade III (BMI ⩾ 40 ) or grade II (BMI 35.0–39.9), age between 18 and 65years, accepting voluntarily to participate in the study by reading and signing the informed consent form. Results Mean age was 40.08 ± 9.86, after bariatric surgery the mean body mass index was 36.91 ± 6.67, with p =0.004 and maximum inspiratory pressures were 84.12 ± 9.36 and 82.36 ± 12.21 the maximum expiratory, with a p ?0.001 and p ?0.001 respectively. With the BAROS questionnaire there was an report of good to excellent response to surgery in terms of quality of life in 75% of patients. Conclusion After bariatric surgery an optimization in maximum inspiratory and expiratory pressures was observed. The BAROS questionnaire is standardized and easily applied to evaluate the results after bariatric surgery.
