Preoperative Inspiratory Muscular Training to Prevent Postoperative Hypoxemia in Morbidly Obese Patients Undergoing Laparoscopic Bariatric Surgery. A Randomized Clinical Trial

摘要

Background Morbidly obese patients show an increased risk of postoperative hypoxemia and pulmonary complications when compared with normal weight subjects. The purpose of this study was to determine the effects of preoperative inspiratory muscular training (IMT) on postoperative arterial oxygenation in morbidly obese patients submitted to laparoscopic bariatric surgery.
