Results of respiratory parameters in morbidly obese patientes with obstructive sleep apnoea after bariatric surgery
2011
Background: Bariatric surgery (BS) is an effective treatment for morbidly obese patients. Our aim is to analyze the sleep breathing parameters after BS in patients with obstructive sleep apnoea (OSA) and the differences between patients who corrected the disorders and patients who did not Methods: Morbidly obese and diagnosed of OSA patients, who underwent BS. We analyzed weight-loss and sleep parameters before and after BS. We consider improvement a decrease of 50% in the AHI or AHI after BS ≤10 Results: 52 patients, 41 (79%) women, 11 men (21%), mean age 44.24±9.78 years. 48 (92%) with preBS AHI >10, 4 cases (8%) with SaO2 disorders. 39 cases with AHI postBS ≤10 y 13 cases with IAH >10. 49/52 cases (94%) improved or solved their OSA. In 3 cases the AHI postBS was >10, but improved from severe to mild. 4 cases with SaO2 disorders and AHI 30 Conclusions: 1. BS solved completely the OSA in most of the patients (40/52, 77%) and improved it in all of them. 2. No statistical difference was observed in weight loss before and after BS. 3. Patients with an AHI postBS >10 had a high preBS AHI (mean 66.6), significantly higher than patients with AHI
