Does Obstructive Sleep Apnea (OSA) Increase the Risk of Post-Operative Respiratory Complications after Bariatric Surgery?
Open accessAbstract
Background: OSA affects up to quarter of general population. It is associated with morbid obesity with a higher morbidity and mortality rates. STOP Bang questionnaire is a validated method for OSA screening. OSA patients are at high risk of developing airway obstruction, cardiac events, congestive heart failure, stroke and desaturation post operatively. The aim of this study is to evaluate adverse respiratory events in patients undergoing bariatric surgery in relation to risk of OSA using Stop Bang questionnaire. Methods: This prospective double cohort study was conducted in Tanta University Hospital from Marchto August 2017. During the preoperative assessment, STOP-BANG questionnaire was performed. After extubation, patients were transferred to PACU unit. Respiratory complications were assessed thereafter. Based on STOP-BANG score, patients were divided into two groups, high risk of OSA with STOP-BANG > 3 (Group I) and low risk of OSA with STOP-BANG Results: 104 patients were included in this study. Group I had more comorbidities in the form of CAD (15% versus 2%, P 0.001). Higher number of respiratory complications was noted in high-risk group (31 patients, 59%) compared to (24 patients, 46%) in group II yet, it was not significant. Conclusion: Obese patients with STOP-BANG score > 3 undergoing bariatric surgery are associated with hypertension, dyslipidemia, CAD, and renal insufficiency. High-risk OSA obese patients are at higher risk of developing respiratory compilations like inability to breathe deeply and hypoxia in postoperatively.

Meta-analysis of observational studies suggested that patients with obstructive sleep apnea or related disorders were more likely to sustain atrial fibrillation (OR 1.51, 95% CI 1.36 to 1.69).
“Meta-analysis of observational studies suggested that patients with obstructive sleep apnea or related disorders were more likely to sustain atrial fibrillation (OR 1.51, 95% CI 1.36 to 1.69) or hypoxemia (WMD − 3.8%, 95% CI − 5.4% to − 2.2%) [45–59].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
