Analysis of Factors Influencing Extended Post Anesthesia Care Unit Length of Stay (PACU-LOS) in Obese Patients Undergoing Laparoscopic Sleeve Gastrectomy

ASA III classification, preexisting OSAS, and post-extubation hypoxemia independently predict extended PACU-LOS in patients undergone laparoscopic sleeve gastrectomy. These findings underscore the imperative for preoperative risk stratification using standardized scoring systems, protocolized post-extubation oxygenation strategies, and resource allocation for high-dependency monitoring in at-risk patients. While this study establishes predictors of extended PACU-LOS, its correlation with postoperative complications warrants dedicated future investigation.
