Analysis of risk factors for delayed leaving postanesthesia care unit after bariatric surgery in obese patients
Objective To analyze the risk factors for delayed leaving postanesthesia care unit(PACU)after laparoscopic bariatric surgery in obese patients.Methods The clinical data of 1 220 obese patients underwent laparoscopic bariatric surgery were analyzed retrospectively,of whom 163 cases had the PACU stay time of ≥120 minutes(group A)and 1 057 cases had the PACU stay time of＜120 minutes(group B).Propensity score matching and multivariate logistic regression were used to analyze the risk factors of delayed leaving PACU after laparoscopic bariatric surgery in obese patients.Results Propensity score matching was performed based on preoperative factors including gender,age,weight,BMI,morbid obesity,ASA classification,smoking history and preoperative complications.Compared with group B,the dosage of sufentanil,total volume of fluid infusion,volume of blood loss were increased,time from the end of surgery to withdrawing muscle relaxant and extubation time were prolonged,and the proportion of rescue analgesia use and incidence of hypoxemia were increased in group A(P＜0.05).Multivariate logistic regression analysis showed that extubation time prolongation[OR=1.085,95％CI(1.059-1.111),P＜0.05],rescue analgesia use in PACU[OR=6.537,95％CI(1.992-21.452),P＜0.05],and hypoxemia during anesthesia recovery[OR=8.598,95％CI(4.501-16.426),P＜0.05]were the independent factors for delayed leaving PACU.Conclusion Extubation time prolongation,rescue analgesia use in PACU and hypoxemia during anesthesia recovery are the independent risk factors for delayed leaving PACU after laparoscopic bariatric surgery in obese patients.
