- To calculate predictors for length of PACU stay and postoperative pain, linear multiple regression analysis (displaying ß-weight = standardized coefficient) was used; to calculate predictors for postoperative nausea and vomiting, logistic regression analysis (displaying OR = odds ratio, 95% CI = 95% confidence interval) was used.
- ASA classification American Society of Anesthesiologists’ classification, ENT ear-nose-throat, MAC monitored anaesthesia care, n.a. not applicable, RA regional anaesthesia (peripheral and central neuraxial).
- *p <0.05, **p <0.001.
