AbstractThis study compared the effects of propofol anesthesia and nonpropofol general anesthetics on duration of stay in the postanesthesia care unit (PACU) for prolonged drowsiness or nausea and vomiting following various surgical procedures. A group of 512 patients undergoing general anesthesia for a variety of outpatient surgical procedures over a 6-month period received general anesthesia with nitrous oxide, with or without propofol. Data collected from PACU records included type of surgical procedure and duration in the PACU of more than 2 hours owing to drowsiness or nausea and vomiting. Overall, patients who received propofol with nitrous oxide experienced less frequent drowsiness, nausea, or vomiting compared with patients who received nonpropofol anesthetic agents (drowsiness 12% vs 31%; nausea/vomiting 3% vs 25%). For patients undergoing gynecologic surgery, propofol anesthesia yielded an 8% incidence of prolonged PACU stay, compared with 41% for nonpropofol techniques. Similar results occurred for orthopedic surgery (15% vs 35%); for ear, nose, or throat procedures (30% vs 75%); and for ophthalmic surgery (18% vs 71%), but not for oral surgery (44% vs 64%). Most same-day surgery patients benefit from administration of propofol for induction and maintenance of anesthesia. Advantages include a decreased likelihood of a prolonged stay in the PACU as a result of drowsiness or nausea and vomiting.
