To the investigators' knowledge, no study has looked at differences in postoperative pain
when comparing maintenance of anesthesia with isoflurane, desflurane, sevoflurane, and
propofol in laparoscopic cholecystectomy. The investigators' hypothesis is that total
intravenous anesthesia with propofol will lead to less postoperative pain in the first 24
hours after laparoscopic cholecystectomy when compared to maintenance of anesthesia with
isoflurane, desflurane or sevoflurane.
PURPOSE
To find out if maintenance of anesthesia with propofol leads to less postoperative pain after
laparoscopic cholecystectomy when compared to maintenance of anesthesia with isoflurane,
desflurane, or sevoflurane.
