Anesthesia With Propofol, Dexmedetomidine and Lidocaine Infusions for Laparoscopic Cholecystectomy
Opioids may attenuate postoperative hyperalgesia and postoperative nausea and vomiting. Our hypothesis is: opioid-free total intravenous anesthesia with propofol, dexmedetomidine and lidocaine infusions for laparoscopic cholecystectomy may achieve comparable hemodynamic stability during laparoscopy, with lower postoperative analgesic consumption and incidence of postoperative nausea and vomiting.

- Postoperative fentanyl consumption [ Time Frame: 6 hours after extubation ] [ Designated as safety issue: No ]Patients will use a Patient controlled analgesia (PCA) device for 6 hours after extubation
- Recovery time [ Time Frame: 2 hours after cessation of anesthesia infusions ] [ Designated as safety issue: Yes ]Extubation time after cessation of anesthesia infusions and discharge time from postanesthesia care unit (PACU) after extubation
- Postoperative nausea and vomiting [ Time Frame: Postoperative 24 hours ] [ Designated as safety issue: No ]

Opioid-free anesthesia (Group DL) with dexmedetomidine (0.6 mg/kg loading, 0.3 mg/kg/h infusion), lidocaine (1.5 mg/kg loading, 2 mg/kg/h infusion), and propofol infusions (3-12 mg/kg/h).
|Drug: Dexmedetomidine and lidocaine|
Opioid-based anesthesia (Group RF) with single dose fentanyl (2μg/kg), remifentanil (0.25μg/kg/min), and propofol infusions (3-12 mg/kg/h).
