Background and Aims: Laparoscopic cholecystectomy is one of the commonly performed ambulatory surgeries. The selection of anesthetic agents for ambulatory surgeries should be done bearing in mind the need for early discharge. Opioids form an integral component of total intravenous anesthesia (TIVA) but their associated side effects may result in an increased hospital stay. Hence, we planned a study to compare the opioid (fentanyl) and non-opioid (dexmedetomidine) based technique of TIVA for laparoscopic surgery. Material and Methods: Ninety ASA I and II patients between 18-60 years of either sex posted for laparoscopic cholecystectomy were randomly allocated into two groups namely group D (Dexmedetomidine) and group F (Fentanyl). Patients received propofol infusion along with group specific drug infusion, after which an appropriate size proseal laryngeal mask airway was placed. The patients were assessed for discharge time from post-anesthesia care unit (PACU), on table recovery time, time to first rescue analgesia, hemodynamic parameters, incidence of postoperative nausea and vomiting (PONV) and any other complication. Results: Demographic profile of both the groups was comparable. Group D had longer on table recovery time (13.00 ± 2.34 min vs 6.29 ± 2.46 min; P < 0.001) and time to discharge from PACU (6.80 ± 3.96 min vs 2.36 ± 1.67 min; P < 0.001) compared to group F. Group F had better hemodynamic stability compared to group D. In group D, 77% patients required rescue analgesia in first one hour post surgery, unlike 22% in group F. No patient in group D had PONV. Conclusion: Opioid based technique (Fentanyl) of TIVA is superior over non-opioid based (dexmedetomidine) technique with faster recovery, early discharge, decreased postoperative pain scores and better hemodynamic stability. PONV is observed with opioids which can be treated successfully with antiemetics.
