Comparison of sedation efficacy of intravenous infusion of dexmedetomidine versus propofol in terms of opioid consumption in patients requiring postoperative mechanical ventilation after head and neck onco-surgeries - A randomized prospective study.

The fentanyl requirement was comparable in both the groups in the postoperative period. Dexmedetomidine was associated with an increased incidence of bradycardia and hypotension as compared to the propofol group. Propofol should be the preferred sedative for postoperative mechanical ventilation after head and neck onco-surgeries.
