Comparison of efficacy and safety of dexmedetomidine versus propofol infusion for maintaining depth of general anesthesia when muscle relaxants are not used

Background: In surgeries where direct nerve stimulation is required intraoperatively, the use of long-acting muscle relaxants should be avoided. The study aimed to assess the efficacy of dexmedetomidine versus propofol infusion in providing an adequate depth of general anesthesia where long-acting m...

description Background: In surgeries where direct nerve stimulation is required intraoperatively, the use of long-acting muscle relaxants should be avoided. The study aimed to assess the efficacy of dexmedetomidine versus propofol infusion in providing an adequate depth of general anesthesia where long-acting muscle relaxants were not used intraoperatively and to compare hemodynamics in both the groups. Patients and Methods: It was a prospective randomized controlled study done in forty patients undergoing total parotidectomy or brachial plexus surgeries. Group D received an intravenous (IV) bolus of dexmedetomidine 1 mcg/kg body weight before induction, followed by infusion at 0.7 mcg/kg/h intraoperatively. In Group B, the infusion of propofol was started at a rate of 1.5 mg/kg/h to a maximum of 100 mg/h after intubation. In both the groups, if the patient moved, bucked on the endotracheal tube, or if there were signs of inadequate depth of anesthesia, a bolus of propofol 0.5 mg/kg IV was given and repeated as required. Statistical analysis was performed using Mann–Whitney U-test and Fisher's exact test. Results: The number of times propofol bolus was required intraoperatively did not show any significant difference between groups. The mean heart rate was significantly lower in Group D before induction. At any other time points, the mean systolic blood pressure and mean arterial blood pressure were comparable in both the groups. Conclusion: Both dexmedetomidine and propofol infusions are equally effective and safe in providing an adequate depth of general anesthesia as reflected by patient immobility during surgeries where long-acting muscle relaxants were not used.
