Background: Dexmedetomidine, in addition to sympatholytic effect, diminishes intraoperative requirement of anesthetics including propofol. The present study was conducted to evaluate the effects of intravenous dexmedetomidine on intraoperative hemodynamics in laparoscopic cholecystectomy. Subjects and Methods: Five patients undergoing laparoscopic cholecystectomy received dexmedetomidine. Dexmedeto- midine was loaded (1 µg/kg) before anesthesia induction and infused (0.6 µg/kg/h) during surgery. Anesthesia was induced with propofol. Mean arterial pressure (MAP) and heart rate (HR) were recorded at baseline and at various time points from the loading of drugs to just after tracheal extubation. Results: Both HR and MAPdecreased till insufflation and then increased at extubation. Conclusion: During propofol-based anesthesia for laparoscopic cholecystectomy, dexmedetomidine provides stable intraoperative hemodynamics.
