Abstract :

INTRODUCTION : Owing to the hemodynamic response to tracheal intubation and pneumoperitoneum ,laparoscopic surgery is not devoid of risks, many drugs have been used to blunt the pressor response to achieve a stable hemodynamics.

AIMS AND OBJECTIVES : This prospective, randomized study was designed to compare the effects of dexmedetomidine and nalbuphine on orotracheal intubation,hemodynamic responses and postoperative respiratory depression during laparoscopic cholecystectomy . Any other adverse effect of both the drugs was also studied.

MATERIAL AND METHODS : A total of 100 patients of 18-60 years, ASA grade I/II of either sex for elective laparoscopic cholecystectomy under general anaesthesia were included. The patients were randomly divided into two groups of 50 patients each. Group I received IV dexmedetomidine 1.0 ug/kg and Group II received IV nalbuphine 0.2 mg/kg over 10 mins diluted in 20ml normal saline. Hemodynamic parameters were recorded.

RESULTS : Control of HR, MAP in Group I was better than in Group II during laryngoscopy, intubation and PNP. Respiratory depression was not seen in either group. No patients had marked hypotension (MAP < 60 mmHg) or adycardia ( HR < 45 / min) in both groups but there were significant decrease in HR and MAP between the two groups during induction and after giving test drug.

CONCLUSION : The present study demonstrates the benefits of dexmedetomidine over nalbuphine in hemodynamic stability and analgesic quality in laparoscopic cholecystectomy. Thus establishing its utility for attenuation of pressor response.
