Background: The aim of this study was to compare dexmedetomidine and clonidine premedication in perioperative hemodynamic stability and postoperative analgesia in laparoscopic cholecystectomy.
Materials and Methods: An observational study was conducted in Sir Sunderlal hospital, Banaras Hindu University. The study included ASA I-II patients undergoing laparoscopic cholecystectomy surgery.
Patients undergoing general anaesthesia were included in the study. The control group received iv fentanyl, while patients in one experimental group received iv clonidine 1mcg/kg over 15 minutes, 30 minutes before and in another group received iv dexmedetomidine 1mcg/kg over 15 minutes, 30 minutes before the surgery. Heart Rate, SBP, MAP, DBP, ETCO2, PCO2 and Post-Operative Analgesia were compared for the 3 groups.
Results were given as mean ± SD. Data collected were analysed using Student’s t-test. Differences were considered statistically significant if P values were <0>
Results: A total of 90 patients were included and 30 patients each were randomly assigned to one of the 3 groups. Patients who received dexmedetomidine had better haemodynamic control and post-operative analgesia. Patients who received clonidine had better haemodynamic control than control group but not better than the group who received dexmedetomidine.
Conclusion: We conclude that Alpha 2 agonists specially dexmedetomidine produce diverse responses including analgesia, anxiolysis, sedation and sympatholysis.
