Abstract

Background: Dexmedetomidine is selective alpha 2 agonist with sedative sympatholytic, analgesic properties and is used as an anaesthetic adjuvant. We have evaluated the effect of Dexmedetomidine on various Hemodynamic responses to incidences such as laryngoscopy, endotracheal intubation, exubation and pneumoperitoneum in patients who were undergoing surgeries like Laparoscopic cholecystectomy. We have used loading dose of 0. 5mcg/kg of inj. Dexmedetomidine given over 10 minutes followed by infusion of a dose of 0. 3mcg/kg/hour for the control of hemodynamic response to laparoscopy. Methods: Patient of either sex aged between 18-50 yrs, belongs to ASA I and II (AMERICAN SOCIETY OF ANAESTHESIOLOGY) posted for Laparoscopic cholecystectomy were included. Institutional ethical committee clearance was obtained prior to study. After enrolment and valid written consent was taken. 60 patients were enrolled written valid informed consent was taken. Patients were divided into two groups 30 each with computerized randomization. Base line parameters were noted. Observer and patient was blinded for the content of syringe. Group A received injection Dexmedetomidine and group B received bolus and infusion of normal saline at same rate. Routine general anaesthesia was instituted. Parameters were noted after induction, after intubation, after co2 insufflation, after 20 min, after 40 min, after co2 deflation, after extubation, after 1 and 2 hrs post-extubation. Results: Group A showed significantly less rise in HR and MAP than Group B. Requirement of intraoperative propofol was more in Group B. There was no significant difference for time taken to awakening in both groups. Conclusion: We found Injection Dexmedetomidine in given doses gave good hemodynamic control with minimal undesired effects during laparoscopy.
