Background: Laryngoscopy and intubation are mandatory for patients undergoing general anesthesia. Direct laryngoscopy and intubation along with pneumoperitoneum with carbon dioxide (CO2) insufflation for laparoscopic surgery cause afferent sympatho-adrenal response, this causes increase in blood pressure (BP), heart rate (HR) and cardiac arrhythmias in some patients Oral Clonidine premedication has been recently shown to have a potential to prevent such harmful responses.
Aim: To evaluate the efficacy of administration of oral Clonidine premedication to attenuate hemodynamic responses due to laryngoscopy, intubation and pneumoperitoneum during laparoscopic surgery.
Methods: After taking informed consent, 200 patients were systematically randomised into two groups of 100 each. Patients were kept NPO 8 hours, after proper preanesthetic checkup before surgery. On morning of surgery Group C received Oral Clonidine150mcg premedication 90 minutes prior to induction in the preoperative room and Group P ,oral ranitidine150mg (Pacebo) premedication 90 minutes before shifting the patient immediately afterwards to the operation room.
Results: Oral Clonidine premedication in a dose of 150 mcg orally before laryngoscopy and intubation effectively attenuates hemodynamic responses during intubation and pneumoperitoneum during elective laparoscopic cholecystectomy.
Conclusion: Oral Clonidine150mcg premedication effectively attenuates hemodynamic responses during intubation and pneumoperitoneum during laparoscopic cholecystectomy.
