Comparison Of Dexmedetomidine and Fentanyl In Attenuation Of Hemodynamic Response To Direct Laryngoscopy And Intubation In Patient Undergoing Laparoscopic Cholecystectomy.

This is double-blind, a single centered randomized clinical trial which is based on assessing the hemodynamic stability provided by our study drugs during laryngoscopy and intubation in a patient undergoing laparoscopic cholecystectomy. In addition to that this study will assess the perioperative complication and postoperative recovery in these patients. Laparoscopy has now become the standard technique of choice for cholecystectomy which results in pathophysiological changes characterized by an increase in arterial pressure and heart rate (HR). Many types of research have been done in an attempt to minimize adverse effects by adding adjuvants to the conventional method of general anesthesia. Our research is also based on this aim. The objective of this study to determine the hemodynamic stability during laryngoscopy and intubation, peri-operative complication and post-operative recovery. The patients will be divided into two groups randomly and will be given the desired drugs via intravenous line by on floor consultant anesthetist who will be blinded to the drug. The study subjects' hemodynamics will be observed until 10 minutes of intubation. Any perioperative complication will be noted. The subjects will also be followed postoperatively in recovery to check there sedation score and recovery (Aldrete score) will be noted after 10 minutes after the patient shifted to recovery.
