An evaluation of haemodynamic responses to tracheal intubation following intravenous dexmedetomidine and fentanyl in patients undergoing laparoscopic cholecystectomy

Dexmedetomidine in a dose of 1mcg/kg causes greater and sustained attenuation of haemodynamic response to endotracheal intubation among the patients of cholelithiasis undergoing laparoscopic cholecystectomy surgeries as compared to fentanyl. Therefore, it can be used as an effective alternative to opioids for induction of general anaesthesia in patients undergoing laparoscopic cholecystectomy surgery.
