Effect of Perioperative Intravenous Lignocaine Infusion on Haemodynamic Responses and postoperative Analgesia in Laparoscopic Cholecystectomy Surgeries

During general anaesthesia, intubation of trachea and extubation of trachea are often associated with increase in haemodynamic response. Laparoscopic cholecystectomy is a minimal access surgery; postoperatively patients may experience moderate to severe pain. It is well known that lignocaine is useful in attenuating haemodynamic response to intubation and extubation. Previous studies also state that perioperative lignocaine infusion provides postoperative analgesia as well. We hypothesize that perioperative intravenous lignocaine infusion can both attenuate haemodynamic responses to intubation and extubation of trachea and also provide good postoperative analgesia in laparoscopic cholecystectomy surgeries
