Impact of Segmental Spinal Anesthesia on Pulmonary Function and Outcomes in Laparoscopic Cholecystectomy: A Randomized Controlled Pilot Trial

This is a prospective, randomised analyser blinded study. This study aims to explore the impact of segmental spinal anaesthesia on postoperative pulmonary function and overall patient outcomes in patients undergoing Laparoscopic cholecystectomy comparing it with general anaesthesia in randomised controlled pilot trials. The study duration is 2 years. Stratified randomization methodology will be used and after allocation patients will be divided into two groups( General anaesthesia and segmental spinal anaesthesia). The primary objective of this study is to compare the peak expiratory flow rate at predefined time points [ preoperative (T0), postoperative (T1) at  6 hr, postoperative day 1(T2), 24 hr postoperative day 2(T3) 48 hr in patients receiving general anaesthesia versus segmental spinal anaesthesia for laparoscopic cholecystectomy surgery. Secondary objectives are to compare other parameters for pulmonaryoutcome analysis at predefined time points , to compare the USG parameters for pulmonary function assessment during perioperative period at predefined time points,  to compare evidence of any other perioperative complication and to compare the satisfaction scores of patients and surgeons in patients undergoing laparoscopic cholecystectomy.
