Comparative study of LMA Proseal and Tracheal Intubation for patients undergoing Laparoscopic Cholecystectomy in Indian population
Abhishek Srivastava, Somnath Longani, G.K. Sinha

We Compare the use of Proseal LMA and  Tracheal Intubation for patients undergoing Laparoscopic Cholecystectomy in this prospective and  randomized study. 62 ASA I-II patients, age >18 yrs, scheduled for elective Laparoscopic Cholecystectomy under general anaesthesia were randomly assigned into 2 groups. Group I- LMA PS- placing LMA-PS; Group II- ETT groups:- intubating tracheal tube. Depending upon the group allocation LMA-PS and ETT placed. Before and after  placing LMA-PS and intubating tracheal tube  patients were measured for  SpO2,  H.R, and NIBP. The occurrence of cough, laryngeal stridor and the need for airway intervention during emergence from anaesthesia were also recorded. Surgeon inspected the size of stomach laparoscopically. LMA-PS group provides more haemodynamic stability, less postoperative respiratory events and equally good positive pressure ventilation. Size of stomach was comparable in both groups. The only problem which we found with LMA-PS was some leak around cuff (leak fraction 16.8±6.6 & 8.9±1.6) but acceptable clinically and does not cause ventilatory problem. We therefore conclude that LMA-PS or ETT are equally effective for adequate pulmonary ventilation without gastric distension in non-obese patients in laparoscopic cholecystectomy.
Key Words: Laparoscopic Cholecystectomy, LMA-proseal, Leak fraction, Positive pressure ventilation.
