Background: The recent advent of newer designs in supraglottic airway devices (SAD) provides a possible alternative technique to the traditional use of tracheal tubes during laparoscopic cholecystectomy. Among the supraglottic devices there are possible pros and cons for each device in laparoscopic surgeries. In our study, we compared the haemodynamic and respiratory mechanics of P-LMA and I-Gel in laparoscopic cholecystectomy. Objective: To compare the haemodynamic stability and respiratory mechanics between I-gel and proseal LMA in laparoscopic surgeries. Methods: Under optimal induction and muscle relaxation the SAD’s were inserted into the patients oral cavity and position was checked with ideal ventilation and chest rise.base line, post induction, after insertion of SAD’s, after pneuoperitonium and post operative care respiratory and haemodynamic parameters were recorded and compared. Results: Mean arterial pressure reading after insertion of SAD’S and dynamic compliance after pneumoperitonium were statistically significant with pvalue>0.05. Conclusion: It was concluded that i.Gel had better haemdynamic stability and respiratory dynamics than proseal LMA.
