Introduction: This prospective, randomized, double –blind study Compare LMA-C, LMA-P & ETT with respect to pulmonary ventilation, hemodynamic & gastric distention during laparoscopic cholecystectomy. Materials and Methods: We stratified 90 patients aged b/w 18 to 65 years, ASA I & II, BMI Results: Difference b/w groups with respect to SP02, ETCO2 a or airway pressure before or during peritoneal insufflations was insignificant (p≥0.05). No significant difference b/w groups with respect to stomach size (p≥0.05). Difference b/w groups with respect to hemodynamic pameters (Blood pressure, pulse rate) was insignificant b/w C- LMA & P-LMA but with respect to ETT group was significant (p≥0.05). Conclusion: Correctly placed C-LMA, P-LMA is as effective as ETT for positive pressure ventilation without clinically important gastric distention but for hemodynamic stability C-LMA & P-LMA are superior to ETT.
