An evaluation of proseal laryngeal mask airway as an alternative to endotracheal intubation in patients undergoing laparoscopic surgeries

Abstract

Introduction: Successful management of airway without adverse events in laparoscopic surgeries is of prime importance which is commonly seen with laryngoscopy and endotracheal intubation. ProSeal LMA having unique features can be used to secure airway without these adverse effects. Our aims in this study primarily are to compare adequacy of ventilation, risk of regurgitation and aspiration of gastric fluid, effect of hemodynamic parameters during and after insertion and throughout the study and ease and
time of insertion of device. Secondary parameters are ease of gastric tube insertion and laryngopharyngeal morbidity. Methods: 60 patients of both sexes between 18 to 60 years of age, ASA physical status 1 & 2, weight between 40 to 65 kg posted for laparoscopic surgeries. After proper consent and premedication. General anaesthesia was administered to the patients who were randomly allotted to groups PLMA and EI. Adequate size device was inserted. Primary and secondary outcomes were recorded.
Result: All statistical tests were “tests of non-inferiority” with type 1 error of 0.05 and a power of 0.8.
Conclusion: ProSeal LMA is an effective alternate to endotracheal intubation in terms of adequacy of ventilation and oxygenation without pulmonary aspiration and gastric regurgitaion. Also provides better hemodynamic stability, less laryngopharyngeal morbidity and less post-operative complication
