Introduction: Supraglottic devices are in regular practice in India for laparoscopic cholecystectomy. Repeated use of supraglottic devices lead to risk of malfunction (herniation of cuff, inadequate seal) and transmissible infection. Proseal LMA is commonly used after cleaning many times due to economical factor. We plan this study to compare the leak fraction and incidence of gastric regurgitation after C-LMA with nasogastric tube and P-LMA in patients undergoing laparoscopic cholecystectomy.
Materials and Method: Sixty adult patients of American Society of Anaesthesiologist I, II (ASA I, II) undergoing laparoscopic cholecystectomy under general anaesthesia were allocated randomly into two equal group to receive C-LMA with nasogastric tube or P-LMA. Patients who had any contraindication for using supraglottic devices were excluded. The leak fraction, airway pressure, ease to insertion, incidence of gastric regurgitation, postoperative sore throat were compared.
Results: All patients were successfully ventilated in both the groups. There were no significant difference noted in leak fraction and incidence of regurgitation in both groups.
Conclusion: P-LMA and C-LMA with nasogastric tube are equally effective ventilatory devices for laparoscopic cholecystectomy. As C-LMA with nasogastric tube facilitates drainage even postoperatively and much cheaper, it stays an economical device for laparoscopic cholecystectomy than P-LMA.
