Comparison of LM - Supreme and endotracheal tube in patients undergoing laparoscopic cholecystectomy Laparoskopik kolesistektomilerde LM-supreme ile endotrakeal entübasyonun karşilaştirilmasi

Objective: The aim of this study is to compare ventilation parameters and gastric distension scores with laringeal mask Supreme (LM-S) and endotracheal tube (ETT) during laparoscopic cholecystectomy. Method: 100 ASA Class I-II patients, between 18-70 years, were included to this double blind, randomised, controlled study. Patients were divided into two groups as ETT group (n=50) and LM-S group (n=50). Peroperative ventilation parameters and oropharyngeal leak pressures (OLP) were recorded before, during and after peritoneal insufflation. At the beginning and end of the surgery the gastric distention was scored. Results: Insertion time of the airway device was significantly shorter in Group LM-S (12 sec) than Group ETT (17 sec) (p=0.000). Insertion of the gastric tube was significantly easier in Group LM-S (p=0.000). The degree of gastric distention at the beginning was significantly higher in Group ETT (p=0.036). Mean OLP in the LM-S group was 29,8 cmH2O and this presure increased significantly during the insufflation period (p=0.000). Postoperative laryngopharyngeal adverse events were similar in both groups. Conclusion: Our study demonstrated that LM-S may be safe and even superior to ETT for positive pressure ventilation during laparoscopic cholecystectomy in ASA I-II patients
