    AimsComparison of the use of I-gel and Laringeal Mask Airway (LMA) Protector in laparoscopic cholecystectomy regarding the time and ease of insertion for supraglottic airway devices (SAD) and gastric tube (GT), airway sealing capacity, and postoperative complications.Patients And MethodsSixty-four American Society of Anaesthesiologists (ASA) I-III patients undergoing laparoscopic cholecystectomy were randomly allocated into two groups. After anesthesia induction, LMA Protector was inserted in Group LPRO (LMA Protector) (n = 33) and I-gel was inserted in Group IGEL (I-gel) (n = 31) patients. Time of SAD insertion, number of attempts, time, and ease of GT insertion were recorded. The peak inspiratory pressure (PIP) and oropharyngeal leak pressure (OLP) were measured at the time of SAD insertion, 10 min after insertion, 10 min after pneumoperitoneum, and just before the termination of pneumoperitoneum. The presence of bloodstains on SAD, sore throat, hoarseness, nausea, and pain in swallowing was assessed postoperatively. A P value of < 0.05 was accepted as statistically significant.ResultTwo patients in Group LPRO needed endotracheal intubation and were excluded from the study. The SAD insertion time was shorter in Group IGEL than in Group LPRO (13 ± 7.4 s vs. 18.8 ± 9.8 s). The number of attempts and success rate on the first attempt were similar in both groups. GT insertion time was shorter in Group IGEL than Group LPRO (11 ± 7.7 s vs. 21 ± 11 s). The insertion of GT was easier in Group IGEL. The OLP levels decreased during the pneumoperitoneum in Group LPRO while they remained constant in Group IGEL.ConclusionWe observed that I-gel offers more stable airway sealing and easier GT insertion advantages when compared with LMA Protector in laparoscopic cholecystectomy.
