Abstract

Background and Objectives: The use of laryngeal mask airway (LMA) is an alternative route in various surgeries such as gynecologic laparoscopy. However, air leak around LMA cuff may lead to gastric distension and inadequate ventilation during positive pressure ventilation in comparison with endotracheal tube (ETT). The aim of the present study was to compare laryngeal mask airway with endotracheal tube during gynecologic laparoscopy. Materials and Methods: One hundred women were randomly divided into LMA or ETT groups for airway management. During the laparoscopy, a surgeon, blinded to the type of airway, scored stomach size on an ordinal scale of 0-10 at initial insertion of the laparoscope and immediately before the conclusion of the surgical procedure. Oxygen saturation, EtCO2, and hemodynamic parameters (HR, BP) were compared between the two groups. Results: Demographic data, peritoneal insufflations time and total anesthetic time were similar for both groups (P>0.05). Alterations in gastric distension before or after peritoneal insufflations were similar in both groups (P>0.05). There were no significant differences in SpO2, ETCO2 or hemodynamic parameters during surgery or in recovery between two groups (P>0.05). With regard to the postoperative respiratory complications, cough was more common in ETT group. Conclusion: In this study we concluded that a correctly seated LMA or ETT provided equally effective pulmonary ventilation without clinically significant gastric distension in all patients.
