Comparison of I-gel and Laryngeal mask airway (LMA) Supreme during laparoscopic Gynecological procedure

ABSTRACT

Background: The I-gel is a latex-free SAD that has a non-inflatable cuff and medical-grade thermoplastic elastomer. The design allows for a more close interaction when engaging with supraglottic tissue. The goal of the present prospective study was to compare the performance of the I-gel with that of the LMA-Supreme. Methods: The present prospective study was conducted on 100 adult patients with age between 18 to 60 years with American Society of Anesthesiologists (ASA) physical status I or II who were scheduled to undergo elective laparoscopic Gynecological procedure under general anesthesia were included in the study. Patient having gastric reflux, Obesity (BMI >30kg/m2), cervical spine disease or difficult airway were excluded from the study. The study was conducted after obtaining approval from the Institutional Review Board. A written informed consent for participation in the study was obtained from each patient. Results: The mean time for insertion in the Group SLMA was 29 sec which was significantly more as compared to 21 sec in Group I-gel (p<0.0001). 84% cases from the Group I-gel had ease of insertion which was significantly more as compared to 82% among the Group SLMA. There was no significant difference in the incidence of postoperative complications between the groups (p>0.05). Conclusion: In conclusion, both devices were similarly successful ventilatory devices for gynaecological laparoscopic procedures in terms of ease of insertion, first-time success rates, time to insertion, and oropharyngeal leak pressure
