Comparison of I-gel and ProSeal laryngeal mask airway during volume controlled ventilation

Introduction: I-gel and the ProSeal laryngeal mask airway (PLMA) are two supra-glottic airway devices with gastric channel used for airway maintenance in anesthesia. This study was designed to evaluate the efficacy of I-gel compared with PLMA for airway maintenance in patients under general anesthesia with controlled ventilation. The aim of the study: To compare the supra-glottic airway devices, I-Gel and ProSeal Laryngeal mask airway with respect to Ease of insertion, Time taken for insertion, Airway leak pressure, Hemodynamic response during intubation. Materials and methods: A total number of, 40 patients were randomized into two groups of 20 each. After induction of anesthesia using a standardized protocol for all the patients, one of the supra-glottic airway devices was inserted. Insertion parameters, ease of gastric tube insertion, airway leak pressure, hemodynamic changes, were noted. Results: There was no significant difference in the incidence of adverse effects in both the groups. One incidence of airway trauma was noted in I-gel group. No gastric insufflations and laryngo or bronchospasm in both groups. Conclusion: Based on the result of our study we conclude that I-gel had an acceptable airway leak pressure of 23 cm H2O when compared to ProSeal whose airway leak pressure is significantly higher i-e 29 cm H2O.Both the devices provided optimal oxygenation and no fall in saturation was observed in both the groups.
