Comparison of Clinical Performance of the I-Gel with Laryngeal Mask Airway (LMA) Classic-A Randomized Study
Journal Title: Journal of Medical Science And clinical Research - Year 2016, Vol 4, Issue 2
Abstract
Background: Maintenance of airway is an integral part of general anaesthesia. Various airway devices are used for this purpose. Hemodynamic changes are major hazards of general endotracheal anesthesia and are probably generated by direct laryngoscopy and endotracheal intubation. Aim: present study was undertaken to compare the performance of two supraglottic airway devices classic laryngeal mask airway and i-gel in anaesthetized, paralyzed adult patients posted for elective surgeries under general anaesthesia. Methodology: One hundred patients, scheduled for various elective surgical procedures under general anaesthesia belonging to ASA class I and II were included in the study and were randomly divided into two groups with 50 patients in each group. In Group I (n=50), i-gel supraglottic airway device was used and in Group L (n=50) classic laryngeal mask airway (c-LMA)was used. Both the devices were compared in relation to the ease of insertion, number of insertion attempts, time of insertion, airway leak pressure, haemodynamic changes, intra and post operative complications. Results: There was no statistically significant difference between the devices with respect to ease of insertion and number of attempts of insertion. The mean airway leak pressure with i-gel was significantly higher as compared with c-LMA (26.14±2.57 and19.76±2.04 cm H2O, respectively, p=0.0001). The mean time of insertion for i-gel was 17.26±2.9 secs which was significantly shorter compared to c-LMA with a mean insertion time of 24.9±4.8 secs (p=0.0001). There were no statistically significant differences in haemodynamic changes and the postoperative complications between the devices. Conclusion: Both i-gel and c-LMA are easy to insert and provide an effective airway during positive pressure ventilation, with i-gel providing a better airway sealing pressure as compared to c-LMA.
