Abstract
Background: Supraglottic airway devices are preferred because of their ease of insertion and minimal hemodynamic alterations, and they are used for short surgical procedures under general anesthesia. The commonly used devices are second-generation devices such as LMA Supreme and I-Gel. The current study aimed to compare the hemodynamic stress response and performance of these two devices for elective surgeries under general anesthesia. Material and Methods: This study utilized a sample size of 100 cases undergoing elective surgical procedures under general anesthesia. They were allotted to two groups of n=50 each, randomly, Group A (LMA Supreme) and Group B (I-Gel). Hemodynamic parameters were assessed at various time intervals. Ease of insertion and the number of attempts of insertion were analyzed. The Oxygen saturation SpO₂) and end-tidal carbon dioxide (EtCO₂) were recorded. The occurrences of complications in both groups were recorded and compared by appropriate statistical analysis. Results: The distribution of cases was comparable, as found by non-significant differences in the demographic profile of the cases. The insertion time was shorter in Group B compared to Group A (21.68 ± 4.02 seconds vs 26.7 ± 7.59 seconds), and the p-values were found to be significant. The rate of success in first attempt insertion was higher in I-Gel (96%) compared to LMA Supreme (90%), although not reaching statistical significance. The comparison of hemodynamic responses was similar between the two groups. The postoperative complication rates in both groups were minimal and comparable. Conclusion: The study concluded that both LMA Supreme and I-Gel are safe supraglottic devices for short surgical procedures. The hemodynamic responses were similar in both, and the incidence of postoperative complications was similar. However, I-Gel has the advantage of shorter insertion time and ease of placement, hence it can be preferred whenever feasible.
