Comparison of bougie-guided insertion technique of proseal laryngeal mask airway with digital technique in adults undergoing general surgery

Abstract

Among the techniques used for Proseal LMA placement, we compared digital technique with bougie guided technique in terms of effective airway time, number of attempts required, hemodynamic response and complications. This prospective randomised comparative study included 60 ASA I/II patients who were divided in two groups as group A (digital technique) and group B (bougie guided insertion). The effective airway time was 35.17+/-15.54 seconds in group A vs 46.40+/-9.23 seconds in group B, p value <0.01. The first attempt successful placement was more in group B (93.3℅) vs Group A (70 ℅).The hemodynamic response was comparable in both groups, except post induction 1 min value. The effective airway time was less in group A and first attempt successful insertion rate was more in group B. The complications were less with bougie guided technique.
