Proseal Lma Thesis Statements

Abstract

The laryngeal mask airway (LMA) ProSeal is most commonly used supraglottic airway device; it is routinely inserted by blind technique. Although blind insertion technique is most widely used, there are many techniques which are available such as priming the drain tube with a guiding instrument such as a suction catheter, a gum elastic bougie, a Flexi-Slip Stylet, direct laryngoscopy, and even a fiber-optic bronchoscope (FOB). The present study was undertaken to compare and assess the placement of LMA ProSeal using blind versus direct laryngoscopy techniques using FOB.A prospective randomized comparative study of 110 patients divided into two groups of 55 each as Group I (blind insertion) and Group II (direct laryngoscopic insertion) after satisfying the inclusion criteria. The anatomical position was assessed by flexible FOB and evaluated based on fiber-optic scoring system.In the present study, demographic characteristics, vital parameters, Mallampati score, and Wilson's score were comparable in both the groups (P > 0.05). The fiber-optic score (FOS) 1 in Group II was 78.18% compared to 60% in Group I, but the difference was statistically not significant (P > 0.05). Furthermore, the mean FOS in Group II was slightly high (3.84 ± 0.87) compared to Group II (1.62 ± 0.87), but the difference was statistically not significant (P > 0.05). Further hemodynamic parameters (P > 0.05) and complications (P > 0.05) were comparable in both the groups.The LMA placement scoring was similar in both blind and direct laryngoscopic techniques. Blind insertion technique is a simpler, easier, and has stood the test of time.
