Abstract

Most of the studies using Proseal Laryngeal Mask Airway (PLMA) have used Volume Controlled Mode as ventilation mode. Although pressure-controlled (PC) ventilation potentially provides greater control over airway pressure by virtue of its decelerating inspiratory flow pattern, it remains a relatively less frequently used ventilation strategy. Thus, we aimed to compare the hemodynamic changes, ventilation changes, while using PLMA and Endotracheal tube (ETT) in PC ventilation among patients undergoing laparoscopic surgeries. Based on inclusion – exclusion criteria, 50 patients were enrolled and socio-demographic data was collected in a pre-designed proforma. Patients were then randomly allocated to receiving PLMA or ETT and haemodynamic variables, ventilatory variables, ease of insertion and postoperative complications were compared. Demographic profile of the study groups was comparable. The insertion characteristics of PLMA is like that of ETT while PLMA facilitates easy insertion of gastric tube. Mean Arterial Pressure (MAP) had a significant difference between two groups at one minute, three minutes and when measured after extubation. Patients on PLMA had significantly lesser MAP compared to the ETT group. PLMA was able to provide adequate ventilation using similar peak inspiratory pressure and tidal volume similar to that ETT in PC ventilation. Significant differences were observed in postoperative morbidities as well with PLMA having significantly less sore throat and dysphagia. Thus, we conclude that in short duration surgeries, PLMA can be used as it provides adequate ventilation using similar peak inspiratory pressure and tidal volume like that of ETT when used in PC mode of ventilation.
