To compare leak volume with and Without the application of positive endexpiratory Pressure with i-gel based General anaesthesia in pediatric patients- a one year randomised control trial

Abstract

Background: General anesthesia (GA) is an essential component of pediatric surgical procedures, ensuring unconsciousness, analgesia, and muscle relaxation. The use of supraglottic airway devices, such as the I-gel, has gained attention due to their ability to maintain airway patency with minimal complications. Positive end-expiratory pressure (PEEP) is widely used in adult patients to improve oxygenation and reduce airway collapse, but its benefits in pediatric patients undergoing I-gel-based GA remain unclear. This study aims to compare the effects of applying PEEP on airway leak volume and leak fraction in pediatric patients. Aims and Objectives: This study aims to compare leak volume, leak fraction, end-tidal CO₂, and peak inspiratory pressure in pediatric patients undergoing I-gel-based general anesthesia with and without 5 cm H₂O of PEEP to assess its impact on ventilation efficiency and airway leaks.
