The comparison of positive pressure delivered at the end of expiration administered by a supra glottic airway device with no positive pressure delivered on severity of lung collapse during/after surgery under anaesthesia

Not yet recruiting

Conditions: Medical and Surgical,

Registration Number: CTRI/2023/08/056277

Lead Sponsor: All India Institute Of Medical Sciences New Delhi

Brief Summary: To the best of our knowledge, the effect of PEEPthrough LMA on lung atelectasis under general anesthesia is an area unexplored in literature. Lung ultrasound is anexcellent tool for rapid bedside assessment of perioperative atelectasis.

Hence we planned this study to compare the effect of PEEP(8cm H2O) with No PEEP (ZEEP) applied through Proseal LMA (PLMA) onlung atelectasis, studied by lung ultrasound in patients undergoing electivelower abdominal and urological surgeries.
