Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study, it was planned to evaluate the effect of positive end-expiratory pressure on gastric residual volume in patients who will undergo outpatient pediatric surgery with laryngeal mask application on the specified dates. Patients aged 1-11 years, ASA I-II and undergoing outpatient lower abdominal and genitourinary surgery were included in the study. Since the use of positive end-expiratory pressure varies in our clinic depending on the anesthesiologist preference, the effect of this application on gastric volume will also be evaluated primarily by recording images with gastric ultrasonography at certain perioperative time periods. Secondarily, the effect of this positive end-expiratory pressure on mechanical ventilator parameters and airway pressures will be evaluated.
