Effect of Positive End-expiratory Pressure on Gastic Residual Volume

Duygu Akyol90 enrolled

Overview

This study was designed as a prospective observational study.

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.

Outcomes

Primary Outcomes

Gastric residual volume

The primary purpose of this study is to measure gastric residual volume with peroperative gastric ultrasonography measurements. Gastric residual volume will be calculated according to gastric ultrasonography measurements.

Time frame: preoperatively, intraoperatively after laryngeal mask placement, before laryngeal mask removal at the end of surgery

Secondary Outcomes

Airway pressures

The secondary aim of this study was to evaluate the effect of positive end-expiratory pressures on airway pressures

Time frame: intraoperative process
