What this trial studies

This study aims to evaluate how different levels of Positive End Expiratory Pressure (PEEP) affect gastric volume in children undergoing elective surgery with general anesthesia. Participants will be randomly assigned to one of three groups receiving varying PEEP levels: 0 cmH2O, 3 cmH2O, or 5 cmH2O. The gastric volume will be assessed using ultrasound before the induction of anesthesia. The study will ensure blinding for parents and sonographers to minimize bias in the results.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 1 to 12 years with ASA physical status I or II scheduled for elective surgery under general anesthesia.

Not a fit: Patients who may not benefit from this study include those with increased risk of regurgitation, known respiratory diseases, or uncorrected congenital heart disease.

Why it matters

Potential benefit: If successful, this study could improve anesthesia safety by reducing the risk of gastric insufflation during procedures in children.

How similar studies have performed: While the specific approach of using PEEP levels in this context may be novel, similar studies have explored the effects of PEEP on respiratory mechanics and gastric volume, indicating potential for success.
