Stomach ultrasound before anesthesia for children to help improve safety
Official title: Evaluation of Preoperative Gastric Ultrasonography in Pediatric Patients in Terms of Patient Safety in Non-Operating Room Anesthesia Applications
Run by TC Erciyes University · NCT07581691 · Data updated 2026-11-12
This will test whether a quick ultrasound of the stomach before anesthesia can help identify which children having procedures outside the operating room are at higher risk of aspiration.

Is this trial a fit for you?
✓Likely a good fit
Children aged 0–18 years with ASA I–II status scheduled for nonoperating-room anesthesia who can tolerate the lateral decubitus position and have followed institutional fasting guidelines.
✕Probably not a fit
Patients with ASA III or higher, gastrointestinal dysfunction, prior lower esophageal or gastric surgery, BMI over 40, reflux or other delayed gastric emptying risk factors, or emergency cases are unlikely to benefit from the results.

What this trial studies
This observational study uses preoperative gastric ultrasound to measure stomach contents and estimate gastric volume in pediatric patients scheduled to receive anesthesia outside the operating room. Measurements are performed before anesthesia, typically with the child in the lateral decubitus position, and findings are compared with fasting history and clinical risk factors. The study enrolls ASA I–II patients aged 0–18 and excludes children with gastrointestinal dysfunction, prior gastric surgery, high BMI, or other conditions that affect gastric emptying. Researchers aim to define the relationship between ultrasound-determined gastric content/volume and the risk of postoperative aspiration to inform safer perioperative management.
Why it matters
Potential benefit: If successful, this could help clinicians identify children at increased aspiration risk before anesthesia and allow changes in fasting, monitoring, or airway management to improve safety.
How similar studies have gone: Gastric ultrasound has been used successfully in adults and there is growing pediatric evidence supporting its ability to estimate gastric volume, but standards for routine preoperative use in children remain limited.

Inclusion Criteria: * Children between 0-18 years of age and ASA I-II patients will be included in the study. Exclusion Criteria: * Patients over 18 years of age, * ASA-III and above patients, * patients with gastrointestinal dysfunction, * patients who cannot assume the lateral decubitus position for gastric -ultrasound measurements, * those who have had previous lower esophageal or gastric surgery, * those who do not comply with institutional fasting guidelines, * those with concomitant systemic diseases affecting gastric emptying, * those with a high body mass index (BMI) \> 40 kg/m2, * those with gastroesophageal reflux or aspiration risk factors, and emergency cases with delayed gastric emptying despite appropriate fasting time will not be included in the study.
