Stomach ultrasound may guide safer anesthesia for opioid users
NCT ID NCT07537582
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether using a stomach ultrasound before sedation can help anesthesiologists make safer decisions for chronic pain patients. These patients often take opioids or have other conditions that slow stomach emptying, raising the risk of food or liquid entering the lungs during sedation. The study will track how often the ultrasound changes the planned anesthesia approach.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could show that gastric ultrasound helps anesthesiologists make safer decisions for chronic pain patients, potentially reducing rare but serious complications.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures whether ultrasound changes decisions, not whether it actually prevents harm. Results may not apply to all patients.

Inclusion Criteria: Patients were eligible for inclusion if they met all of the following criteria: * Age ≥18 years * Scheduled for elective chronic pain interventional procedures under procedural sedation * Adherence to standard preoperative fasting guidelines (≥6 hours for clear fluids and ≥8 hours for solids) * Presence of at least one clinical factor associated with delayed gastric emptying or increased risk of pulmonary aspiration, including: * Chronic opioid use (≥2 weeks) * Acute opioid administration within 24 hours prior to the procedure * Poorly controlled acute-on-chronic pain * Diabetes mellitus without established autonomic neuropathy * Symptoms of gastroesophageal reflux * Reduced functional mobility * ASA physical status II-III Exclusion Criteria: Patients will be excluded if any of the following present: * Age \<18 years * Previous gastric or esophageal surgery * Known pregnancy * Known hiatal hernia * Severe neurological disorders affecting swallowing or gastric motility * Established autonomic neuropathy affecting gastric emptying (e.g. advanced diabetic gastroparesis) * Morbid obesity (body mass index ≥35 kg·m-²), due to known limitations in gastric ultrasound image acquisition and reduced validity of volume estimation models * Inability to provide informed consent
