Brief summary (from the registry)
Gastric POCUS has been validated and shown to be an accurate diagnostic tool in both healthy individuals and medically complex patient populations. Regional anaesthesiologists and pain management physicians frequently provide sedation or anaesthetic care for medically complex patients who fall outside the limited applicability of existing fasting guidelines, including patients with chronic pain, poor acute-on-chronic pain control, and those receiving acute or chronic opioid therapy. These patients are at risk of delayed gastric emptying and may therefore benefit from additional pre-procedural assessment using gastric ultrasound prior to elective interventions

Eligibility criteria
Show eligibility criteria (verbatim from the registry)
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
