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",[24,25,26,27,28,29,30],"Gastric Ultrasound","Gastric Ultrasound in Chronic Opioid Use (≥2 Weeks)","Gastric Ultrasound in Poorly Controlled Acute-on-chronic Pain","Gastric Ultrasound in Acute Opioid Administration Within 24 Hours Prior to the Procedure","Gastric Ultrasound in Diabetes Mellitus Without Established Autonomic Neuropathy","Gastric Ultrasound in Patient With Symptoms of Gastroesophageal Reflux","Gastric Ultrasound in Patients With Reduced Functional Mobility",[32,24,33],"Gastric Ultrasound for patients with chronic pain undergoing interventional procedures under sedation","Patients with chronic pain","NOT_YET_RECRUITING","2026-04-17",{"date":37,"type":38},"2026-04-22","ACTUAL",{"date":40,"type":20},"2026-04",{"date":42,"type":20},"2027-08",{"name":44,"class":45},"Danat Al Emarat Hospital","OTHER"]
