High-Flow Nasal Oxygen During Endoscopic Retrograde Cholangiopancreatography In Geriatric Patients

간략 요약

This prospective, single-centre, randomized controlled trial evaluates whether high-flow nasal oxygen (HFNO) reduces hypoxaemia compared with conventional low-flow oxygen therapy (COT) during endoscopic retrograde cholangiopancreatography (ERCP) performed under sedation in geriatric and adult patients. One hundred ASA I-III patients undergoing ERCP were stratified by age (\<65 and ≥65 years) and randomized to receive HFNO or COT. The primary outcome is the incidence of hypoxaemia (SpO₂ ≤90%). Secondary outcomes include hypotension, haemodynamic changes, sedative consumption, and recovery time.
