OBJECTIVE: Only a few reports have addressed non-anesthesiologist-administered propofol for endoscopic ultrasonography (EUS), but none specifically in high-risk patients. Our aim was to study the application of a propofol sedation protocol for EUS in average-risk and high-risk patients. METHODS: This was a prospective observational study including 446 patients referred for EUS. We analyzed the induction time, procedure duration, recovery times, and patients' comfort and safety. Sedation was administered by a trained nurse, under the guidance of the endoscopist. We continuously monitored vital signs as well as patient cooperation and tolerance. Complications, patient, and endoscopist satisfaction were analyzed. RESULTS: No major complications occurred. The rate of minor complications was 9%, the most frequent being hypoxemia (8%). One hundred and thirty-eight high-risk patients were included [American Society of Anesthesiologists (ASA) III-IV]. Average-risk patients received higher propofol doses (202.9 ± 84.8 vs. 164.8 ± 84.3; P=0.003). No differences were found in the rate of complications or procedure-related variables. Overall patient and endoscopist satisfaction was excellent. The logistic regression model identified propofol doses (P=0.02) as a risk factor and ASA-I classification (P=0.03) as a protective factor for the appearance of complications. CONCLUSION: Non-anesthesiologist-administered propofol for upper EUS in high-risk and average-risk patients is safe and could be routinely offered to high-risk and elderly patients.
