Nausea and vomiting management

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.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.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.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.
