Background. The safety of non-anesthesiologist-administered propofol (NAAP) sedation in emergent endoscopic retrograde cholangiopancreatography (ERCP) has not been fully clarified. Thus, the aim of this study was to assess the safety of NAAP sedation in emergent ERCP. Materials and Methods. We retrospectively analyzed 182 consecutive patients who had obstructive jaundice and who underwent ERCP under NAAP sedation. The patients were divided into Group A (with mild acute cholangitis or without acute cholangitis) and Group B (moderate or severe acute cholangitis). And technical safety and adverse events were assessed. Results. The adverse events were hypoxia (31 cases), hypotension (26 cases), and bradycardia (2 cases). There was no significant difference in the rate of each adverse event of hypoxia and bradycardia in either group. Although the rate of transient hypotension associated in Group B was higher than that in Group A, it was immediately improved with conservative treatment. Moreover, there were no patients who showed delayed awakening, or who developed other complications. Conclusions. In conclusion, NAAP sedation is feasible even in emergent ERCP. Although some transient adverse events (e.g., hypotension) were observed, no serious adverse events occurred. Thus, propofol can be used in emergent ERCP but careful monitoring is mandatory.
