Outcomes of Propofol Sedation During Emergency Endoscopy Performed for Upper Gastrointestinal Bleeding

By ?????????


Although propofol-based sedation can be used during emergency endoscopy for upper gastrointestinal bleeding (UGIB), there is a potential risk of sedation-related adverse events, especially in patients with variceal bleeding. We compared adverse events related to propofol-based sedation during emergency endoscopy between patients with non-variceal and variceal bleeding. Clinical records of patients who underwent emergency endoscopy for UGIB under sedation were reviewed. Adverse events, including shock, hypoxia, and paradoxical reaction, were compared between the non-variceal and variceal bleeding groups. Of 703 endoscopies, 539 and 164 were performed for non-variceal and variceal bleeding, respectively. Shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding (12.2 vs. 3.5 %, P < 0.001). All patients except one recovered from shock after normal saline hydration, and emergency endoscopy could be finished without interruption in most cases. The incidence of hypoxia and paradoxical reaction did not differ based on the source of bleeding (non-variceal bleeding vs. variceal bleeding: hypoxia, 3.5 vs. 1.8 %, P = 0.275; paradoxical reaction interfering with the procedure, 4.1 vs. 5.5 %, P = 0.442). Although shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding, most cases could be controlled without procedure interruption. Paradoxical reaction, rather than shock or hypoxia, was the most common cause of procedure interruption in patients with variceal bleeding, but the rate did not differ between patients with non-variceal and variceal bleeding.This work was supported by the research fund of Hanyang University (HY-2013)
