Pain, Nausea, and Hospital Admission after Uterine Fibroid Embolization: A Comparison of 2 Protocols

Abstract

Uterine fibroid embolization (UFE) procedures performed from 2013 to 2019 were reviewed. Seventy-two patients were treated with a standard protocol consisting of sedation, ketorolac, ondansetron, and overnight parenteral analgesics and antiemetics. Ninety-six patients were treated with a new protocol, which added transdermal scopolamine, lorazepam, and intravenous acetaminophen. Outpatient uterine fibroid embolization (OP-UFE) not requiring hospitalization was successful in 81.4% and 2.7% of patients treated with the new and old protocols, respectively (odds ratio [OR], 141.4; P < .0001). Procedural fentanyl doses were lower with the new protocol than with the old one (mean, 148 vs 186 mcg; P = .0016). In the new protocol subset, patients were 1.01 times more likely to fail OP-UFE for every microgram increase in procedural fentanyl (OR, 0.99, P = .009), and those presenting with pain were less likely to succeed with OP-UFE than those with bleeding or bulk symptoms (OR, 0.31, P = .04). In conclusion, decreasing the opioid dose while increasing the antiemetic and nonopioid analgesic medications improves the chances of same day discharge after UFE.
