Randomized Controlled Trial
Superior Hypogastric Nerve Block as Post-Uterine Artery Embolization Analgesia: A Randomized and Double-Blind Clinical Trial.
Purpose To evaluate the effectiveness of superior hypogastric nerve block (SHNB) in reducing narcotic use after uterine artery embolization (UAE). Materials and Methods This study was a prospective, randomized, double-blind, parallel clinical trial in patients referred to a tertiary care university teaching hospital for UAE. Forty-four participants were enrolled (mean age, 46 years; range, 32-56 years). ⋯ Of the 22 participants in the SHNB group, five (23%) needed antiemetics versus 12 of 22 participants (55%) in the sham group (P = .03). No difference in hospital admissions was observed between the two groups, and no major complications occurred from the SHNB. Conclusion Use of superior hypogastric nerve block reduces the amount of pain-related narcotics and antiemetics after uterine artery embolization. © RSNA, 2018.
