Randomized Controlled Trial Comparative Study Clinical TrialDouble-blind comparison of intravenous butorphanol (Stadol) and fentanyl (Sublimaze) for analgesia during labor.
Our purpose was to compare the analgesic properties, effect on labor, and maternal-fetal side effects of intravenous butorphanol and fentanyl. ⋯ Both drugs were equally safe and without effect on active labor. Butorphanol provided better initial analgesia than fentanyl with fewer patient requests for more medication or epidural analgesia.
