Randomized Controlled Trial Comparative Study
[Comparison of intravenous fentanyl analgesia and epidural analgesia for postoperative pain relief].
Epidural analgesia is available for postoperative pain relief except for the patients with bleeding tendency or under anticoagulation. Intravenous fentanyl analgesia can be applied for such patients but its effect has not been evaluated enough. We compared these two methods after abdominal surgery. ⋯ Intravenous fentanyl analgesia is safe and possibly more effective than epidural analgesia.
