Summary
Intravenous patient-controlled analgesia (PCA) is a popular technique for postoperative pain
management. Although several drugs are recognized as effective therapeutic options, optimal
selection of drugs in hysterectomy patients underwent different anesthesia treatments remains
unknown explicitly. The investigators hypothesized that butorphanol and tramadol can produce
different analgesic effects with intravenous PCA after abdominal hysterectomy.
