Comparison of intravenous analgesia with butorphanol and tramadol after hysterectomy

Objective To compare the outcomes of postoperative patient-controlled intravenous analgesia(PCIA) with butorphanol or tramadol.Methods One hundred and twelve patients underwent hysterectomy under general anesthesia were randomized to one of two groups with 56 cases each.The patients in group A were given PCIA with butorphanol 0.2 mg/kg and those in group B with tramadol 10 mg/kg.VAS and sedation scoring was performed within postoperative 48 hours.The side effects were recorded as well.Results The VAS scores and PCA numbers during analgesia were all less in group A than those in group B[(1.6±0.5) vs.(3.4±1.1) and(5 vs.11)](P0.05).The scores of sedation and patient's satisfaction were significantly higher in group A than those in group B(P0.05).The side effects occurred in 9 cases(16.1%) in group A and in 17 cases(30.4%) in group B(P0.05).Conclusion Butorphanol 0.2 mg/kg is better than tramadol 10 mg/kg for PCIA with less side effects in the patients underwent hysterectomy under general anesthesia.
