OBJECTIVE: To evaluate the effects of Han' s acupoint nerve stimulator(Han' s) on postoperative patient controlled epidural analgesia(PCEA) and recovery after surgery. METHOD: 60 patients of ASA I to II undergoing hysterectomy were randomly divided into three groups (n = 20 each) according to postoperative analgesia used: group A (Han's-and PCEA); group B (PCEA only) and group C (pethidine intramuscular). The VAS score, Ramsay score, Bruggmann comfort scale, dosage of analgesia, HAMA score, serum cortisol level and the times of hospital discharge were observed. RESULTS: The VAS score were lower in A and B groups than those in group C (p < 0.01). The dosage of analgesia in group A was (31.7 +/- 1.9) ml, as compared to (34.2 +/- 2.1) ml in group B, showing a significant difference(p < 0.01). The serum cortisol were decrease in both PCEA groups, but the level was lower in group A than in group B after operation. The ratio of anxiety in group A was lower than that in group C. The times of hospital discharge of group A was shortest in three groups. CONCLUSION: PCEA combined with transcutaneous electric nerve stimulation can enhance the analgesic efficacy, reduce analgesia dosage.
