目的：观察一次性硬膜外腔注射吗啡治疗前列腺摘除术后疼痛的效果。方法：选择50 例前列腺增生症（BPH）患者，随机分为两组，均于持续硬膜外麻醉下行耻骨上经膀胱前列 腺摘除术。实验组于术毕拔出硬膜外管前一次性注入吗啡，对照组于术后出现疼痛时肌肉注 射哌替啶。结果：在VAPS测痛评分、膀胱痉挛次数、膀胱停止冲洗时间、术后平均住院天 数 等方面实验组均优于对照组。结论：吗啡一次性经硬膜外腔注入具有镇痛效果好而持久 、患 者康复快等优点，可用于前列腺术后镇痛。
Objective: To observe the effect of single epidural injection of morphine on post-prostatectomy pain. Methods: Fifty patients with benign prostatic hyperplasia (BPH) were randomly divided into two groups. All underwent epidural anesthesia with suprapubic transvesical prostatectomy. In the experimental group, morphine was injected once before the epidural tube was removed from the operation group, while the control group was intramuscularly injected with pethidine after the operation. Results: The experimental group was better than the control group in terms of VAPS pain score, number of bladder spasm, bladder cessation flushing time and average postoperative hospital stay. Conclusion: One-time injection of morphine through epidural space has the advantages of good analgesic effect and long lasting, quick recovery of patients, which can be used for postoperative analgesia of prostate.
