目的：确定硬膜外一次性镇痛法对食管癌病人术后的镇痛效果和减少并发症的意义。方法：９３ 例病人随机分成实验组（ Ｔ 组，５１ 例） 和对照组（ Ｃ 组，４２ 例） ， Ｔ 组于手术结束缝合皮肤切口时经硬膜外导管于 Ｔ６ － ７ 水平注射吗啡１ ｍｇ 加１ ％ 普鲁卡因１０ ｍｌ， Ｃ 组用阿片类药物肌肉注射镇痛。结果： Ｔ 组病人术后疼痛明显减轻，各种并发症显著下降。结论：硬膜外一次性镇痛效果确切，操作方便，副作用少，对降低术后心肺并发症很有意义，尤其对年龄大、心肺功能差的病人较适合。
OBJECTIVE: To determine the effect of epidural analgesia once a day on postoperative analgesia and reduce complications in patients with esophageal cancer. METHODS: Ninety-three patients were randomly divided into the experimental group (T group, 51 cases) and the control group (C group, 42 cases). The T group was injected with an epidural catheter at the end of the surgery and the T6-7 level was injected with morphine 1 mg. Plus 1 % procaine 10 ml, group C was intramuscularly analgesic with opioids. Results: The postoperative pain in the T group was significantly reduced, and various complications were significantly decreased. Conclusion: The one-time analgesia with epidural analgesia is effective, easy to operate and has few side effects. It is of great significance for reducing postoperative heart and lung complications, especially for older patients with poor cardiopulmonary function.
