目的探讨蛛网膜下腔与硬膜外间隙联合注射乙醇治疗癌痛的效果。方法30例癌痛患者在蛛网膜下腔穿刺成功后,注入乙醇达一定平面,拔出腰穿针置入硬膜外导管,再于硬膜外间隙注入同一药物,保留硬膜外导管7-10日,以便必要时重复注药。直到无痛为止。结果本组患者疼痛均有不同程度的减轻,用药后25例(83.3%)患者疼痛完全消失,4例(13.3%)疼痛明显减轻;1例(占3.4%)效果较差。结论乙醇注入蛛网膜下腔与硬膜外间隙有良好的镇痛效果,两者联合用药能升高阻滞平面,可用最小的剂量达到最大的阻滞效果,呼吸循环可保持稳定,不良反应少。
Objective To investigate the effect of combined subarachnoid and epidural space injection of ethanol on cancer pain. Methods 30 cases of cancer pain patients after successful subarachnoid puncture, ethanol injection into a certain plane, pull out the lumbar puncture into the epidural catheter, and then inject the same drug in the epidural space to retain the epidural catheter 7- 10, in order to repeat injection if necessary. Until painless. Results The pain of patients in this group were relieved to varying degrees. Pain disappeared completely in 25 cases (83.3%) after treatment, and pain relief was relieved in 4 cases (13.3%). One case (3.4%) was less effective. Conclusion The injection of ethanol into the subarachnoid space and epidural space has a good analgesic effect. The combination of the two drugs can increase the block plane, with the smallest dose to achieve the maximum block effect, the respiratory cycle can be maintained stable, less adverse reactions .
