Objective To observe the effects of ethanol injection into the subarachnoid space on cancer pain. Methods Sixty-eight terminally ill cancer patients with unilateral and fixed range of pain were enrolled. The patients were placed on the side and the pain side. After a successful puncture in the corresponding intervertebral space (1-3), the bed was adjusted so that the patient was in the prone position at 45°. Each space is filled with 0.5-1.0 ml anhydrous alcohol, the total amount does not exceed 1.5 ml, the injection rate is 0.2 ml/min, and the original body position is maintained for 45 minutes after injection. Results There were 4 cases of different degrees of spinal cord injury. In addition to the failure of puncture block in 7 cases, the pain was relieved. The analgesic time was generally 20 to 120 days. Conclusion This method is simple in treatment procedures, the patient’s spirit and movement are not disturbed, and patients and their families are willing to accept.
