Reversible sympathetic blocks diagnostically relieve causalgic pain. At times, repeated blocks may be therapeutic. Causalgic pain of the left hand was successfully treated in a nonsurgical candidate by a continuous infusion of local anesthetic (procaine) into the region of the stellate ganglion. This technique was performed without significant complication and gave relief from the causalgia for extended periods of time. It may provide an effective alternative to surgical sympathectomy in high-risk patients.
可逆性交感神经阻滞在诊断上可缓解灼性神经痛。有时，重复阻滞可能具有治疗作用。一名不适合手术的患者，通过向星状神经节区域持续输注局部麻醉剂（普鲁卡因），成功治疗了左手的灼性神经痛。该技术实施过程中无明显并发症，且能长时间缓解灼性神经痛。对于高危患者，它可能是手术交感神经切除术的一种有效替代方法。
