A child was given intramuscular benzathine penicillin and experienced manifestations of sudden, irreversible transection of the spinal cord in the lower thoracic region. The biopsy supported an intravascular injection with occlusion of the spinal vasculature as the etiological mechanism. A review of similar cases reveals a recurring pattern--intramuscular injection with standard techniques and sites into a small muscle mass without evident blood return followed by rapid progression of paralysis. The problem seems to turn upon an inability to recognize the inadvertent intraarterial injection.
一名儿童接受了苄星青霉素肌内注射，随后出现下胸段脊髓突然、不可逆横断的表现。活检支持血管内注射伴脊髓血管闭塞作为病因机制。对类似病例的回顾揭示了一种反复出现的模式——采用标准技术和部位在小肌肉群中进行肌内注射，未见明显回血，随后迅速出现瘫痪。问题似乎在于无法识别意外的动脉内注射。
