A case of a severe but brief period of shivering following a retrobulbar block (RBB) is presented. The shivering occurred within two minutes after completion of the RBB and subsided gradually within five minutes, without specific treatment. The patient remained conscious during the episode of shivering. The shivering was so abrupt and severe as to be misjudged as a seizure, but its onset appeared to be slower than a seizure. The mechanism of shivering appeared to be the central spread of local anaesthetic solution into the brain stem, along the optic nerve. Shivering may be a warning sign of brain stem anaesthesia and demands special care to anticipate life-threatening complications.
本文报告一例球后阻滞（RBB）后出现严重但短暂寒战的病例。寒战在RBB完成后两分钟内出现，并在五分钟内逐渐消退，未进行特殊治疗。患者在寒战发作期间仍保持清醒。寒战发作突然且严重，以至于被误诊为癫痫发作，但其发作似乎比癫痫发作要慢。寒战的机制似乎是局部麻醉溶液沿视神经向脑干的中枢扩散。寒战可能是脑干麻醉的一个警示信号，需要特别注意以预防危及生命的并发症。
