Local anaesthesia, in particular retrobulbar block, is commonly used to perform cataract surgery. Known complications of retrobulbar block include cranial nerve palsies, seizures and cardiorespiratory arrest. We report a case of brainstem anaesthesia causing apnoea and loss of consciousness in a man who received retrobulbar block. The likely mechanism is inadvertent dural puncture of the optic nerve sheath and local anaesthetic injection into the cerebrospinal fluid space. As in this case, the literature reports a short-lived period of anaesthesia with usually no long-term sequelae. Although rare, it is a life-threatening complication if the patient is not appropriately resuscitated. This case highlights the need for trained personnel, with suitable monitoring and adequate resuscitation facilities in order to perform this technique.
局部麻醉，尤其是球后阻滞，常用于白内障手术。球后阻滞已知的并发症包括脑神经麻痹、癫痫发作和心肺骤停。我们报告一例在接受球后阻滞的男性患者中发生脑干麻醉导致呼吸暂停和意识丧失的病例。可能的机制是视神经鞘意外硬膜穿刺以及局部麻醉药注入脑脊液间隙。如该病例所示，文献报道这种麻醉期短暂，通常无长期后遗症。尽管罕见，但如果患者未得到适当复苏，这是一种危及生命的并发症。该病例凸显了进行这项技术需要训练有素的人员、适当的监测和足够的复苏设备。
