A case report of continuous lumbar epidural anaesthesia with chloroprocaine is described in which delayed onset, extensive and delayed spread, and prolonged duration were observed. Although placement of neither the needle nor the catheter was confirmed radiographically, the anaesthetic course may be consistent with extra-arachnoid subdural injection of the local anaesthetic solution. Other reported cases, with similar features and which may be explained in the same way, are also discussed.
本文描述了一例使用氯普鲁卡因进行连续腰段硬膜外麻醉的病例报告，该病例出现了起效延迟、广泛且延迟扩散以及持续时间延长的情况。尽管未通过影像学确认穿刺针或导管的位置，但麻醉过程可能与局部麻醉溶液蛛网膜下腔硬膜下注射相符。还讨论了其他具有类似特征且可能以相同方式解释的报告病例。
