We often experience migration of an epidural catheter into an undesirable space. Migration of an epidural catheter into the subarachnoid space is a potentially lethal complication. Although almost all migrations of epidural catheters have been reported to occur at insertion of the catheter, we experienced a case of catheter migration into the subarachnoid space two days after its insertion. The symptoms caused by this migration were motor paralysis in the lower extremities and sensory disturbance of the trunk. Neurological and hemodynamic changes in a patient who is undergoing continuous epidural infusion of local anesthetics should be monitored carefully.
我们经常遇到硬膜外导管移位到不理想的位置。硬膜外导管移位到蛛网膜下腔是一种潜在的致命并发症。虽然几乎所有硬膜外导管移位都据报道发生在导管插入时，但我们遇到了一例导管在插入两天后移位到蛛网膜下腔的病例。这种移位引起的症状是下肢运动麻痹和躯干感觉障碍。接受局部麻醉药持续硬膜外输注的患者的神经和血流动力学变化应仔细监测。
