Inadvertent subarachnoid injection of a local anesthetic during the conduct of epidural anesthesia may have a devastating effect on the patient. The incidence of dural puncture with an epidural catheter has been reported to range from 0.5% to 0.9%. This case report demonstrates that, despite negative aspiration of cerebral spinal fluid from the catheter, subarachnoid injection of a local anesthetic can occur.
在进行硬膜外麻醉时意外将局部麻醉药注入蛛网膜下腔可能会对患者产生毁灭性影响。据报道，硬膜外导管导致硬膜穿刺的发生率在0.5%至0.9%之间。本病例报告表明，尽管从导管中回抽未得到脑脊液，但仍可能发生局部麻醉药注入蛛网膜下腔的情况。
