[Insertion of an epidural catheter from the surgical wound for postoperative analgesia--a case report].

A 62-year-old male was scheduled for discectomy for lumbar disc herniation. He had bronchial asthma, and his asthma was induced by nonsteroidal anti-inflammatory drugs. We decided to use continuous epidural block for postoperative analgesia. However, he was frightened of insertion of an epidural catheter. Therefore, we planned to insert the epidural catheter before the end of surgery under general anesthesia. It was easily placed at L 5-S 1 interspace using a Tuohy needle from the surgical wound, and the contrast medium 5 ml was injected through the epidural catheter to confirm the placement. After the surgery, continuous epidural block with local anesthetics was used for two days. He did not complain of severe pain postoperatively.
