[Epidural anesthesia in obstetrics: an accidentally placed intrathecal catheter--remove it or use it?].

Epidural anesthesia is an established method in obstetrics. Despite constant practical experiences and established techniques, accidental penetrations of the dura and therefore malpositioning of the catheter in the intrathecal space are still present. This can result in post spinal headaches, a higher dispersion of the local anesthetic followed by life-threatening respiratory insufficiency and loss of overall conscious delivery. In consideration of these risks removal of the misplaced catheter and proper reinsertion in a higher position is standard. Thus significant emotional stress and re-exposure to the risks of the procedure for the parturient is accepted. We report of a 30-year-old primipara with secondary realized intrathecal placement. In due consideration of the current state of labor, we decided to leave the catheter in place and initiate a pain therapy applying bupivacain via this catheter immediately after the motor block had ceased. Within the first stage of labor sufficient pain relief was established. There was no change in tonicity. It resulted in a normal unproblematic vaginal birth. After an initial irritation due to the high dispersion the patient described a noticeable alleviation of pain during the adequate controlled labor.
