Inadvertent Total Spinal Anesthesia After Intercostal Nerve Block Placement During Lung Resection

Intercostal nerve block is a recognized way of providing analgesia at thoracotomy. There is a rare association between intercostal nerve block and the complication of total spinal anesthesia. This may arise inadvertently by injection into a dural cuff extending outside the intervertebral foramen. We report our experience with a patient who sustained this life-threatening complication. The patient required postoperative ventilation until the neurologic deficits resolved. The operator must be aware that intercostal nerve block runs the rare but potentially fatal risk of total spinal block. (Ann Thorac Surg 2009; 88: 283-4) (C) 2009 by The Society of Thoracic Surgeons
