Anatomy of the intercostal nerve: its importance during thoracic surgery.
Complications from attempts to block the intercostal nerves intraneurally before closure of a thoracotomy have resulted in hypotension with or without spinal block. Placement of a chest tube has resulted in transection of the intercostal nerve. The first of these complications can be avoided by not attempting intraneural block of the nerves intrathoracically. Avoidance of the latter requires careful dissection of the intercostal spaces and identification of the intercostal nerve, as opposed to stab insertion of a chest tube.
