Perioperative stroke associated with postoperative epidural analgesia.

ABSTRACT

A patient with an epidural catheter for postoperative analgesia developed a stroke in association with a hypotensive episode resulting from a bolus of local anesthetic. After undergoing resection for femoral chondrosarcoma under epidural anesthesia, the patient received a continuous infusion of epidural morphine for postoperative analgesia. Lidocaine 1% (10 mL in divided doses) was administered through the catheter for breakthrough pain. The patient experienced a hypotensive episode and was noted to have a motor and cortical sensory deficit of the left arm and leg 8 hours after the hypotensive episode. Clinical presentation and subsequent workup were consistent with a watershed infarction. The patient recovered full neurologic function before discharge. Postoperative hypotension from epidural analgesia may be associated with stroke; however, a cause-and-effect relationship usually cannot be established with certainty.
