Severe autonomic dysreflexia induced cardiac arrest under isoflurane anesthesia in a patient with lower thoracic spine injury

Abstract

We present a case of severe autonomic dysreflexia (AD) progressing to cardiac arrest and death under isoflurane anesthesia. Though AD in chronic cervical spine injury is a common entity, occurrence of such an event in the stage of flaccid paralysis in lower dorsal spinal cord injury is rare, especially under general anesthesia. Manipulation of urinary bladder catheter under light plane of isoflurane anesthesia might be the precipitating factor. Increasing concentration of isoflurane failed to abort the episode or might have aggravated it. High level of suspicion and vigilance is necessary to prevent, diagnose and treat such a condition.
