Successful resuscitation in a case of sudden cardiac arrest in an epileptic patient posted for spinal surgery.

A 17-year-old girl was posted for spinal surgery for traumatic spinal injury. The patient was a well-controlled epileptic with history of seizure since 8 years of her age. She was induced with thiopentone sodium and muscle relaxant atracurium was administered. Minutes after that, she had an episode of ventricular tachycardia, this converted to ventricular fibrillation despite of institution of cardiopulmonary resuscitation (CPR). CPR was continued for a prolonged period of 45 minutes and after 45 minutes, QRS complexes appeared and later sinus rhythm restored. Next 24 hours, she was kept on mechanical ventilation. Within 24 hours, Glasgow Coma Scale (GCS) improved and patient was conscious and extubated. We suggest that the neuromuscular blocking drug contributed to an anaphylactic reaction which might be the cause of cardiac arrest and highlight the importance of prolonged resuscitation and successful outcome in this scenario.
