Guillain Barre and Anesthesia— Intraoperative Disaster?

This is the case of a 76 y/o AA man with a past medical history of Hypertension and Guillain Barre Syndrome (GBS), who presented for a median sternotomy and excision of a thymic mass after workup for multiple episodes of syncope revealed the thymic mass. Intraoperatively, the patient had 2 episodes of cardiac arrest with asystole. He was adequately resuscitated and extubated. He was later determined by Neurology to have severe autonomic dysfunction and not a candidate for any elective surgery.
