Simulation Scenario- Myocardial Ischemia in a Patient With a Cardiac Transplant After Subarachnoid Block

Publication ID Published Volume
9029 November 21, 2011 7


This resource is a simulation scenario originating from a case experienced in the operating room. In this scenario, an 80-year-old male, who had a cardiac transplant 13 years prior, undergoes a spinal anesthetic for a wide local excision of Merkel cell carcinoma in his right thigh and thereafter develops refractory hypotension and subsequent myocardial ischemia. Sympathectomy and hypotension are well-known complications of a subarachnoid block. Identification and treatment of these common occurrences are considered basic principles in the use of neuraxial blocks. In a patient with a transplanted heart, the physiology involved can be further complicated as patients are preload dependent. This scenario exposes participants to the extreme complications of a subarachnoid block (hypotension and myocardial ischemia) in a patient with a cardiac transplant, as well as to the complicated responses to different treatments.

Educational Objectives

By the end of this resource, learners will be able to:

  1. Identify sympathectomy as the cause of hypotension immediately following subarachnoid block.
  2. Discuss the diagnosis and treatment of myocardial ischemia.
  3. Describe the appropriate selection of medications in a cardiac transplant patient experiencing severe refractory intraoperative hypotension.
  4. Demonstrate effective communication with operating room staff during a crisis and delegate tasks effectively.
  5. List the differential diagnosis of intraoperative hypotension.
  6. Describe the physiology of a patient with a transplanted heart and the effect of a subarachnoid block.
  7. Describe the preoperative evaluation of a patient with a transplanted heart.
