medium · MCQ · Q-EB8242
An elderly patient with severe aortic stenosis and ischemic heart disease is brought to the operating room for an emergency laparotomy. To maintain hemodynamic stability and avoid profound myocardial depression or systemic vasodilation during induction, which of the following intravenous induction agents is the most appropriate choice?
- A.Propofol
- B.Thiopental
- C.EtomidateCorrect answer
- D.Sevoflurane
Solution
Etomidate is known for its remarkable cardiovascular stability, as it produces minimal changes in heart rate, stroke volume, and systemic vascular resistance. This makes it the induction agent of choice for patients with severe cardiac disease, such as aortic stenosis or coronary artery disease, where maintenance of perfusion pressure is critical.
