What is Which of the following anesthetic is safe in hea failure and explain in detail?
Etomidate has proven useful in patients with valvular or ischemic hea disease who are undergoing noncardiac surgical procedures and in patients with poor cardiac function. The hemodynamic stability seen with etomidate is caused by its lack of effect on the sympathetic nervous system and on the function of the baroreceptor. In multiple studies, etomidate has been used for induction in patients with a compromised cardiovascular system who are undergoing coronary aery bypass surgery or valve surgery, as well as in patients requiring induction of general anesthesia for percutaneous transluminal coronary angioplasty, aoic aneurysm repair, and thoracic surgery. For cardioversion, the rapid onset, quick recovery, and maintenance of aerial blood pressure in these sometimes hemodynamically tenuous patients, combined with continued spontaneous respiration, make etomidate an acceptable choice.
