Which IV anesthetic does not cause cardiac depression

Etomidate:- * Cardiovascular stability after induction is a major advantage of Etomidate in contrast to Propofol or Barbiturates. * Induction doses of Etomidate typically produces: no change/small increase in hea rate; little or no decrease in blood pressure or cardiac output. Etomidate has little effect on coronary perfusion pressure while reducing myocardial O2 consumption. * It is a preferred choice of induction anesthetic in patients prone to hypotenstion or with low cardiac reserve.
