Randomized Controlled Trial Clinical TrialTotal intravenous anesthesia with a propofol-ketamine combination during coronary artery surgery.
To evaluate the cardiovascular effects of a propofol-ketamine combination in patients undergoing coronary artery surgery. ⋯ The propofol-ketamine combination was associated with a similar incidence of pre-CPB hypotension and ischemia, a decreased need for inotropes after CPB, an earlier time to tracheal extubation, and a reduced incidence of myocardial infarctions compared with controls.

Thermal energy balance as a measure of adequate rewarming from hypothermic cardiopulmonary bypass.
To determine whether the amount of heat (thermal energy) used actively to rewarm patients on cardiopulmonary bypass (CPB) was a better indicator of adequate rewarming from hypothermic CPB than core temperature. ⋯ TEB is a better predictor than corresponding values of core temperature on termination of CPB in predicting the coldest postoperative temperature and time to rewarm to 37 degrees C.

Randomized Controlled Trial Comparative Study Clinical TrialHemodynamic effects of milrinone during weaning from cardiopulmonary bypass: comparison of patients with a low and high prebypass cardiac index.
To compare the hemodynamic effects of milrinone during weaning from cardiopulmonary bypass (CPB) in patients with a low pre-CPB cardiac index (CI) <2.5 L/min/m2) and in patients with a high pre-CPB CI (> or =2.5 L/min/m2). ⋯ Milrinone was effective during weaning from CPB in patients with a low pre-CPB CI. Milrinone in combination with norepinephrine was a good alternative to epinephrine for the treatment of myocardial dysfunction after CPB.

Randomized Controlled Trial Comparative Study Clinical TrialMilrinone, not epinephrine, improves left ventricular compliance after cardiopulmonary bypass.
To compare the effects of milrinone versus epinephrine administered after cardiopulmonary bypass (CPB) on left ventricular compliance. ⋯ Left ventricular compliance was decreased after CPB. The administration of milrinone, but not epinephrine, was associated with a partial return to prebypass values. The exact mechanism of action remains to be determined.

Randomized Controlled Trial Comparative Study Clinical TrialSevoflurane-fentanyl versus etomidate-fentanyl for anesthetic induction in coronary artery bypass graft surgery patients.
To compare the hemodynamic effects of sevoflurane-fentanyl with etomidate-fentanyl during anesthetic induction in patients with coronary artery disease with good left ventricular function. ⋯ Sevoflurane inhalation induction produced minimal changes in cardiac index and no airway complications in patients with coronary artery disease with good left ventricular function. Induction was faster with etomidate, however, and blood pressure remained higher.
