Intra-aortic balloon counterpulsation: outcome in cardiac surgical patients.
To identify the major determinants of survival and nonsurvival for patients in need of intra-aortic balloon pump (IABP) support after cardiac surgery and to define the role of ventilator-associated pneumonia. ⋯ These data suggest that for patients not weaned from the IABP, the major determinants of death are low cardiac output (33.3%) and multiorgan failure (47.6%). Patients with a left ventricular ejection fraction of <30% have a poorer outcome. In patients weaned from the IABP, ventilator-associated pneumonia (66.6%) was the major cause of death.

Randomized Controlled Trial Clinical TrialComparison of nicardipine versus placebo to control hemodynamic responses during emergence and extubation.
To compare 2 different doses of intravenous nicardipine versus placebo to control heart rate and blood pressure responses to emergence and extubation. ⋯ Compared with placebo, both nicardipine doses attenuated blood pressure but not heart rate responses during emergence and extubation. Greater blood pressure control occurred with the larger nicardipine dose of 0.03 mg/kg.

Clinical Trial Controlled Clinical TrialEffects of preoperative treatment with diltiazem on diastolic ventricular function after coronary artery bypass graft surgery.
To examine whether preoperative treatment with diltiazem could ameliorate left ventricular (LV) diastolic dysfunction in patients after coronary artery bypass graft (CABG) surgery. ⋯ Diastolic function is preserved after CABG surgery and is not altered by diltiazem in patients with preserved LV systolic function. The persistence of increased peak A velocity and TVI-A into the postoperative period suggests improved atrial systolic function with diltiazem.

Randomized Controlled Trial Comparative Study Clinical TrialChest radiograph interpretation skills of anesthesiologists.
To assess the skills of anesthesiologists in the interpretation of chest radiographs. ⋯ Anesthesiologists are deficient in skills for the interpretation of chest radiographs. The skill level of university-based physicians is not greater than physicians in private practice, and skill level does not improve with level of training or experience. Most anesthesiologists rely on radiologists for interpretative results. Further training during the residency years may help improve diagnostic skills.

Pharmacokinetics of sufentanil in patients undergoing coronary artery bypass graft surgery.
To determine the pharmacokinetics of sufentanil in patients undergoing coronary artery bypass graft surgery. ⋯ The authors have determined a pharmacokinetic model for sufentanil that can be used to maintain desired target concentrations of sufentanil before cardiopulmonary bypass, with a high degree of accuracy and acceptable variability. Concomitantly administered medications (lorazepam, morphine-scopolamine, clonidine, or propofol) do not appear to have any clinically important effects on distribution-phase sufentanil pharmacokinetics.
