Cardiac output measurement by transpulmonary versus conventional thermodilution technique in intensive care patients after coronary artery bypass grafting.
The aim of the present study was to evaluate the correlation, accuracy, and precision of transpulmonary thermodilution cardiac output (CO) measurement. For this purpose, this technique was compared with the clinical gold standard, the CO measurement by pulmonary artery catheter in patients after coronary artery bypass grafting (CABG). ⋯ In most patients, TPCO measurement will not replace the conventional technique by pulmonary artery catheter, but in some patients it offers an attractive, reliable, and safe method to determine CO.

Perioperative cardiovascular morbidity in patients with coronary artery disease undergoing vascular surgery after percutaneous transluminal coronary angioplasty.
Patients with coronary artery disease (CAD) who undergo noncardiac surgery are at increased risk for perioperative myocardial infarction (PMI). Undergoing successful coronary artery bypass grafting (CABG) before such surgery has been shown to decrease perioperative cardiac morbidity and mortality. Percutaneous transluminal coronary angioplasty (PTCA) is an alternative treatment for these patients. Perioperative cardiac morbidity in patients with CAD who underwent PTCA before their vascular surgery was reviewed. ⋯ High-risk cardiac patients undergoing vascular surgery who have had PTCA performed up to 18 months preoperatively have a low incidence of perioperative cardiac morbidity. Prophylactic PTCA may be beneficial in patients with CAD who are at high risk for perioperative cardiac complications.

Comparative StudyAprotinin versus epsilon-aminocaproic acid for aortic surgery using deep hypothermic circulatory arrest.
To compare the relative efficacy of aprotinin and epsilon-aminocaproic acid (EACA) in decreasing blood loss and transfusion requirements after aortic surgery involving deep hypothermic circulatory arrest (DHCA). ⋯ Aprotinin and EACA appear to be equally efficacious in reducing perioperative blood loss and transfusion requirements in patients undergoing aortic surgery involving DHCA. Questions of safety remain about the use of EACA in this setting that could not be addressed by this small retrospective study. A prospective, placebo-controlled study is warranted to confirm the absolute efficacy of these agents and to better define safety issues.

Randomized Controlled Trial Comparative Study Clinical TrialThe influence of propofol and midazolam/halothane anesthesia on hepatic SvO2 and gastric mucosal pH during cardiopulmonary bypass.
Because propofol is known to reduce vascular resistance, the objective of this study was to compare the indices of hepatosplanchnic circulation and oxygenation during cardiopulmonary bypass (CPB) in patients anesthetized with either propofol or midazolam/halothane. ⋯ Propofol preserved the HSvO2 during CPB and produced a more optimal relationship between the hepatosplanchnic blood flow and oxygen consumption.
