Arterial pulse cardiac output agreement with thermodilution in patients in hyperdynamic conditions.
This study aimed to compare continuous cardiac output (CCO) obtained using the arterial pulse wave (APCO) measurement with a simultaneous measurement of the intermittent cardiac output (ICO) and CCO obtained with a pulmonary artery catheter (PAC) in liver transplant patients. ⋯ APCO enables the assessment of CO with clinically acceptable bias and precision. At higher CO levels, APCO underestimates PAC measurements and it is not as reliable as thermodilution in hyperdynamic liver transplant patients.

Randomized Controlled TrialA randomized trial evaluating different modalities of levosimendan administration in cardiac surgery patients with myocardial dysfunction.
To evaluate the effects of 2 different administration modalities of levosimendan (start before cardiopulmonary bypass [CPB] and at the end of CPB) compared with a standard treatment with milrinone started at the end of CPB in cardiac surgery patients with a preoperative ejection fraction <30%. ⋯ In the conditions of the present study, starting the levosimendan treatment before CPB was associated with a higher initial postoperative stroke volume and a lower incidence of postoperative atrial fibrillation, but had no effect on the extent of postoperative troponin I release.

Perioperative coagulation management and blood conservation in cardiac surgery: a Canadian Survey.
To determine which strategies are currently used for (anti)coagulation management and blood conservation during cardiac surgery in Canada. ⋯ The majority of Canadian institutions do not use point-of-care tests other than ACT. Most institutions do not have algorithms for management of bleeding following cardiac surgery and at least 30% do not monitor their transfusion practice perioperatively. Cardiac surgery patients in Canada may benefit from a standardized approach to blood conservation in the perioperative period.

Can ROTEM thromboelastometry predict postoperative bleeding after cardiac surgery?
To evaluate the predictive ability of ROTEM thromboelastometry (Pentapharm, Basel, Switzerland) to identify patients bleeding more than 200 mL/h in the early postoperative period after cardiac surgery. ⋯ ROTEM thromboelastometry has poor predictive utility to identify patients who bleed more than 200 mL/h in the early postoperative period after cardiac surgery. However, its negative predictive value was good.

Myocardial performance index is a predictor of outcome after abdominal aortic aneurysm repair.
Perioperative measurement of the myocardial performance index (MPI) with transesophageal echocardiography in patients undergoing elective abdominal aortic aneurysm repair and its association with outcome. ⋯ The MPI is an easily obtained echocardiographic measure of global ventricular performance, which can be measured perioperatively and may be useful as a prospective risk stratification index for patients undergoing elective abdominal aortic aneurysm surgery.
