Randomized Controlled Trial Clinical TrialPlatelet pheresis is not a useful adjunct to blood-sparing strategies in cardiac surgery.
To examine whether specific platelet pheresis (minimal plasma harvested) would contribute toward reduced blood loss and allogenic blood requirements after cardiac surgery. ⋯ Platelet pheresis activates a proportion of the harvested platelets and impairs the function of the remainder; this may explain its failure to reduce postoperative blood loss and transfusion requirements.

Does the reimbursement of anesthesiologists for intraoperative transesophageal echocardiography promote increased utilization?
To determine whether access to reimbursement increases anesthesiologists' use of intraoperative transesophageal echocardiography (TEE). ⋯ The use of intraoperative TEE by anesthesiologists does not seem to be related to the availability of reimbursement from Medicare.

Splanchnic blood flow and oxygen uptake during cardiopulmonary bypass.
To measure splanchnic blood flow (SBF) with 2 indicator dilution techniques during and after cardiopulmonary bypass (CPB), to compare the results with transesophageal echocardiography Doppler-measured right hepatic vein (RHV) flow, and to study gastric tonometry data in the same patients. ⋯ SBF did not decrease during CPB. SBF could be measured with ethanol with reasonable accuracy. Transesophageal echocardiography assessment of RHV flow was not suitable to quantify SBF in the individual patient, but could be used to follow relative changes.

Neuroprotection is associated with beta-adrenergic receptor antagonists during cardiac surgery: evidence from 2,575 patients.
To determine the impact of perioperative beta-adrenergic receptor (betaAR) antagonist administration on neurologic complications. ⋯ Use of beta-adrenergic antagonists was associated with a substantial reduction in the incidence of postoperative neurologic complications. A prospective randomized trial is needed to verify this potentially important neuroprotective strategy in cardiac surgery.
