Comparative StudyCardiac marker responses to coronary artery bypass graft surgery with cardiopulmonary bypass and aortic cross-clamping.
To study several markers of myocardial injury in relation to aortic cross-clamping and cardiopulmonary bypass (CPB) after coronary artery bypass graft (CABG) surgery. ⋯ The increase in TnT level is strongly related to aortic cross-clamping.

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.

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.

Randomized Controlled Trial Clinical TrialDoes normoxemic cardiopulmonary bypass prevent myocardial reoxygenation injury in cyanotic children?
To evaluate whether the deleterious effect of cardiopulmonary bypass (CPB) can be prevented by controlling PaO(2) in cyanotic children. ⋯ Conventional clinical methods of initiating CPB at a hyperoxemic PO(2) may increase the possibility of myocardial reoxygenation injury in cyanotic children. This deleterious effect of reoxygenation can be modified by initiating CPB at a lower level of oxygen concentration. Subsequent long-term studies are needed to determine the best method of decreasing the oxygen concentration of the CPB circuit.

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.
