Clinical TrialIncreased extracellular brain water after coronary artery bypass grafting is avoided by off-pump surgery.
To determine if coronary artery bypass graft (CABG) surgery without cardiopulmonary bypass (CPB) avoids the brain swelling known to occur after CPB, to quantify these brain water compartment changes, and to identify the water shifts as due to intracellular or extracellular water. ⋯ Changes consistent with increased extracellular brain water seen after CABG with CPB were not observed in patients undergoing CABG without CPB. The clinical significance of brain water changes and increased brain water content after surgery with CPB remains undefined.

Randomized Controlled Trial Comparative Study Clinical TrialElderly coronary artery bypass graft patients with left ventricular dysfunction are hemodynamically stable after two different doses of rocuronium.
To clarify the detailed hemodynamic responses to bolus administration of 2x 95% effective dose (ED95) and 3x ED95 of rocuronium in elderly patients with left ventricular dysfunction undergoing elective coronary artery bypass grafting (CABG). ⋯ The results demonstrate that bolus administration of rocuronium (2x to 3x ED95) in combination with high-dose fentanyl provides sufficient cardiovascular stability among elderly CABG patients with left ventricular dysfunction. The cardiovascular profile of the two different bolus doses was similar. Rocuronium, in both doses, appears to be a suitable agent for muscle relaxation, especially for patients who require a high degree of cardiovascular stability.

Randomized Controlled Trial Clinical TrialA randomized, blinded trial of the antioxidant pegorgotein: no reduction in neuropsychological deficits, inotropic drug support, or myocardial ischemia after coronary artery bypass surgery.
To determine whether patients receiving pegorgotein preoperatively would be less likely than patients receiving placebo to demonstrate postoperative cerebral or myocardial dysfunction and thus would be less likely to (1) demonstrate a decline in neuropsychologic testing after cardiopulmonary bypass, (2) receive inotropic drug support, or (3) demonstrate electrocardiographic signs of ischemia or infarction. ⋯ This study showed no positive influence of pegorgotein on the incidence of any of the findings and showed a trend toward an increased incidence of myocardial ischemia or infarction.

Randomized Controlled Trial Comparative Study Clinical TrialSevoflurane versus isoflurane in patients undergoing coronary artery bypass grafting: a hemodynamic and recovery study.
To determine if sevoflurane provides comparable hemodynamics and recovery characteristics to isoflurane in cardiac anesthesia. ⋯ At MAC equivalent doses, sevoflurane showed comparable hemodynamics to isoflurane. Both agents when used as the primary anesthetic showed similar recovery characteristics, with no statistical difference between them at any stage of the study.
