Comparative StudyPatients' conscious recollections from cardiac anesthesia.
To estimate the current incidence of conscious recollections from the time of anesthesia, the contribution of anesthetic drugs to this incidence, and the patients' experience of cardiac anesthesia and surgery. ⋯ The incidence of awareness and recall is similar to the incidence reported during general surgery. Cardiac surgery does not carry increased risk of awareness. Benzodiazepines given during anesthesia are effective in decreasing the incidence of recalled awareness, and the experience of awareness is not often particularly traumatizing. Premedication with benzodiazepine is not effective in preventing recollection of anesthesia, however.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialIntraoperative insulin therapy does not reduce the need for inotropic or antiarrhythmic therapy after cardiopulmonary bypass.
To determine whether attempted glucose control through intraoperative insulin therapy reduces the need for inotropic or antiarrhythmic therapy after cardiopulmonary bypass (CPB). ⋯ Intraoperative insulin therapy did not reduce the use of inotropic or antiarrhythmic support after cardiac surgery with CPB. The lack of benefit may be due to the inability to prevent hyperglycemia during the physiologic stress of CPB or a tribute to the effectiveness of modern myocardial preservation techniques.

Comparative Study Clinical Trial Controlled Clinical TrialThe use of a bronchial blocker compared with a double-lumen tube for single-lung ventilation during minimally invasive direct coronary artery bypass surgery.
To investigate whether a bronchial blocker (BB) placed through a routinely used single-lumen tube (SLT) to achieve 1-lung ventilation is appropriate in patients undergoing a minimally invasive direct coronary artery bypass (MIDCAB) operation. ⋯ To achieve 1-lung ventilation during a MIDCAB procedure, the use of a BB combined with an SLT is an appropriate technique as an alternative to the commonly used DLT.

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.

Randomized Controlled Trial Comparative Study Clinical TrialA prospective, randomized comparison of thromboelastographic coagulation profile in patients receiving lactated Ringer's solution, 6% hetastarch in a balanced-saline vehicle, or 6% hetastarch in saline during major surgery.
To compare the effects of lactated Ringer's solution (LR), 6% hetastarch in a balanced-saline vehicle (HS-BS), and 6% hetastarch in normal saline (HS-NS) on coagulation using thromboelastography. ⋯ LR-treated patients exhibited a hypercoagulative profile that persisted into the postoperative period. HS-BS administration was associated with a lesser change in the coagulation profile compared with HS-NS, which was associated with a hypocoagulative state.
