Comparative StudyCardiac output measured by a new arterial pressure waveform analysis method without calibration compared with thermodilution after cardiac surgery.
To investigate whether measuring cardiac output and its course after cardiac surgery by a new analysis technique of radial artery pressure waves, without need for calibration (FloTrac/Vigileo [FV]; Edwards Lifesciences, Irvine, CA), conforms to the standard bolus thermodilution method via a pulmonary artery catheter (PAC). ⋯ The FV arterial pressure waveform analysis method is a clinically applicable method for cardiac output assessment without calibration, after cardiac surgery. It performs well at low cardiac outputs but remains sensitive to changes in vascular tone.

Randomized Controlled Trial Multicenter Study Comparative StudySevoflurane provides earlier tracheal extubation and assessment of cognitive recovery than isoflurane in patients undergoing off-pump coronary artery bypass surgery.
To determine whether sevoflurane, because of its lower blood/gas partition coefficient, compared with isoflurane as the primary anesthetic agent, allows earlier tracheal extubation and assessment of cognitive function after off-pump coronary artery bypass (OPCAB) surgery. ⋯ Both sevoflurane and isoflurane may be safely used as maintenance agents in OPCAB. Sevoflurane has the advantage of allowing earlier extubation and evaluation of cognitive and neurologic function after OPCAB.

Randomized Controlled Trial Comparative StudyDesflurane versus propofol in patients undergoing mitral valve surgery.
Myocardial ischemic damage is reduced by volatile anesthetics in patients undergoing coronary artery bypass graft surgery, but it is unknown whether this benefit exists in patients undergoing valvular surgery with ischemia-reperfusion injury related to cardioplegic arrest and cardiopulmonary bypass. This study compared cardiac troponin release in patients receiving either volatile anesthetics or total intravenous anesthesia for mitral valve surgery. ⋯ Myocardial damage measured by cardiac troponin release was not reduced by volatile anesthetics in patients undergoing mitral valve surgery, whereas it was reduced in patients with concomitant coronary artery disease.
