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.

Comparative StudyUncalibrated arterial pulse contour analysis versus continuous thermodilution technique: effects of alterations in arterial waveform.
To compare an arterial pressure-derived cardiac output (APCO) (Vigileo software version 1.07; Edwards Lifesciences, Irvine, CA) and a thermodilution cardiac output (CCO) as methods for measuring cardiac output under different pathologic and experimental conditions that induce changes in arterial waveform morphology. ⋯ Cardiac output measurement based on uncalibrated pulse contour analysis is able to reflect cardiac output measured with the continuous thermodilution method in patients undergoing uncomplicated coronary artery surgery. However, in situations in which the arterial pressure waveform is changed, agreement between techniques may be altered and data obtained with uncalibrated pulse contour analysis may become less reliable.

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.
