Comparative StudyMultisite near-infrared spectroscopy predicts elevated blood lactate level in children after cardiac surgery.
To determine if a relationship exists between regional oxyhemoglobin saturation (rSO(2)) measured at various body locations by near-infrared spectroscopy (NIRS) and blood lactate level in children after cardiac surgery. ⋯ Averaged cerebral and renal rSO(2) less than 65% as measured by NIRS predicts hyperlactatemia (>3 mmol/L) in acyanotic children after congenital heart surgery. Hence, this noninvasive, continuous monitoring tool may facilitate the identification of global hypoperfusion caused by low cardiac output syndrome in this population.

Randomized Controlled Trial Comparative StudyKetamine attenuates delirium after cardiac surgery with cardiopulmonary bypass.
To determine if ketamine attenuates postoperative delirium concomitant with an anti-inflammatory effect in patients undergoing cardiac surgery using cardiopulmonary bypass. ⋯ After cardiac surgery using cardiopulmonary bypass, ketamine attenuates postoperative delirium concomitant with an anti-inflammatory effect.

Meta Analysis Comparative StudyEsmolol reduces perioperative ischemia in cardiac surgery: a meta-analysis of randomized controlled studies.
beta-Blockers were associated with a reduction of mortality and morbidity in noncardiac surgery until recently when the POISE trial showed that beta-blockers could be harmful in the perioperative period because of hypotension and bradycardia. Esmolol is an ultra-short-acting beta-blocker mostly used in emergency and high-risk patients. The authors performed a meta-analysis to evaluate the clinical effects of esmolol in cardiac surgery. ⋯ Esmolol reduces the incidence of myocardial ischemia and arrhythmias in cardiac surgery. An increase in bradycardia was noted as well.

Multicenter Study Comparative StudyVolatile anesthetics reduce mortality in cardiac surgery.
A recent meta-analysis suggested that volatile anesthetics reduce postoperative mortality after cardiac surgery. Nonetheless, whether volatile anesthetics improve the outcome of cardiac surgical patients is still a matter of debate. The authors investigated whether the use of volatile anesthetics reduces mortality in cardiac surgery. DESIGN, SETTING, AND INTERVENTIONS: A longitudinal study of 34,310 coronary artery bypass graft interventions performed in Italy estimated the risk-adjusted mortality ratio for each center. A survey was conducted among these centers to investigate whether the use of volatile anesthetics showed a correlation with mortality. ⋯ This survey among 64 Italian centers shows that risk-adjusted mortality may be reduced by the use of volatile agents in patients undergoing coronary artery bypass graft surgery.
