Comparative StudyBlood concentrations of enflurane before, during, and after hypothermic cardiopulmonary bypass.
The purpose of this study was to determine blood concentrations of enflurane delivered via a membrane oxygenator during hypothermic cardiopulmonary bypass (CPB) with changes in the input enflurane concentration and temperature and to characterize the pharmacokinetics of enflurane washout during and after CPB. ⋯ It is concluded that exposure to enflurane concentrations greater than 0.8% during CPB can result in high blood concentrations.

Randomized Controlled TrialThe release of systemic inflammatory mediators is independent of cardiopulmonary bypass temperature.
The aim of this study was to investigate the effect of systemic CPB temperature on the production of the key mediators of the systemic inflammatory response to coronary artery bypass graft (CABG) surgery. ⋯ The release of systemic inflammatory mediators after cardiac surgery was independent of mild hypothermia (32 degrees C) versus normothermia (36 degrees C) during CPB.

Comparative StudyUniversal leukocyte reduction of transfused red cells does not provide benefit to patients undergoing cardiac surgery.
A policy of universal leukocyte reduction of the blood supply in Finland was implemented at the beginning of 2003. The aim of the present evaluation was to determine the potential role of leukocyte-reduced red blood cells in decreasing postoperative infections. ⋯ No beneficial effect of the universal leukocyte reduction in cardiac surgery was found for culture-positive infection rates, 90-day mortality, or length of intensive care stay.

Comparative StudyThe air-leak test is not a good predictor of postextubation adverse events in children undergoing cardiac surgery.
The air-leak test is recommended as a method of assessing the appropriate size of an uncuffed endotracheal tube (ETT) in children. The authors' primary objective was to determine whether the air-leak test would predict adverse events and reintubations after the removal of the ETT in children who have undergone cardiac surgery. ⋯ The air-leak test did not predict an increased risk for postextubation adverse events and reintubations in children undergoing elective congenital heart surgery.
