Comparative StudyNafamostat mesilate, as a treatment for heparin resistance, is not associated with perioperative ischemic stroke in patients undergoing cardiac surgery with cardiopulmonary bypass.
Nafamostat mesilate, a short-acting protease inhibitor, treats heparin resistance during cardiopulmonary bypass. This study tested whether nafamostat mesilate is associated with perioperative ischemic stroke. ⋯ No evidence was found that nafamostat mesilate was associated with perioperative ischemic stroke in heparin-resistant patients undergoing cardiac surgery with cardiopulmonary bypass.

Comparative StudyA comparison of endotracheal bioimpedance cardiography and transpulmonary thermodilution in cardiac surgery patients.
The authors hypothesized that bioimpedance cardiography measured by the Endotracheal Cardiac Output Monitor (ECOM; ConMed, Utica, NY) is a convenient and reliable method for both cardiac index (CI) assessment and prediction in fluid responsiveness. ⋯ Continuous measurements of CI under dynamic conditions are consistent and easy to obtain with ECOM although not interchangeable with transpulmonary thermodilution. SVV given by ECOM is a dynamic parameter that predicts fluid responsiveness with good accuracy and discrimination.

Randomized Controlled Trial Comparative StudyEffect of atrioventricular conduction prolongation on optimization of paced atrioventricular delay for biventricular pacing after cardiac surgery.
Atrioventricular conduction prolongation (AVCP) in cardiac pacing is measurable and results primarily from delayed atrial conduction. Noninvasive methods for measuring atrial conduction are lacking. Accordingly, AVCP was used to estimate atrial conduction and investigate its role on the paced atrioventricular delay (pAVD) during biventricular pacing (BiVP) optimization. ⋯ AVCP varies widely after cardiopulmonary bypass, affecting optimum pAVD. Failure to correct for this can result in the selection of inappropriately short and potentially deleterious pAVDs, especially when nominal pAVD is used, causing BiVP to appear ineffective.
