Abstract

Modified ultrafiltration (MUF) has been shown to exert beneficial effects on the coagulation system and the capillary leak after pediatric cardiac surgery using extracorporeal circulation (ECC). The aim of this study was to investigate whether the additional use of heparin-coated circuits is a useful option for improving biocompatibility. We randomized 28 children, using heparin-coated ECC circuits in group A (n = 14) and an uncoated equivalent set in group B (n = 14). After congenital heart surgery, MUF was performed post ECC in a standardized fashion. Blood samples were analyzed preoperatively, 10 min, 30 min, 1 h, and 48 h after ECC by flow cytometric analysis (FACSort) using surface antigens CD62/CD41b (platelets) and CD45/CD14 (monocytes). No significant difference was found with respect to mean age (20.6 months vs. 21.6 months), mean body weight (9.2 kg vs. 8.4 kg), mean ultrafiltration rate (9.1 ml/kg vs. 11.4 ml/kg), chest tube drainage, blood products, ICU stay, and 30-d survival. The percentage of CD62/CD41-positive platelets in group A (vs. B) increased up to 118 % at 60 min vs. 130 % ( P < 0.05) and declined to 98 % at 48 h postop. vs. 99 % (n. s.). The percentage of CD45/CD14-positive monocytes in group A (vs. B) i...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
