Use of thromboelastography to predict thrombotic complications in pediatric and neonatal extracorporeal membranous oxygenation

Abstract

The objectives of this study were to investigate the correlation between thromboelastography (TEG) and conventional measures of anticoagulation, and to determine optimum values for citrated kaolin TEG R time (TEG RCK) and anti-Xa activity that would minimize both bleeding and thrombotic complications in pediatric and neonatal patients requiring extracorporeal membranous oxygenation (ECMO). A retrospective chart review of patients requiring veno-venous (VV) and venoarterial (VA) ECMO was performed. Combined medical and cardiac ICU within a single-center, tertiary care, freestanding, children’s hospital. Non-pregnant patients <18 years and >2 kilograms requiring VV or VA ECMO from July 2013 through July 2015. Anti-Xa (OR 5 0.62, 95% CI 0.53–0.72, p
