Our aim was to evaluate the potential role of standard extrinsically activated thromboelastometry (EXTEM) assay in the early detection of neonatal sepsis. We studied 91 hospitalized neonates categorized in two groups: group A included 35 neonates with confirmed sepsis, while group B included 56 neonates with suspected sepsis274 healthy neonates served as controls. Whenever sepsis was suspected, EXTEM assay was performed, Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE) and Tοllner score were calculated, and clinical findings and laboratory results were recorded. Septic neonates had significantly prolonged clotting time (CT) and clot formation time (CFT), and reduced maximum clot firmness (MCF), compared to neonates with suspected sepsis (p values 0.001, 0.001, and 0.009, respectively) or healthy neonates (p values 0.001, 0.001, and 0.021, respectively). EXTEM parameters (CT, CFT, MCF) demonstrated a more intense hypocoagulable profile in septic neonates with hemorrhagic diathesis than those without (p values 0.021, 0.007, and 0.033, respectively). In septic neonates, CFT was correlated with platelet count, SNAPPE, Tollner score, and day of full enteral feeding (p values 0.01, 0.02, 0.05, and 0.03, respectively).
