784 Seeking for Definitions of Poor Perfusion States (PPS) In Low Birth Weight Infants (LBWI) (Part I)

Background and Aims Echocardiography-derived low superior vena cava flow (SVCF) associates intraventricular haemorrhage, neurodisability and death. The weaknesses of the method relate to its variability. We aim to explore the relationship between two SVCF cut-off values to define PPS in LBWI and the patients’ short-term neonatal co-morbidities. Methods One hundred LBWI [27.4 (2) wks; 1014 (316) g] who reached illness score below threshold, underwent early ( Results SVCF Conclusions Low SVCF is highly prevalent in the sick LBWI during the early postnatal period. The association of low SVCF with ischemic events and adverse outcome supports this biomarker as an indicator of PPS. Disclaimer No conflict of interest.
