Intraventricular Hemorrhage Prediction in Premature Neonates in the Era of Hemodynamics Monitoring: a Prospective Cohort Study
Overview
Affiliations
Conclusions: There are strong relations between both low SVCF and high ACA-RI, and IVH development in premature neonates ≤ 32 weeks and birth weight ≤ 1500 g, with more significance towards catastrophic IVH. Admission RSS and LVO are the strongest factors affecting SVCF. Maternal anemia, patent ductus arteriosus size (mm/kg), and capillary refill time were significantly associated with high ACA-RI. These findings help in more understanding of pathophysiological factors affecting central perfusion that might affect the longer term neurodeveopmental outcome.
Trial Registration: This work was registered in clinical trial.gv no NCT05050032.
What Is Known: •Whether SVCF and RI-ACA can predict IVH in preterm neonates is still debatable.
What Is New: •Low SVC flow and high ACA-RI significantly increased risk of IVH, confirming the role of hypoperfusion-reperfusion cycle in IVH development. The most striking result that combined metrics using the cut-off value of < 41 ml/kg/min for SVCF and > 0.85 for ACA-RI "in the first day of life" can correctly reject the presence of IVH in 98% of patients "during the first week of life."
