Promising Preventive Strategies for Intraventricular Hemorrhage in Preterm Neonates: A Critical Review

Abstract

Intraventricular hemorrhage (IVH) is a common complication of prematurity and continues to represent a considerable threat due to its association with significant short- and long-term morbidity and mortality. Despite the advances in neonatal care, the prevalence of IVH, particularly in the extremely preterm neonates, remains high. Therefore, it is imperative to recognize and implement in clinical practice preventive strategies, non-pharmacological or pharmacological, to reduce IVH effectively. The aim of this narrative review is to provide an overview of novel and debatable preventive measures for IVH that are promising for clinical use and could potentially improve outcomes for very preterm neonates. IVH prevention bundles (IVHPBs) consist of strategies that aim to minimize hemodynamic and cerebral perfusion fluctuations, which are a crucial component of IVH pathogenesis. Early postnatal prophylactic indomethacin, erythropoietin, and insulin-growth factor-1 administration have shown encouraging results on IVH prevention; however, the literature is still inconclusive. Stem-cell-based interventions represent novel and promising techniques with the potential to contribute to the prevention of IVH. The prevention of IVH remains a field of investigation, and there is a requirement for conclusive evidence and recommendations. The necessity for further large-scale prospective studies is therefore evident.
