Intraventricular haemorrhage and haemostasis defects

Area of Science:

• Neonatal Medicine
• Pediatric Hematology
• Perinatal Research

Background:

• Intraventricular hemorrhage (IVH) is a significant complication in preterm infants.
• The role of hemostasis in IVH development and severity requires further elucidation.

Purpose of the Study:

• To investigate the association between hemostatic parameters and the occurrence and severity of IVH in preterm infants.
• To explore potential therapeutic targets for preventing IVH progression.

Main Methods:

• Comparison of hemostatic profiles (activated partial thromboplastin time, coagulation factors, fibrinogen, platelet count) in preterm infants with and without IVH.
• Correlation analysis between IVH grade and hemostasis abnormalities at birth and 48 hours of life.

Main Results:

• Infants with IVH exhibited prolonged activated partial thromboplastin time and reduced activity of factors II, VII, and X at 48 hours.
• A significant correlation was observed between IVH severity and hemostasis abnormalities in both cord blood and 48-hour blood samples.
• Grade IV IVH was associated with more pronounced hemostatic defects, including reduced fibrinogen at birth and decreased platelets at 48 hours.

Conclusions:

• Hemostasis abnormalities are linked to the development and severity of intraventricular hemorrhage in preterm infants.
• Correction of hemostasis derangements at birth may represent a viable strategy to mitigate IVH progression in neonates.
