Intraventricular haemorrhage in the newborn

Area of Science:

• Neonatal Medicine
• Pediatric Hematology
• Critical Care

Background:

• Premature infants and those with respiratory distress syndrome (RDS) are susceptible to coagulation abnormalities.
• Intraventricular hemorrhage (IVH) is a serious complication in this vulnerable population.
• The role of coagulation status in predicting IVH risk requires further elucidation.

Purpose of the Study:

• To investigate the association between coagulation parameters and the incidence of intraventricular hemorrhage (IVH) in premature infants and those with RDS.
• To evaluate the efficacy of plasma coagulation factors II, VII, IX and X (PPSB) in preventing IVH in high-risk neonates.

Main Methods:

• Coagulation studies were conducted on 128 neonates (premature or with RDS).
• Infants were categorized based on coagulation results (normal vs. abnormal).
• Treatment with PPSB was administered to a subset of infants with abnormal coagulation; outcomes were compared to untreated infants and those with normal coagulation.

Main Results:

• Forty-four out of 128 infants exhibited abnormal coagulation parameters.
• Infants with both RDS and abnormal coagulation demonstrated a significantly higher risk of IVH.
• PPSB treatment in 21 infants with abnormal coagulation did not decrease the rate of IVH (6 deaths), compared to 22 untreated infants (4 deaths).
• Only one infant with normal coagulation parameters died from IVH.

Conclusions:

• The combination of RDS and abnormal coagulation identifies a high-risk group for IVH.
• PPSB administration does not appear to reduce the incidence of IVH in this cohort.
• Effective early management of RDS is postulated as the primary strategy for preventing IVH.
