Hypernatremia and grade III/IV intraventricular hemorrhage among extremely low birth weight infants.

摘要

OBJECTIVE: To identify the risk factors contributing to intraventricular hemorrhage (IVH) in extremely low birth weight infants during early postnatal life, after appropriate matching for gestational age (GA) and birth body weight (BBW). STUDY DESIGN: A case-control retrospective study was designed to evaluate preterm infants with a GA 13 meq l(-1), vaginal delivery, male sex and hemoglobin fluctuations are strongly associated with the development of severe IVH. CONCLUSION: Hypernatremia and fluctuations of sodium seem to be related to early severe IVH among preterm infants; however, further studies are required to clarify the causal relationship.
