研究目的:

产前补充维生素K1可升高早产儿脐血维生素K1水平,减少维生素K1缺乏引起的出血(vitamin K deficiency bleeding,VKDB),降低早产儿颅内出血发生率并使出血程度减轻,从而减少早产儿不良预后的发生。  

Objectives of Study:

Prenatal supplementation of vitamin K1 can increase the level of vitamin K1 in cord blood of preterm infants, reduce the vitamin K deficiency bleeding (VKDB) caused by vitamin K1 deficiency, reduce the incidence and degree of intracranial hemorrhage of preterm infants, and thus reduce the occurrence of poor prognosis of preterm infants.
