研究目的: |
了解不同胎龄/特征新生儿脐血VitK1及VitK缺乏或拮抗剂诱导蛋白-II水平,分析新生儿脐血中VitK1缺乏的危险因素;观察胎龄≥34周的婴儿生后3个月内VKDB的发生特征及规范口服补充维生素K预防新生儿出血症的真实世界疗效,为相关卫生政策的制定以及临床医务人员在进行疾病防治和临床科研选题时提供参考;观察规范口服补充维生素K至12周的胎龄≥34周的婴儿生后4周、8周、12周时血中VitK1、PIVKA-II的水平,探索口服补充维生素K的合适剂量。 |

|
Objectives of Study: |
To investigate the levels of Vitamin K1 and Vitamin K deficiency or factor IIa-like protein induced by antagonists in umbilical cord blood from newborns of different gestational ages/characteristics, and to analyze risk factors for Vitamin K1 deficiency in neonatal cord blood; Observe the occurrence characteristics of VKDB within 3 months postpartum in infants with gestational age >=34 weeks and evaluate the real-world efficacy of standardized oral vitamin K supplementation for preventing neonatal hemorrhagic disease. Provide reference for relevant health policy formulation and clinical healthcare professionals in disease prevention and clinical research topic selection; Observe blood levels of Vitamin K1 and PIVKA-II at 4 weeks, 8 weeks, and 12 weeks postpartum in infants with gestational age >=34 weeks receiving standardized oral Vitamin K supplementation up to 12 weeks, to explore the appropriate dosage for oral Vitamin K supplementation. |
