概括
带血 (UCB) 的血红蛋白和血红素水平与非常早产婴儿的静脉新生儿血液 (NB) 密切匹配. UCB测试可以作为出生时NB测试的可靠替代方案.
科学领域:
- 新生儿医学 新生儿医学
- 儿科血液学 儿科血液学
- 临床病理学 临床病理学
背景情况:
- 准确的实验室检测在出生时对于新生儿护理至关重要,特别是对于非常早产的婴儿.
- 带血液 (UCB) 和新生儿血液 (NB) 经常被收集用于分析.
- 了解UCB和NB结果之间的一致性对于解释新生儿健康状况至关重要.
研究的目的:
- 评估从带血液 (UCB) 和新生儿血液 (NB) 样本中获得的实验室检测结果之间的一致性.
- 确定UCB是否可以作为非常早产新生儿NB测试的替代品.
- 为了确定UCB和各种NB样品类型之间的血红蛋白和血红素值测量的系统差异.
主要方法:
- 从2012年到2023年对非常早产新生儿 (<32周妊娠年龄) 的回顾性分析.
- 包括新生儿在出生后2小时内从UCB和NB样本中抽取完整血液样本的新生儿.
- 在UCB (静脉) 和NB (静脉,动脉,毛细血管) 样本之间的血红蛋白 (Hb) 和血红素 (Hct) 度中位数的比较.
主要成果:
- 总共有432名新生儿的UCB和NB值被分析.
- 在UCB中,中位数Hb (14.7 g/dL) 与静脉NB (14.8 g/dL) 相似,但与动脉NB (13.9 g/dL) 和毛细血管NB (18.7 g/dL) 不同.
- 在UCB中,中位数Hct (0.45L/L) 显示了类似的趋势,静脉NB (0.48L/L) 是可比的,而动脉NB (0.42L/L) 和毛细血管NB (0.57L/L) 显著不同. 在将UCB Hb转换为静脉NB Hb时,确定了1.08的校正因数.
结论:
- 带血 (UCB) 的血红蛋白和血红素度与非常早产婴儿的静脉新生儿血液 (NB) 测量结果相似.
- 对于这些参数,UCB测试是新生儿出生时血液测试的有效替代品.
- 在UCB和动脉/毛细血管NB样本之间观察到显著差异,突出显示了样本类型在解释中的重要性.

Bone Marrow Sampling and Transplants
327
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Fetal Circulation
953
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
