- 新生儿科学 新生儿科学
- 儿科手术 儿科手术
背景情况:
- 专利导管动脉结合 (PDA) 是早产婴儿的常见手术.
- 了解PDA结合后的心脏适应对于优化护理至关重要.
- 患有PDA的早产婴儿在手术前表现出心脏机制的改变.
研究的目的:
- 测试假设左心室 (LV),左心室 (LA) 和右心室 (RV) 纵向菌株在早产婴儿的PDA手术后急性受损并恢复.
- 为了研究PDA结合后心脏应变的动态变化.
- 为了比较PDA和没有PDA的早产婴儿之间的心脏应变参数.
主要方法:
- 斑点跟踪回声心脏图被用于量化LV,LA和RV纵向应变.
- 在手术前和PDA绑定后4-8小时和24-48小时进行了测量.
- 为了进行比较,包括36名没有PDA的早产婴儿的对照组.
主要成果:
- 在手术前,PDA组的LV全球纵向应变 (LVGLS) 和VR自由壁应变 (RVFWSL) 比非PDA组更高.
- 结合后,LVGLS和LA储菌株 (LASr) 暂时下降,然后在24-48小时内恢复.
- RVFWSL在绑定后迅速改善,在没有显著下降的情况下恢复正常.
结论:
- LVGLS和LASr显示过渡性损伤,随后在PDA结合后恢复.
- RVFWSL在PDA结合后迅速正常化,表明心室之间的差异性适应.

Anatomy of the Heart
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
Development of the Heart
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart tube by...

Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Fetal Circulation
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...
