概括

胎盘病理因早产 (PTB) 类别而异. 极度早产的婴儿会出现炎症,而晚期的PTB类别会出现诸如状成熟缺陷和慢性膜炎等问题,影响新生儿的结果.

科学领域:

产科和妇科产科和妇科
病理学病理学病理学
新生儿科学新生儿科学

背景情况:

早产 (PTB) 是导致婴儿死亡和发病的主要原因.
胎盘异常与PTB有关,但妊娠年龄类别之间的差异需要进一步了解.

研究的目的:

调查和比较胎盘病理发现在不同的妊娠年龄类别的PTB.
为了确定与极度早产,非常早产,中度早产和晚期早产相关的特定的胎盘病变.

主要方法:

对538个早产胎盘进行了回顾性临床病理学分析.
胎盘根据妊娠年龄分类:EPTB (<28周),VPTB (28-31.6周),MPTB (32-33.6周) 和LPTB (34-36.6周).
宏观和显微镜检查评估了各种胎盘病变,不包括死胎和多胎妊娠.

主要成果:

晚期早产 (LPTB) 是最常见的 (46.3%).
极度早产 (EPTB) 显示出更高的母亲/胎儿炎症反应和小性胀率.
非常早产 (VPTB) 和中度早产 (MPTB) 的分娩患者患有更多的胎盘梗塞和母体血管损伤.
LPTB病例经常出现延迟状成熟,慢性胆肌炎,膜缺氧和纤维素沉积.

结论:

在EPTB中,急性炎症是突出的,这表明它在启动分娩方面发挥了作用.
由于观察到的病变,母体血管损害可能与VPTB和MPTB有关.
在LPTB中胎盘问题可能会导致长期新生儿发病率.

关键词:

慢性胆肌炎是一种慢性胆肌炎.延迟状成熟的时间.孕产妇的肌脉血管病变膜缺氧是一种缺氧.在早产胎盘中,胎盘是早产的.状水腫 (Villous edema) 是一種狀水腫.

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Fetal Circulation

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...
