概括
常规的36周超声波检查可以识别非脑部表现,但预测这些和外部脑部版本 (ECV) 的成功仍然很差. 在分娩期间进行进一步的扫描可能是有益的.
科学领域:
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 诊断性的超声波检查
- 产科 产科 产科 产科 产科
背景情况:
- 孕期非脑性胎儿表现与日产周围风险的增加有关.
- 外部头脑版本 (ECV) 是一种干预措施,用于将非头脑呈现转换为头脑呈现.
- 非脑部表现和ECV成功的预测因素需要进一步调查.
研究的目的:
- 为了确定36周妊娠时非脑部表现的发生率.
- 报告外部头脑版 (ECV) 的吸收率和成功率.
- 确定孕产妇和怀孕特征,预测非脑部表现,ECV成功和自发脑部旋转.
主要方法:
- 追溯分析从超过107,000个单独怀孕的前性收集数据.
- 超声波扫描是在妊娠35+0和36+6周之间进行的.
- 多变量逻辑回归用于识别非脑表现,ECV成功和自发旋转的预测特征.
主要成果:
- 5.8%的怀孕在36周时呈现出非头部 (后,横向或斜) 胎儿表现.
- 在25.5%的非脑病例中试图进行ECV,成功率为44.1%.
- 预测性表现的母亲和怀孕特征的非脑表现,ECV成功和自发旋转是糟糕的 (AUC 0.6080.717).
结论:
- 常规的36周超声波可以识别非脑部表现,从而有可能减少分娩时意外的异常表现.
- 基于母亲/怀孕特征的非脑表现和ECV成功的预测模型的准确性有限.
- 建议在分娩时考虑进行额外的超声波扫描,以检查胎儿表现.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

01:07Teratogenicity
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...
01:14Fetal 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...
