概括
估计胎儿体重 (EFW) 是胎儿心脏评估的更可靠的参考值,而不是妊娠年龄 (GA). 这项研究发现,EFW在所有胎儿生长状态中与心脏参数更好地相关,包括妊娠年龄胎儿的小和大.
科学领域:
- 产周医学 产周医学
- 胎儿生理学 胎儿生理学
- 心血管研究的心血管研究.
背景情况:
- 胎儿心脏输出评估传统上依赖于妊娠年龄 (GA) 或估计胎儿体重 (EFW).
- 由于有限的验证研究,胎儿心脏输出的最佳参考标准仍然不确定.
- 目前的参考范围通常仅基于适合妊娠年龄 (AGA) 的胎儿.
研究的目的:
- 为了比较妊娠年龄 (GA) 与预估胎儿体重 (EFW) 的疗效,作为胎儿心脏输出评估的参考.
- 通过各种胎儿生长模式来确定胎儿心脏评估的最佳参考.
- 为了验证基于EFW的胎儿心脏参数的参考范围,包括非AGA胎儿.
主要方法:
- 从怀孕27周到30周之间的单独胎儿收集的前性数据的回顾性分析.
- 包括被归类为妊娠年龄小 (SGA),妊娠年龄大 (LGA) 和妊娠年龄适当 (AGA) 的胎儿,所有这些都没有结构异常.
- 使用通用添加模型评估胎儿心脏输出参数,GA和EFW之间的关联.
主要成果:
- 妊娠年龄 (GA) 与任何胎儿心脏参数 (p ≥0.282) 没有显著的关联.
- 估计的胎儿体重 (EFW) 与所有心脏参数 (p < 0.001) 显示出显著的,主要是线性关联.
- EFW 的心脏参数分布在 AGA,SGA 和 LGA 组中一致,这表明 EFW 的广泛适用性.
结论:
- 估计胎儿体重 (EFW) 是与妊娠年龄 (GA) 相比,对胎儿心脏评估的优越和更一致的参考.
- 基于EFW的参考范围为评估各种胎儿生长状态的胎儿心脏输出提供了统一的标准.
- 该研究支持使用EFW进行更明确的胎儿心脏评估,包括所有生长类别的胎儿.

Electrocardiogram
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and the T...

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...

Imaging Studies for Cardiovascular System I:Echocardiography
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...
