概括
在分娩期间的侧侧位置可能会减少第一次母亲的表皮切割和围撕裂. 然而,要密切监测产后血流,因为随着这些姿势,血流可能会增加.
科学领域:
- 产科和妇科 产科和妇科
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 劳动和交付实践 劳动和交付实践
背景情况:
- 劳动的第二阶段涉及显著的母亲的努力和潜在的周围骨创伤.
- 使用各种劳动位置,石头切割是传统的,侧面位置引起了人们对潜在益处的关注.
研究的目的:
- 调查侧面位置与石头切割位置在分娩的第二阶段对母亲和新生儿的结果的影响.
- 评估对周围骨的完整性,表皮切割率,分娩时间,血液损失和新生儿福祉的影响.
主要方法:
- 一项涉及三个中国医院的前性观察研究.
- 倾向性得分匹配 (PSM) 用于比较女性在石头切割和侧面位置之间的结果.
- 分析了孕产妇的结果 (腹膜撕裂,表皮切割,失血,分娩时间,分娩方式) 和新生儿的结果 (阿巴尔分数).
主要成果:
- 侧侧姿势与21%的表皮切除术使用率降低和较少的中度周围撕裂有关.
- 在分娩持续时间,分娩方式或严重产后出血 (>500毫升) 方面没有发现显著差异.
- 然而,横向的位置与分娩时间增加10分钟和分娩后更大的流血损失有关,无论是初产还是产后的妇女.
结论:
- 侧侧位置可能会在分娩期间为初生产妇提供围保护.
- 临床判断至关重要,特别是在分娩前妇女,分娩进展缓慢的情况下.
- 建议所有使用横向姿势的妇女,无论平衡,都应对产后血流的高度警.

Observational Studies
11.1K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Sign Test for Matched Pairs
415
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Introduction to z Scores
11.2K
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...
