即使在产前和产期内的护理有显著发展,死产一直在不断增加,仍然是妇产科的一个重要问题。当前的流行病学研究主要关注死产。我回顾了造成死胎的已知的和可怀疑的原因，此外，还描述了相关的用来评估明确的死胎原因的相关诊断测试。在本文中,我还评论分析美国的死产。全国卫生统计中心在2001年记录了26359个死产案例。如果死产的具体原因可以解释清楚的话，就可以大大减少死产的数量。

Feto-infant mortality is increasing worldwide. Stillbirth is defined as uterofetal death at 20 weeks of gestation or greater. Stillbirths contribute as a primary factor to the growing magnitude of feto-infant mortality. The reasons for stillbirth are usually not reported. In many cases, the specific cause of fetal death remains unknown. The key risk factors include smoking, increased maternal age, being overweight, fetal-maternal hemorrhage.

Even though there has been remarkable development in prenatal and intranatal care, stillbirths have been consistently increasing and remain an important problem in obstetrics and gynecology. Current research studies focus mainly on the epidemiology of stillbirths. I review the known and suspected causes of stillbirth. It also describes the recommended diagnostic tests to evaluate definite cause of stillbirth. In this paper, I also review analysis of stillbirths in the United States (US). The National Center of Health statistics recorded 26,359 stillbirths in 2001. The number of stillbirths can be greatly reduced if the specific reasons for stillbirth are understood.

Introduction:

A pregnancy ending in stillbirth can be mentally devastating to a patient and her family. The most widely accepted definition of stillbirth is death of the fetus inside the uterus at 20 weeks of gestation or greater (Cartlidge et al., 1995). Much information is available on protocols for evaluating other types of postmortem examination but little work has been done on the evaluation of the causes of stillbirths (Mirlene et al., 2004). No universally followed protocol is available to guide the evaluation of stillbirths.

In part because a wide variety of causes can be involved in stillbirths and it can be difficult to designate a specific cause of death. A stillbirth might result from various diseases, infections, trauma or genetic defects in the mother or fetus (Gardosi et al., 2005). In many cases, a specific reason is not known. Even though stillbirths are a serious problem, few resources have been focused on them and most obstetricians lack a sound method of evaluating of stillbirths (Petersson, 2002). In this document, I will review the accepted causes of still birth and the suggested diagnostic tests for evaluating the reason behind stillborn infants. In the year 2001 in the US, the National Center of Health Statistics recorded 26,359 stillbirths (Ananth et al., 2005).

When compared to 27,568 infant deaths were reported in the same year. More than half of the stillbirths are before 28 weeks of gestation and almost 20% are close to the term. If a history of stillbirth exists then there is a 5-fold increase for subsequent stillbirth to occur. Prominent racial discrimination occurs in the rates of stillbirths. Stillbirths are almost three times more prevalent in African Amer本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
