The causes of a large percentage of human stillbirths remain unknown, even in cases where extensive testing and autopsy have been performed. A rarely used term to describe these is sudden antenatal death syndrome or SADS, a phrase coined by Cacciatore & Collins in 2000.[1]
In cases where the cause is known, some possibilities of the cause of death are:
* bacterial infection
* birth defects, especially pulmonary hypoplasia
* chromosomal aberrations
* growth retardation
* intrahepatic cholestasis of pregnancy
* maternal diabetes
* high blood pressure, including preeclampsia
* maternal consumption of recreational drugs (such as alcohol, nicotine, etc.) or pharmaceutical drugs contraindicated in pregnancy
* postdate pregnancy
* placental abruptions
* physical trauma
* radiation poisoning
* Rh disease
* umbilical cord accidents[2]作者: 我的失败与伟大 时间: 2011-11-21 11:11:43

发病率还是蛮高的:
Stillbirth is a relatively common, but often random, occurrence. The mean stillbirth rate in the United States is approximately 1 in 115 births, which is roughly 26,000 stillbirths each year, or on an average one every 20 minutes. In Australia,[5] England, Wales, and Northern Ireland, the rate is approximately 1 in every 200 births, in Scotland 1 in 167. (From The National Statistical Office and other sources.) Many stillbirths occur at fullterm to apparently healthy mothers, and a postmortem evaluation reveals a cause of death in only about 40% of autopsied cases.作者: 可爱的小八 时间: 2011-11-21 11:12:32
