Spontaneous abortion

Spontaneous abortion refers to the termination of pregnancy before 28 weeks, and the fetal weight is less than 1000g.

Some countries limit the abortion period to 25 weeks or even 20 weeks, because in developed countries, the gestational age exceeds 20 weeks, and newborns weighing 600-700g also survive due to adequate treatment. opportunity. However, according to the actual situation in China, the abortion period is still limited to 28 weeks ago. Clinically, abortion that occurs at 12 weeks of pregnancy is called early abortion; the latter that occurs at 12 weeks is called late abortion. Spontaneous abortion is a common gynecological disease.
