Bed rest for anterior placenta does not necessarily preserve the fetus. Whether or not the fetus can be preserved in this case is mainly related to the type of placenta praevia. Placenta praevia refers to the lower edge of the placenta reaching or covering the endocervix after 28 weeks, and can be divided into complete placenta praevia and partial placenta praevia. In case of complete placenta praevia, the lower edge of the placenta completely covers the endocervix, which is very dangerous and requires absolute bed rest and may lead to infection and premature rupture of membranes in case of bleeding. In case of partial placenta praevia, for the case where the lower edge only reaches the endocervix, complete bed rest is not required and the pregnant woman can perform appropriate activities without affecting the fetal preservation measures. Pregnant women diagnosed with placenta praevia should pay attention to rest, closely observe their condition and perform relevant auxiliary examinations. If recurrent heavy bleeding occurs, the pregnancy needs to be terminated as appropriate.
