In general, if premature rupture of membranes has already occurred, it is normally necessary to rest, avoiding standing and walking. Premature rupture of membranes mainly refers to the situation where the water breaks before the onset of labor pains. This means that the membranes have ruptured and amniotic fluid may leak out at any time. Standing or walking can easily lead to continuous leakage of amniotic fluid, resulting in a reduction of the fluid or prolapse of the umbilical cord due to the leakage. If the prolapsed umbilical cord causes compressive symptoms, the fetus can quickly die within the uterine cavity. Therefore, after confirming premature rupture of membranes, it is necessary to rest in bed with the buttocks elevated and closely monitor specific fetal heart changes.
