Premature rupture of membranes, as the name suggests, refers to the rupture of the amniotic sac before labor commences, leading to intermittent discharge of amniotic fluid from the uterine cavity. After the membranes rupture prematurely, whether choosing to deliver or attempting to prolong the pregnancy, bed rest is required, and one should not get up to use the toilet. If one needs to use the toilet, it must be done on the bed. Standing up to use the toilet like a normal person can bring about the following risks: 1. It can cause excessive loss of amniotic fluid, leading to low levels of amniotic fluid, which can cause fetal hypoxia in the uterus. 2. Standing up to use the toilet can lead to cord prolapse or placental abruption, which can cause acute fetal hypoxia within the uterine cavity. Therefore, with premature rupture of membranes, one should not stand up to use the toilet.
