Once premature rupture of membranes is confirmed and amniotic fluid flows out from the vagina, you cannot get out of bed to urinate. The reason is that if you get out of bed and stand up, the outflow of amniotic fluid will increase, and in serious cases, it may cause prolapse of the umbilical cord, leading to intrauterine distress or even fetal death. If the pregnancy week has been full-term, after 37 weeks, there is no need to insert a urinary catheter, if there is urination, you can go to the toilet to relieve urination, but in the course of labor, we must closely monitor the fetal heart and amniotic fluid changes, and if necessary, we must terminate the pregnancy in time for cesarean section.
