The prevention of premature rupture of amniotic fluid is as follows: 1. insist on regular prenatal checkups, once a month for 4-6 months, once every half month for 7-9 months, once a week for 9 months or more, and do checkups whenever there are special circumstances; 2. do not engage in strenuous activities in the middle and late stages of pregnancy, do not overwork in life and work, keep a happy mood every day, and go for walks outside appropriately; 3. do not walk Long roads, running, walking carefully to avoid falling, especially when going up and down the stairs, do not carry heavy things and long bumps on the road; 4, during pregnancy to reduce sex, especially the late trimester, the last month of pregnancy to prohibit sex, so as not to stimulate the uterus, causing premature rupture of amniotic fluid. When labor is approaching, as the uterus continues to contract, the fetal membrane at the opening of the uterus cannot withstand the greater pressure and rupture, so that the amniotic fluid flows from the vagina, this situation is called water breakage. If the membranes rupture without the uterus contracting regularly and redness is seen in the vagina, that is, the membranes rupture before delivery, this is called premature rupture of membranes.
