However, if labor does not begin soon after the PROM, an induction of labor is recommended because it reduces rates of infections, decreases the chances that the baby will require a stay in the neonatal intensive care unit (NICU), and does not increase the rate of caesarean sections. If a woman strongly does not want to be induced, watchful waiting is an acceptable option as long as there is no sign of infection, the fetus is not in distress, and she is aware and accepts the risks of PPROM. There is not enough data to show that the use of prophylactic antibiotics (to prevent infection) is beneficial for mothers or babies at or near term because of the potential side effects and development of antibiotic resistance. 34 to 37 weeks
When the fetus is 34 to 37 weeks gestation, the risk of being born prematurely must be weighed against the risk of PROM. Previously it was recommended that delivery be carried out as if the baby was term. A 2017 Cochrane review however found waiting resulted in better outcomes when pregnancy is before 37 weeks. 24 to 34 weeks
Before 34 weeks, the fetus is at a much higher risk of the complications of prematurity. Therefore, as long as the fetus is doing well, and there are no signs of infection or placental abruption, watchful waiting (expectant management) is recommended. The younger the fetus, the longer it takes for labor to start on its own, but most women will deliver within a week.
Genetics
Many genes play a role in inflammation and collagen production, therefore inherited genes may play a role in predisposing a person to PROM. Diagnosis
To confirm if a woman has experienced PROM, a clinician must prove that the fluid leaking from the vagina is amniotic fluid, and that labor has not yet started. To do this, a careful medical history is taken, a gynecological exam is conducted using a sterile speculum, and an ultrasound of the uterus is performed. History: a person with PROM typically recalls a sudden "gush" of fluid loss from the vagina, or steady loss of small amounts of fluid. Sterile speculum exam: a clinician will insert a sterile speculum into the vagina in order to see inside and perform the following evaluations. Digital cervical exams, in which gloved fingers are inserted into the vagina to measure the cervix, are avoided until the women is in active labor to reduce the risk of infection.Pooling test: Pooling is when a collection of amniotic fluid can be seen in the back of the vagina (vaginal fornix). Sometimes leakage of fluid from the cervical opening can be seen when the person coughs or performs a valsalva maneuver. Nitrazine test: A sterile cotton swab is used to collect fluid from the vagina and place it on nitrazine (phenaphthazine) paper. Amniotic fluid is mildly basic (pH 7.1–7.3) compared to normal vaginal secretions which are acidic (pH 4.5–6). Basic fluid, like amniotic fluid, will turn the nitrazine paper from orange to dark blue.
