Premature rupture of membranes at term in low risk women: how long should we wait in the "latent phase"? For preterm PROM, the biggest risk is a preterm delivery, which increases risks of complications for the baby. These complications include:

As long as you’re at full term (at least 39 weeks), it may be safe to wait up to 48 hours for labor to begin. When the amniotic sac breaks, this is called rupture of the membranes in specialist circles. Ideally, this happens shortly before birth. However, in high-risk or multiple pregnancies, as well as for other reasons, it is conceivable that a rupture of the membranes occurs much earlier. Once the water has broken, a little fluid usually goes out. Many women think that this is urine fluid. If The Urine Is Cloudy Guided by ultrasound, your health care provider will insert a thin, hollow needle through your stomach wall and into the uterus. A small amount of amniotic fluid is drawn into a syringe. The needle is then removed.

This test involves testing the pH of a sample of vaginal fluid. Normal vaginal pH is between 4.5 and 6.0. Amniotic fluid has a higher pH of 7.1 to 7.3. Therefore, if the membranes have ruptured, the pH of the sample of vaginal fluid will be higher than normal. Unless there is an obvious rupture, a speculum examination will be performed to determine if there is any pooling of amniotic fluid. It is not standard NHS practice to use acidity or Ferning tests to confirm any pooling is amniotic fluid. In around 50% of cases, the wetness is urine and women are sent home. [2] However current testing methods do not always detect small ruptures and hind leaks, which is of concern for all maternity and midwifery professionals as any leak of amniotic fluid increases the risk of a serious neonatal infection (1% compared to 0.5% for women with intact membranes) and early onset of labour in that 60% of women will go into labour within 24 hours. [3] In a case-control prospective study, Marcellin et al (2011) compared the performance of2 rapid tests for the diagnosis of PROM based on the detection of IGFBP-1 and PAMG-1 in cervico-vaginal secretions. Pregnant women between 24 and 41(6/7) weeks' of gestation, consulting for profuse amniotic fluid loss (group 1) or for other reasons without any rupture of membrane (group 2) were included in the study. Successively, AmniSure test (PAMG-1) without speculum, and then Actim Prom test (IGFBP-1) during speculum examination were performed during the same visit. A total of 80subjects (40 in each group) were included between 25(1/7) to 41(1/7) weeks of gestation. AmniSure diagnostic test demonstrated a sensitivity and specificity of 95 % (82.4 to 99.4) and 94.8 % (79.3 to 98), respectively and a PPVand NPVof 95 % (84.7 to 100) and 94.8 % (87.9 to 100), respectively. Actim Prom test demonstrated a sensitivity and specificity of 97.5 % (85.7 to 100) and 97.4 % (82.4 to 99.4), respectively and aPPV and NPV of 97.5 % (88.5 to 100) and 97.4 % (92.5 to 100), respectively. The authors concluded that both tests have similar performance to diagnose PROM. The AmniSure test was performed in cases without clinical ROM (groups i,ii and iii). The AmniSure test was positive more frequently in women in labor with intact membranes than in patients not in labor at term without ROM (30.9 % (25/81 women) versus 4.8 % (6/125 women); p < 0.001). In addition, patients in labor without clinical ROM with a positive Amnisure test had a significantly shorter admission-to-delivery interval than those in labor without clinical ROM with a negative Amnisure test (p < 0.05). The authors concluded thata positive AmniSure test is present in about 1/3 nulliparous women at term presenting in labor with intact membranes; and patients with a positive AmniSure test had a shorter admission-to-delivery interval than those with a negative test.

What triggers this? Probably changes in the composition of the membranes and enzymes work in tandem with the pressure of your baby’s head. Within the scope of amniocentesis, it is possible, on the one hand, to detect diseases or hereditary changes. On the other hand, amniocentesis makes it possible to determine the concentrations of two relevant proteins in the amniotic fluid. These are the alpha-fetoprotein (AFP) and the acetylcholinesterase enzyme (AChE). If one or both of these values are elevated, this usually indicates a malformation of the abdominal wall or spinal column. How Is It Possible To Obtain Meaningful Results? Fetal membrane imaging (e.g., fusion MRI imaging, magnetic resonance elastography, optical coherence elastography, optical coherence tomography, shear wave elastography, and ultrasonography) for detecting preterm ROM The biggest risk of PROM is infection. If the uterus becomes infected (chorioamnionitis), the baby must be delivered immediately. An infection can cause serious problems for the baby.Chen FC, Dudenhausen JW.

In a comparative prospective study, Abdelazimand colleagues(2012) examined the accuracy of the PAMG-1 test(AmniSure) for the diagnose PROM. A total of 150 pregnant women after 37 weeks gestation were included in this study for induction of labor and divided into2 groups according to the presence or absence of PROM; 75 patients with PROM were included in group I and 75 patients without PROM were included in group II as controls. Patients with multiple pregnancies or fetal distress or vaginal bleeding or preterm labor or chorioamnionitis were excluded from this study. Trans-abdominal US was done to detect the gestational age and the amniotic fluid index (AFI less than or equal to 5 cm in PROM) followed by sterile speculum examination to detect amniotic fluid pooling from the cervical canal and for the collection of samples.The sensitivity and the specificity of PAMG-1 to diagnose PROM were 97.33 %and 98.67 %, respectively, compared with 84 % sensitivity and 78.67 % specificity for Ferning test and 86.67 % sensitivity and 81.33 % specificity for nitrazine test. The PPV and NPV of PAMG-1 were 98.64 %and 97.37 %, respectively, compared with 79.74 % PPV and 83.1 % NPV for Ferning test and 82.28 % PPV and 85.91 % NPV for nitrazine test. PAMG-1 was more accurate (98 %) for detection of PROM than Ferning (81.33 %) or nitrazine (84.0 %) tests.Samples of amniotic fluid were collected during caesarean section in 41 patients. A dilution series was prepared and both tests were performed twice at each dilution. Sensitivity, detection limit, response time, and reproducibility of both tests were compared. Both tests' sensitivity was 100 % at dilution 1:10 and 1:20. AmniSure sensitivity was higher at dilution 1:40 and 1:80 (p < 0.05). In 29 of 40 cases, AmniSure had a lower detection limit than Actim PROM. AmniSure response times were shorter and reproducibility was higher than Actim PROM (p < 0.05). The authors concluded that AmniSure had a lower detection limit of amniotic fluid than Actim PROM, with a shorter response time, a higher sensitivity, and a better reproducibility.
