When preterm PROM is suspected, it is important to avoid performing a digital cervical examination such examinations have been shown to increase morbidity and mortality. The physician should perform a speculum examination to evaluate if any cervical dilation and effacement are present. Corticosteroids can reduce many neonatal complications, particularly intraventricular hemorrhage and respiratory distress syndrome, and antibiotics are effective for increasing the latency period. Treatment varies depending on gestational age and includes consideration of delivery when rupture of membranes occurs at or after 34 weeks’ gestation. Speculum examination to determine cervical dilation is preferred because digital examination is associated with a decreased latent period and with the potential for adverse sequelae. Appropriate evaluation and management are important for improving neonatal outcomes. It can lead to significant perinatal morbidity, including respiratory distress syndrome, neonatal sepsis, umbilical cord prolapse, placental abruption, and fetal death. It occurs in 3 percent of pregnancies and is the cause of approximately one third of preterm deliveries. This program can be ordered online by logging in to OASYS and accessing our online catalog or by contacting our Oneworld Accuracy Support team.Preterm premature rupture of membranes is the rupture of membranes during pregnancy before 37 weeks’ gestation. The increased number of samples means we can provide a greater variety of samples to participants. ![]() The test event dates remain the same as the NITZ431 format, and each sample consist of 2mL of aqueous solution. NITZ432 will be offered with three test events a year, with two samples provided per test event. Oneworld Accuracy has been offering the NITZ431 (Nitrazine) program for a number of years, and we will be adding a new format of this program starting in 2020. It must be noted that interfering substances such as blood or semen can also falsely raise the pH of vaginal fluid, and there might be subjectivity in interpretation of colour changes as well. If there is leakage of amniotic fluid, an increase of pH will be seen, and the Nitrazine strip will turn blue. A change in pH is a good indicator of PROM as normal vaginal pH is approximately between 4.5 and 6, while amniotic fluid has a higher pH range, between 7.1 and 7.3. Nitrazine is a dye that can be impregnated into paper strips and used to test pH in vaginal fluid. ![]() Nitrazine test is one of the more common laboratory techniques that can be conducted as a point-of-care (POC) test. Thus, it is of great importance to detect amniotic fluid leaks as early as possible, for better management of preterm PROM.ĭiagnosis of PROM can be through physical examination, or laboratory tests. Out of these types of ROM, preterm PROM has the greatest potential to cause serious complications such as neonatal sepsis, umbilical cord prolapses, and possibly fetal death. It may occur at term, just before onset labour, or during the preterm period, meaning before the 37 th week of gestation. Premature rupture of membranes (PROM) is a condition describing the rupture of chorioamniotic membrane during pregnancy, resulting in amniotic fluid leaks. ![]()
