Brief summary: The main objective of this clinical trial is to evaluate the effect of cranberry, hibiscus and vitamin C extracts supplementation on the duration of the latency of premature rupture of membranes in pregnant women between 24 and 34 weeks with PROM compared to placebo administration through a randomized double-blind clinical trial, which will be carried out from July to December 2024 in the pathological hospitalization ward of the Hospital Materno Infantil, with a sample of 84 pregnant women, divided into 2 equal groups (A and B), a control group and a placebo group, where 1 capsule per day will be administered, containing a combination of blueberry extract 100mg equivalent 36 mg, hibiscus extract 20 mg, vitamin C 500 mg with lactobacillus 200 MU or a starch capsule for 10 days. In addition, routine complementary studies will be carried out and through descriptive statistics using Redcap for data tabulation and analysis, it will be possible to prove or reject the hypothesis that proposes that the use of cranberry, vitamin C and Hibiscus supplementation does not prolong the latency of premature rupture of membranes.

Detailed description: Premature Rupture of Membranes (PROM) is the loss of the integrity of the amniotic membranes, which includes amniotic fluid leakage via the transvaginal route and manifests itself prior to the onset of labor. It has a worldwide prevalence between 2 and 4% as a complication of pregnancies, which means that it plays an important role in preterm births and maternal-fetal complications as it is a very frequent identifiable factor. Latin America is no exception, Peru has reported up to 0.31% of the total morbidities attended in the Emergency Obstetric Service. Its management can vary from expectant, pharmacological to surgical depending on factors associated with the mother and the product, for example, gestational age, clinical condition of the mother, toxic habits, among others. Epidemiological studies carried out in Mexico explain a series of factors that increase the risk of PROM. These include: maternal reproductive tract infections (bacterial vaginitis, trichomonas, gonorrhea, chlamydia and occult chorioamnioitis); behavioral factors (smoking, substance abuse, nutritional status and sexual relations); obstetric complications (multiple pregnancy, polyhydramnios, cervical incompetence, hemorrhage during pregnancy and trauma during pregnancy), as well as environmental changes (barometric pressure). On the other hand, the results of epidemiological, clinical, histological, microbiological and molecular biology studies support that focal infection and inflammation play a primary and secondary role in the pathogenesis of PROM. In 2001, the article Frequency of premature rupture of membranes in preterm labor and evaluation of short and long term management protocols in the labor and delivery room of the Honduran Institute of Social Security was published, which reported a prevalence of 20% of this condition in the study population.7% of this condition in the population studied, a situation that has improved and by 2016 the national document on Initial management and referral of obstetric and neonatal complications was adopted, which includes premature rupture of membranes and establishes a prevalence of 10% of pregnancies and 20% of cases occur in preterm gestations. PROM in preterm pregnancies is the cause of one third of preterm births and 10% of perinatal deaths; it is also associated with an increase in maternal infectious morbidity due to chorioamnionitis and puerperal infection, constituting a problem for the national health system. The present research is aimed at the interpretation and analysis of the effects observed in two groups of pregnant women diagnosed with premature rupture of membranes after the administration of cranberry extract, hibiscus and vitamin C in comparison with a group that will be administered placebo, which is consider important to know in view of the high prevalence of this pathology in our environment, since through the results new guidelines could be developed in its management that are cost effective and adapted to the availability of our institutional resources and to the condition of each patient.
