PERINATAL PROGNOSIS FOR ANOMALIES OF AMNIOTIC FLUID (literature review)
Keywords:
amniotic fluid, pregnancy, polyhydramnios, oligohydramnios.Abstract
Introduction. Amniotic fluid is a biologically active environment that surrounds the fetus, performs many functions during pregnancy and childbirth: direct contact with the inner surface of the fetal sac, has a great impact on its respiratory and motor systems. Amniotic fluid is completely renewed within 3 hours. In a full-term pregnancy, about 500-600 ml is exchanged in 1 hour, that is, 1/3 of its volume, and in 5 days - the exchange of its contents. Amniotic fluid prevents compression of the umbilical cord, due to its bacteriostatic action, infection of the uterine cavity. The amount and composition of the amniotic fluid around the fetus depends on the balance of its production and absorption. Management of pregnant women with amniotic fluid anomalies is an urgent problem of modern obstetrics.
Purpose of the study. Based on the analysis of literature data, to study perinatal outcomes with anomalies of amniotic fluid.
Material and methods. To analyze the literature, we searched for information on this problem up to 10 years in PubMed/MEDLINE, Mendeley, Medline, Researchgate, and Google Academy. For the search, the following terms were used individually or in combination: "oligohydramnios", "oligohydramnios", "polyhydramnios", "amniotic fluid", "amniotic fluid", "pregnancy". The search criteria were key stu-
dies related to oligohydramnios and polyhydramnios: meta-analyses, original studies, retrospective and cohort studies.
Results and discussion. Pregnancies with anomalies of amniotic fluid, features of childbirth and the postpartum period, the condition of the fetus and newborn are of great practical interest. Complications are often associated with the degree of pathology of the amniotic fluid. Surveillance needs to be improved to identify and prevent adverse outcomes.
Conclusions. pathology should be ruled out whenever there is a discrepancy between the change in fundal height and gestational age. Pregnant women with amniotic fluid abnormalities deserve careful antenatal and intranatal monitoring.
