[Fibronectin level in amniotic fluid as an index of unavoidable labor].
During uterus contractions detaching of amino-chorionic layer from uterus wall occurs and released fibronectin penetrates into amniotic fluid. The aim of this study was to estimate in a quantity mode the presence of fibronectin in amniotic fluid and to find the dependence between the fibronectin level in amniotic fluid and the period of time from collecting the sample to the labor. We wanted also to find the dependence between fibronectin level in amniotic fluid and duration of pregnancy, preterm rupture of amniotic membranes, patients' age, parity and number of deliveries. We analysed 86 pregnant women where we estimated the fibronectin level in specimens of amniotic fluid. During carrying out the experiment we noted that fibronectin is present in amniotic fluid and can be identified in a quantity mode. We have proved dependence between fibronectin level in amniotic fluid and the period of time from collecting the sample, up to the delivery. Fibronectin level in amniotic fluid in pregnancies uncomplicated with premature delivery was on the average 350 mg/ml. Increase of fibronectin in amniotic fluid above 700 mg/ml points at detaching of amino-chorionic layer and the occurrence of unavoidable preterm labor at the time no longer than 24 hours. Fibronectin level in amniotic fluid doesn't depend of pregnancy duration, preterm rupture of amniotic membranes.
