Introduction. Ultrasound plays an important role in obstetrics, highlighting the sonographic markers used in the prediction of premature birth. Cervical modification plays an important role in the initiation of labour, so cervical evaluation is a major part of the prediction of premature birth. The shortening of cervical length reflects cervical maturation and it is a valuable criterion, therefore we propose to assess the risk of premature birth by calculating the cervical index in the second trimester and the qualitative dosage of fetal fibronectin from the cervical-vaginal secretion. Methodology. The study includes 45 patients with pregnancy between 24 weeks and 34 weeks, with certain risk factors: premature birth, under 34 weeks or spontaneous abortion in the second trimester, cervical cerclage; conization; presence/absence of ultrasound changes in the uterine orifice (funneling); presence/absence of sludge. The pregnant patients were then reassessed every two weeks. Results. The study includes patients between the ages of 20 and 38 years old. The age category with the highest rate of premature births was above 35 years of age, with a percentage of 28%. For the patients with LC<25 mm, in which the fetal fibronectin test was performed from the cervical-vaginal secretions and the result was positive, 14 pregnant women gave birth prematurely, at approximately two weeks after the test, and 6 pregnant women gave birth after one week. Regarding the consistency index of the cervix, it is significantly lower, with an average value of 52.1% in patients who gave birth between 28 and 34 weeks of gestation compared to 61.5% for full-term births. Conclusions. The correlation of the cervical length with the cervix consistency index and supplemented by the qualitative dosage of fetal fibronectin from the cervical-vaginal secretions may be an important benchmark in the assessment of premature birth risk.
