Optimization of monitoring of contractile uterus activity and fetus status in women with the threat of preterm birth

Research objective: to study the use of uterine activity and variables acceleration capacity (AC) deceleration (DC) in contractile fetal well-being monitoring women at risk preterm birth.Materials methods. 292 pregnant were included prospective study. All involved underwent ultrasound cervicometry 16 weeks. 124 with a “short cervix” III (main) group observed dynamics, as well AC/DC 26, 32 38 weeks gestation, during labor studied. In 112 II detected these terms pregnancy. They monitored via conventional cardiotocography labor. 56 I normal monitored.Results. Sensitivity specificity diagnosis threatened birth main was 97.30% 94.74% respectively. Diagnostic accuracy case according non-invasive electrocardiography 96.18%. comparison significantly lower: 89.29% 87.80% The diagnostic 88.41%.Patients all clinical groups 26 had low values. However, later found highest level. values patients reduced compared controls (p < 0.05). distress if used 91.67% 99.12% test 98.41%. sensitivity 77.78%, 89.22%. intranatal 86.82%.Conclusions. Uterine extracted from maternal abdominal signal can improve threatenedpreterm delivery. Patients have delayed neurological, which leads distress. obtained allow increasing diagnosis.
