ASPHYXIA IN INTRAUTERINE GROWTH RESTRICTION OF THE FETUS- CARDIOTOCOGRAPHY AND ULTRASOUND METHODS OF DIAGNOSIS.
Fetal asphyxia remains an important cause of neonatal morbidity and mortality. The tests in themselves (cardiotocography (NST), sonography, Doppler studies) which are used for antenatal fetus surveillance are aimed at timely diagnosing the signs of the fetus asphyxia. The objective of the current research is to study which modifications in the cardiotocography (NST), arterial and venosus Doppler correlate most strongly with severe asphyxia pH< 7.10 and BE≥12 mmol/l regarding pregnancies which are complicated with intrauterine growth restriction of the fetus. The presence of spontaneous decelerations in the cardiotocography shows sensitivity 81.3%, specificity 97.1%, positive predictive value (PPV) 83.2, negative predictive value (NPV) 98.2%, odds ratio (OR) 260, p< 0.0001, the reversed blood velocity of artery umbilicalis shows sensitivity 58.3%, specificity 96.2%, PPV 63.6%, NPV 95. 3% OR 35.7 p< 0.001, reversed a-wave ductus venosus shows sensitivity 51%, specificity 94.3%, PPV 48% NPV 93.2% OR 16.7, p< 0.001. Concerning pregnant women with intrauterine growth restriction of the fetus the prognostication of severe fetus asphyxia at delivery - pH<7. 10 and BE -12 mmol/I with the highest specificity of antenatal testing is the occurrence of spontaneous decelerations in NST, the reversed blood velocity of umbilical artery and the reversed a-wave ductus venosus in Doppler studies.
