Abstract.
Objectives. To identify the prognostic Doppler parameters of the fetoplacental blood flow after 32 weeks of gestation associated with unfavorable perinatal outcomes and pathological acid-base condition of the newborns’ blood for determining the optimal time of delivery in intrauterine growth restriction.
Material and methods. The resistance indices of the umbilical artery (RIUA), the middle cerebral artery (RIMCA) and cerebroplacental ratio (CPR) after 32-40 weeks of gestation were studied in 71 women with fetus growth restriction (the main group) and 21 women who gave birth to healthy full-term babies (the control group). The acid-base state of the blood was studied in 5-8 minutes of newborns’ life.
Results. It has been established that for the detection of fetal acidosis after 32 weeks of gestation in case of intrauterine growth restriction the values of RIMCA<5% and CPR<1 are diagnostically informative.
Conclusions. The registration of RIMCA<5% with CPR>1 after 32 weeks of gestation in case of intrauterine growth restriction requires daily fetal monitoring, but when 2D Doppler signs of blood circulation centralization (CPR<1 with RIMCA<5%) appear, the delivery after 34 weeks is necessary.
Key words: 2D dopplerography, fetoplacental blood flow, acid-base state of the blood.
