Objective. The aim of our data is to reveal the method of prognosis abnormal perinatal outcome, using combination US and Doppler results in uncomplicated pregnancies at 40 weeks and beyond. Design.1020 uncomplicated pregnant women at 40 weeks and beyond were examined 48 hours before delivery. We analyzed fetus’s condition during labor and just after. Setting. According these dates all women were divided into 3 groups after amniotic index(AI)and pulsatility indices(PI) in the middle cerebral artery(MCA). Population.260 women were included in the study because they met the inclusion criteria. Methods.All women were divided into 3 groups (group 1 - PI>0.835, any value of AI, group 2-AI >85, PI ≤ 0.835, group 3- AI ≤ 85 and PI ≤ 0.835).We analyzed fetus’s condition during labor and just after delivery (Apgar score <=7 and >7 on the 1st minute). Result. We’ve got trigger level for pulsatility index (PI) as 0.835, if we had PI less than that threshold cases of emergency cesarean section increases in 2,12 times, if PI less than 0,835 in combination with Amniotic Index(AI) 85 and less in 5,28 times. If PI =<0,835 risk of newborns having Apgar 7 and less increases in 1,18, but in combination with AI =<85 in 4,72 times. Conclusion. In results we found out the following data: low PI in the MCA may be parameter which cans prognoses fetus distress. Combination of PI reduce with low AI increases its specific and can use in practical ways to avoid hypoxic brain damage during labor.

Objective The aim of our data is reveal correlation between Doppler in the Middle Cerebral Artery and fetal suffering during labor in uncomplicated pregnancies at 40 weeks and beyond. Design 1020 uncomplicated pregnant women at 40 weeks and beyond were examined by Doppler 48 hours before delivery. Population 260 women were included in the study because they met the inclusion criteria. Methods All women were divided into 2 groups according to fetus distress during labor (vaginal delivery and emergency Cesarean Section caused by fetal distress). And according to newborn’s condition just after delivery (Apgar score <=7 and >7 on the 1st minute) Result In group of women with caesarean section caused by fetal distress pulsatility indexes were significant lower, than in group of women with vaginal labor (PI=1,12 and 0,98 respectively P< 0,01; CPR 1,44 and 1,26 respectively P< 0,01). We found out trigger level for pulsatility indexes as 0.835, if pulsatility indexes less 0.835 we have adverse perinatal outcome during labor. When PI =< 0,835 fetal distress were in 66,7% cases, if PI > 0,835 in 39,1% cases (P<0,001;OR= 3,1). When PI =< 0,835 newborns had Apgar =< 7 in 37,5% and Apgar more than 8 in 20,3% (P< 0,01;OR-2,3) Conclusion Pulsatility indexes in Middle Cerebral Artery can be an indicator of fetal distress and can be useful as a marker of its poor outcome. On the basis of these, it is possible to identify groups of risk of women with gestation age of more than 40 weeks.
