Material: Fulfilled examination included cardiotocographia, ultrasound and Doppler, biochemical blood analyses and O₂ and CO₂ levels and oxygen transport in fetus hord. First group consisted of 49 newborns delivered with asphyxia of different severity, the second one consisted of 84 newborns delivered with Apgar score 8-9.

Results: Analysis of cardiotocogramm revealed deviation from normal values in 28,6% in the first group. Utero-placental and fetus-placental circulation was reduced in 24,5% by Doppler made 1-2 days before delivery and hord loop around fetus neck was found in 50% by ultrasound. Such changes in the second group was noted 3 times rare.

Time from the beginning of the operation to delivery was higher on 2,2 min. in the I group than in the II one. 29% of newborns form the I group suffered from intrauterine infectious disease, that was 2,5 times higher than in the I group.

Conclusions: Reasons of newborns asphyxia, firstly, was the result of intrauterine fetus condition before the delivery and it could be suggested that anesthesia and/or operative procedure by itself break uterine-placental-fetus circulation because changes of fetal hard rate were registered only in 30% of cases.
