In this study the investigators examine the effects of intraoperative oxygen administration to the mother on certain enzyme functions of the newborn. With this object blood samples are taken from the newborn's umbilical chord - which is otherwise a routine practice at the investigators clinic - and the mother's radial artery in parallel with umbilical clamping and cutting for blood gas and reactive oxygen species analyses. Samples are analyzed locally in a properly equipped laboratory.
Whole-blood superoxide and hydrogen peroxide production was measured from the newborn's umbilical chord.

Maternal hyperoxia
We measured arterial blood gas parameters of the mother from radial artery.
Time frame: through study completion up to two years
Alterations in newborns' enzyme functions due to maternal hyperoxia
We measured umbilical vein reactive oxygen species (ROS) of the newborn.
Time frame: through study completion up to two years
