Abstract

Normal physiological childbirth is impossible without uterine contractions. Periodic uterine contractions during vaginal delivery inevitably cause temporary periods of intrauterine vasoconstriction and decreased delivery of arterial blood and oxygen both to the uterus itself and to the placenta and to the fetus inside the uterus. Moreover, the stronger and longer the uterine muscle contractions develop, the stronger and for a longer period they squeeze the uterine vessels and reduce blood flow in them. Therefore, short periods of uterine and placental ischemia are inevitable in natural childbirth, just as short, repeated periods of intrauterine hypoxia are inevitable. Consequently, natural intrauterine hypoxia is a physiological phenomenon that accompanies the birth of every child in a physiological childbirth, and every fetus is normally prepared to withstand such a test of hypoxia. However, an excessively long period of fetal hypoxia and/or exhaustion of fetal adaptation reserves to hypoxia can cause hypoxic damage to brain cells and fetal death. Recent advances in the diagnosis of fetal intrauterine hypoxia, assessment of fetal resistance to hypoxia, and new clinical strategies based on these findings are presented.
