title: [Influence of maternal position during delivery of fetal oxygen saturation].
abstract: The aim of the study is to investigate the alterations in fetal oxygen saturation during right lateral, supine and left lateral maternal position. Thirty six women at term are included--during the first stage of normally progressing labour. Simultaneous monitoring is carried out of fetal heart rate, uterine contractions, fetal oxygen saturation and maternal arterial blood pressure for a certain period of time in different maternal positions. It was established, that fetal oxygen saturation values are lowest in the supine position, still remaining in physiological ranges--47.1 +/- 10.2. If supine syndrome develops, fetal oxygen saturation values decrease significantly: 23%, 25%.
