[The management of labor overweight women with intrapartum fetal oxygen saturation monitoring].
OBJECTIVE
Overweight is one of the most common problems that occurs in pregnancy. The aim of this study was to evaluate the usefulness of fetal pulse oximetry during labour and to compare fetal oxygen saturation between cases with pregravid overweight and normal weight.


METHODS
Fetal oxygen saturation was continuously recorded with use of Nellcor N-400 fetal pulse oximeter in 20 cases of pregravid overweight and 30 control cases of normal weight. Distribution of fetal oxygen saturation values during 4 periods of labour was analyzed and compared between the examined groups together with neonatal umbilical artery pH values, Apgar score, birth weight and percentage of ceasarian sections performed.


RESULTS
We noticed statistically important differences in fetal oxygen saturation between analyzed groups. Mean oxygen saturation value was lower in the overweight group, at the end of first stages of the labour (47% vs 52%) and at the second stages (42% vs 46%) We noticed differences in birth weight too. No significant differences in neonatal umbilical artery pH, ceasarian sections, newborns mean 1 minute Apgar score were observed between analyzed groups.


CONCLUSIONS
Fetal pulse oximetry is a a useful method for intensive surveillance of the fetus at risk of hypoxemia during the labour. A lower fetal oxygen saturation value during labor by pregravid overweight were observed.
