Abstract

Objective: to evaluate the differences in neonatal scores (pH and Apgar in newborns) among women who gave birth in the delivery room of the Hospital Universitario de Burgos with and without epidural analgesia (EA).
Method: a retrospective cohort study in 15,506 normal deliveries managed between 2002 and 2015 (9,739 with and 5,767 without AE). The dependent variables were: fetal umbilical artery pH (< 7.10), Apgar at 1 minute (< 7), Apgar at 5 minutes (< 7). The non-parametric Mann-Whitney U test and the Chi-Square Test were used for bivariate analysis.
Results: the mean pH was 7.26 and 7.23, for the groups without EA and with EA respectively (p< 0.0001). The proportion of pH< 7.10 was 2.7% and 4.3%, for the groups without EA and with EA respectively (p< 0.0001). The mean Apgar score at 1 minute was 8.88 and 8.79, for the groups without EA and with EA respectively (p< 0.0001). The proportion of Apgar at 1 minute < 7 was 1.1% and 2.4%, respectively for the groups without EA and with EA (p< 0.0001). The mean Apgar score at five minutes was 9.92 and 9.87, respectively for the groups without EA and with EA (p < 0.0001). The proportion of Apgar at five minutes < 7 was 0.1% and 0.2%, respectively for the groups without EA and with EA (p= 0.045).
Conclusions: the group of women with EA gave birth to babies with a lower pH, and lower Apgar score at 1 minute and at 5 minutes. The use of epidural analgesia was associated with worse neonatal results.
