Neonatal blood glucose concentrations in caesarean and vaginally delivered term infants.
BACKGROUND
Little is known about the glucose concentrations at and after birth of infants delivered by caesarean section (CS), when compared with infants born vaginally (VD).


OBJECTIVE
To compare venous cord blood glucose concentrations of term infants born after elective CS to infants born by VD. We studied the null hypothesis that mode of delivery does not affect neonatal blood glucose values.


METHODS
We compared cord blood glucose concentrations in healthy term infants born after VD (n = 16) or by elective CS (n = 21). Glucose concentrations were obtained immediately at birth from the umbilical cord. Kruskal-Wallis was used to compare glucose concentrations and demographic variables between the groups.


RESULTS
Gestational age was 39.6 ± 0.8 weeks in VD group vs. 38.7 ± 0.9 weeks in CS group, and birthweight was 3359 ± 494 vs. 3500 ± 528 g. Cord blood glucose concentration was higher in VD (81.3 ± 16.9 mg/dL) than CS infants (70.3 ± 9.7 mg/dL, p = 0.039). The change in blood glucose concentration over the first 2-h of life differed significantly between the two groups, being an increase in CS versus a decrease in VD infants (-3.5 ± 15.2 vs. -15.4 ± 24.6 mg/dL, p = 0.013).


CONCLUSIONS
Glucose concentrations in VD infants are higher than in infants born by elective CS without labour.
