Continuous maternal glucose measurements and fetal glucose and insulin levels after administration of terbutaline in term labor.
Maternal blood glucose and fetal blood glucose and insulin levels were studied in 16 women at full-term labor after administration of terbutaline 250 microgram i.v. The maternal blood glucose level was registered by a continuous blood glucose monitoring unit. In all patients studied, the terbutaline injection was followed by a rise in maternal blood glucose within 15 min, lasting for at least one hour. The fetal glucose levels paralleled those of the mothers, but on a lower level. None of the infants demonstrated hypoglycemia during the first 90 min after birth. We conclude that terbutaline administrated in this way has a direct effect on the maternal blood glucose release, and report that no harmful effects on fetal carbohydrate metabolism could be demonstrated.
