To evaluate the hormonal response to stress in healthy preterm infants, we measured concentrations of serum cortisol at baseline and after capillary heelstick. Eleven preterm infants, five girls and six boys, with gestational ages ranging from 30 to 34 weeks, were studied. We measured the serum cortisol concentration before and 30 min after capillary heelstick on days 1, 3 and 7 of life. On days 3 and 7, but not on day 1, the rise in cortisol was significant (p = 0.02 and 0.04, respectively). The reduced response on day 1 can probably be explained by the significantly higher baseline concentrations. We suggest that a test like this can be useful in evaluating the hormonal stress response in preterm as well as full-term infants.
