Facilitating inactive awake states in preterm infants: a study of three interventions

Abstract

Inactive awake behavioral states have been associated with reduced heart rates and more successful feeding in preterm infants. The purpose of this study was to test the efficacy of three different interventions to facilitate these optimal feeding states. Twenty preterm infants (gestational ages 27-33 weeks, M = 31.6, SD = 1.7; birth weights 931-2,140 grams, M = 34, SD = 373) serving as their own controls were randomly administered nonnutritive sucking, nonnutritive sucking plus rocking, and stroking interventions; and a control condition. There were significantly more inactive awake states with the nonnutritive sucking and nonnutritive sucking plus rocking interventions than with the stroking intervention and the control conditions. The results suggest that there are interventions that can help preterm infants in the transition from gavage to oral feeding and potentially shorten their hospital stays.
