Objective: To investigate the effects of a prefeeding oral stimulation program on the feeding performance of preterm infants.
Methods: A crossover design was used. Nineteen preterm infants who were in the transitional time to full oral feeding served as their own controls. A 5-min oral stimulation program was applied to infants prior to feeding in two of 4 feedings on two consecutive days. Feeding, behavioral state, and physiological parameters of infants in the intervention and control feeding conditions were compared using SPSS software.
Results: There were two significant findings: (1) Compared to the control condition, infants in the intervention condition achieved a greater intake rate in the initial 5 min of the feeding (P = 0.021). (2) After receiving oral stimulation, a higher percentage of infants moved to the drowsy or quiet alert state from sleep or restlessness before feeding, both on Day 1 (P= 0.016) as well as Day 2 (P = 0.016). No significant differences were found in other feeding parameters, feeding-induced physiological changes (peripheral oxygen saturation levels and pulse rate) and behavioral states between two feeding conditions.
Conclusions: Oral stimulation had a modulating effect on the prefeeding behavioral states and short-lived beneficial effects on the feeding efficiency of preterm infants.
