How does non-nutritive sucking support infant feeding?

Area of Science:

• Neonatal care
• Developmental pediatrics
• Speech and language pathology

Background:

• Non-nutritive sucking (NNS) is often perceived to accelerate oral feeding and early language development in premature infants.
• The role of NNS in supporting parental confidence and facilitating earlier hospital discharge requires further investigation.
• Premature infants (26-35 weeks gestation) with no significant difficulties were studied to clarify NNS effectiveness.

Purpose of the Study:

• To determine the effectiveness of non-nutritive sucking (NNS) on the development of full oral feeding and early language skills in premature infants.
• To assess if NNS, as a strategy to support parental identification of infant cues, impacts infant management and hospital discharge timing.

Main Methods:

• A randomized controlled study involving 59 premature infants (26-35 weeks gestation) assigned to three groups: NNS pre-tube feeding, NNS during tube feeding, and a control group.
• Data collected on days to full oral feeding, hospital length of stay, sucking patterns, and language skills at 6 months follow-up.
• Statistical analyses included chi-square tests to compare outcomes between groups.

Main Results:

• No significant differences were found in the number of days to achieve full oral feeding between NNS groups and the control group (p=.115).
• A significant reduction in the number of hospital days was observed in the NNS groups compared to the control group (p=.022).
• Improvements in sucking patterns were noted across all groups, with no significant differences in receptive or expressive language skills at 6 months.

Conclusions:

• Non-nutritive sucking (NNS) does not significantly impact the transition to full oral feeding or later language development in premature infants.
• NNS, when used to support parental recognition of infant communication and readiness cues, is associated with a shorter hospital stay.
• Further research should explore the mechanisms by which NNS enhances parental confidence and facilitates earlier discharge.
