The meta-analysis highlighted the significant positive effect of non-nutritive sucking (NNS) on the transition from gavage feeding to oral feeding in preterm infants. This effect also had a positive impact on the time from onset of oral feeding to full oral feeding and on the length of the hospital stay. None of the studies revealed serious NNS- related side effects.

Background

As a general rule, preterm infants are unable to feed orally. Therefore, they are usually fed via a nasogastric tube. They are also given a soother developed specifically for preterm infants. Infants need coordinated sucking, swallowing and breathing to feed adequately. This ability starts to develop by 28 weeks gestation with full coordination being achieved between weeks 32 and 34. Infants born before 32 weeks gestation are usually not able to feed effectively from the breast or a bottle. Last but not least, non- nutritive sucking has a calming effect on preterm infants.

Methodology

The authors of the meta-analysis identified twelve eligible studies enrolling a total of 746 preterm infants in searches updated to February 2016. The findings of this meta- analysis must be considered limited. The authors recommend additional, large and randomized studies.

Results

  • Soothers are frequently used in preterm infant gavage feeding to promote coordinated sucking and swallowing.
  • The use of soothers to support sucking shortens the transition period to full oral feeding and reduces the time spent in hospital.
  • A stable sucking and swallowing cycle in full-term babies indicate neurobiological stability and maturity.
  • NNS is an excellent method for helping the preterm infant to develop physiological homeostasis and positive behavior.
  • Pneumonia, bradycardia, hypoxia and fatigue can develop if preterm infants swallow incorrectly.
  • NNS provides an opportunity to experience feeding without the added stress of having to swallow liquids.
  • NNS is also one of the first steps in promoting self-soothing and self-regulation in preterm infants.
