Insights
Neurologic issues like brain bleeds are rare in moderately preterm infants. Feeding difficulties, however, are the main concern, stemming from challenges in coordinating suck, swallow, and breathing.
Area of Science:
- Neonatal neurology
- Developmental pediatrics
Background:
- Very preterm and extremely preterm infants face significant neurologic risks, including intracranial hemorrhage, white matter injury, and apnea.
- These severe morbidities are less frequent in moderately preterm and late preterm infants.
Purpose of the Study:
- To investigate the spectrum and frequency of neurologic morbidities in moderately and late preterm infants.
- To identify the primary neurologic challenges faced by these infants.
Main Methods:
- Review of existing literature and surveillance data on neuroimaging in preterm infants.
- Analysis of reported frequencies of specific neurologic conditions.
- Identification of feeding difficulties as a key outcome measure.
Main Results:
- Germinal matrix hemorrhage-intraventricular hemorrhage and white matter injury occur infrequently in moderately and late preterm infants, though precise frequencies are difficult to ascertain due to selection bias in neuroimaging.
- Feeding difficulties, related to the integration of suck, swallow, and breathing, represent the most common neurologic morbidity in this population.
Conclusions:
- While severe neurologic injuries are uncommon, moderately and late preterm infants frequently experience feeding challenges.
- The developmental integration of suck, swallow, and breathing is a critical factor in the neurologic well-being and feeding success of these infants.
Abstract:
Common neurologic morbidities encountered in very preterm and extremely preterm infants (intracranial hemorrhage, white matter injury and periventricular leukomalacia, and apnea of prematurity) are much less common in moderately preterm and late preterm infants. The frequency of germinal matrix hemorrhage-intraventricular hemorrhage and white matter injury are reported to be low, but selection bias in neuroimaging surveillance prevents ascertainment of precise frequencies. The major neurologic morbidity of moderately and late preterm infants is feeding difficulty reflecting developmental integration of suck, swallow, and breathing.
