Insights
Family Nurture Intervention (FNI) significantly increased frontal brain activity in preterm infants during sleep. This intervention may improve neurodevelopmental outcomes for premature babies.
Area of Science:
- Neonatal Neuroscience
- Developmental Psychology
- Clinical Neurophysiology
Background:
- Preterm infants exhibit altered brain development.
- Family-centered care interventions aim to improve outcomes for vulnerable infants.
- Electroencephalogram (EEG) measures brain activity and can indicate neurodevelopmental status.
Purpose of the Study:
- To evaluate the effect of Family Nurture Intervention (FNI) on EEG activity in preterm infants.
- To determine if FNI influences brain development markers in the neonatal intensive care unit (NICU) population.
Main Methods:
- A randomized controlled trial was conducted in a level IV NICU.
- 134 preterm infants (26-34 weeks gestation) were assigned to standard care or standard care plus FNI.
- EEG recordings were analyzed for regional brain activity across 10 frequency bands at ~35 and ~40 weeks postmenstrual age.
Main Results:
- Infants receiving FNI demonstrated significant increases in frontal EEG power (10-48 Hz) compared to controls.
- These increases ranged from 20% to 36% and were observed during both quiet and active sleep.
- The positive effects were consistent across various subgroups, including gestational age and birth weight.
Conclusions:
- Family Nurture Intervention promotes enhanced frontal brain activity in preterm infants during sleep.
- Increased frontal brain activity is associated with improved neurobehavioral outcomes.
- FNI presents a practical approach to potentially improve outcomes for preterm infants.
Objective:
To assess the impact of Family Nurture Intervention (FNI) on electroencephalogram (EEG) activity in preterm infants (26-34 weeks gestation).
Methods:
Two groups were tested in a single, level IV neonatal intensive care unit (NICU; standard care or standard care plus FNI) using a randomized controlled trial design. The intervention consists of sessions designed to achieve mutual calm and promote communication of affect between infants and their mothers throughout the NICU stay. EEG recordings were obtained from 134 infants during sleep at ∼35 and ∼40 weeks postmenstrual age (PMA). Regional brain activity (power) was computed for 10 frequency bands between 1 and 48 Hz in each of 125 electrodes.
Results:
Near to term age, compared to standard care infants, FNI infants showed robust increases in EEG power in the frontal polar region at frequencies 10 to 48 Hz (20% to 36% with p-values <0.0004). Effects were significant in both quiet and active sleep, regardless of gender, singleton-twin status, gestational age (26-30 or 30-35 weeks) or birth weight (<1500 or >1500 g).
Conclusion:
FNI leads to increased frontal brain activity during sleep, which other investigators find predictive of better neurobehavioral outcomes.
Significance:
FNI may be a practicable means of improving outcomes in preterm infants.
