[Relations between neonatal heart rate variability and the behavioral state].

    Summary

    Neonatal heart rate variability (NHRV) differs based on behavioral state and delivery mode. Cesarean section infants show altered NHRV adaptation in the first 24 hours compared to vaginal delivery.

    Area of Science:

    • Physiology
    • Neonatal Medicine
    • Cardiology

    Context:

    • Investigating the relationship between neonatal heart rate variability (NHRV) and behavioral states in healthy newborns.
    • Comparing NHRV patterns in infants born via normal vaginal delivery versus elective cesarean section.

    Purpose:

    • To analyze how different behavioral states influence NHRV in newborns.
    • To determine if the mode of delivery impacts neonatal adaptation and NHRV patterns.

    Summary:

    • NHRV, analyzed using Long-Term Variability (LTV) and Short-Term Variability (STV) indices, showed distinct patterns across behavioral states (Prechtl's criteria).
    • LTV increased in active quiet states (2 and 4) peaking on day three, while STV changes were inconsistent.
    • Infants delivered via cesarean section (CS) exhibited increased LTV within 24 hours post-birth, suggesting altered neonatal adaptation compared to vaginal delivery.

    Impact:

    • Provides insights into the neurophysiological development of newborns based on behavioral state and delivery method.
    • Highlights potential differences in neonatal adaptation following cesarean section, informing clinical observation and care.
    • Establishes discriminant functions for accurate classification of active quiet behavioral states using NHRV, with 85-100% accuracy.
