Area of Science:

  • Neonatal physiology
  • Autonomic nervous system function
  • Bioelectrical signal analysis

Background:

  • Skin conductance (SC) changes reflect sympathetic nervous system activity and central arousal.
  • Preterm infants exhibit SC changes measurable by sensitive alternating voltage apparatus.
  • Accurate analysis of SC in neonates is crucial for understanding their physiological state.

Purpose of the Study:

  • To develop a software program for analyzing skin conductance (SC) in preterm infants.
  • To enable objective quantification of SC parameters in neonatal research.
  • To facilitate the study of autonomic responses in premature infants.

Main Methods:

  • Software designed to calculate SC wave number, mean amplitude, and mean SC changes.

  • Comparison of software analysis with manual wave counting using varied wave parameter settings.
  • Optimization of parameters for minimum amplitude, maximum slope, and minimum width.

    • Main Results:

    • Optimal minimum amplitude for SC waves identified as 0.015 microS.
    • Maximum slope parameter showed consistent results across 1, 2, or 5 microS/s.
    • Optimal wave width for analysis was determined to be unlimited.

    Conclusions:

    • The developed software program effectively analyzes skin conductance in preterm infants.
    • This tool simplifies and standardizes SC measurement in neonatal populations.
    • The software facilitates research into the autonomic nervous system of premature infants.
