Summary

Pain expression in preterm infants is linked to their postconceptional age (PCA) and length of stay (LOS). These factors influence how infants react to pain, highlighting the need for careful pain management.

Area of Science:

  • Neonatal care
  • Pediatric pain research
  • Infant development

Background:

  • Preterm infants exhibit unique pain responses.
  • Systematic pain evaluation and treatment are crucial for this population.
  • Understanding pain expression aids in optimizing care for vulnerable infants.

Purpose of the Study:

  • To characterize pain expression in former preterm infants during their first year.
  • To investigate the influence of clinical factors on pain indicators.
  • To provide data for improved pain management strategies in this cohort.

Main Methods:

  • Utilized Modified Behavioral Pain Scale (MBPS) and Visual Analogue Scale (VAS).
  • Collected data on crying time and heart rate during immunizations.

  • Analyzed the impact of postconceptional age (PCA), surgery, ventilation, fentanyl, and length of stay (LOS) on pain parameters.

    • Main Results:

    • 121 procedures in 49 infants were analyzed.
    • Significant correlations found between PCA and heart rate responses.
    • Length of stay (LOS) correlated with crying time, suggesting cumulative pain effects.

    Conclusions:

    • Postconceptional age (PCA) influences heart rate changes, reflecting maturation.
    • Length of stay (LOS) impacts pain expression, possibly due to cumulative procedural pain.
    • Findings underscore the importance of considering developmental and cumulative factors in infant pain assessment.
