Insights

Most children born very preterm develop significant scarring by school age, even with modern neonatal intensive care. This long-term scarring affects 90% of assessed children, impacting their quality of life.

Area of Science:

  • Neonatal Medicine
  • Pediatric Surgery
  • Dermatology

Background:

  • Modern neonatal intensive care has improved survival rates for very preterm infants.
  • The long-term consequences of neonatal intensive care, specifically scarring, are not well-documented.

Purpose of the Study:

  • To assess the prevalence, pattern, and extent of scarring in children born very preterm.
  • To investigate the relationship between scarring and factors like sex and ethnicity.

Main Methods:

  • Observational cohort study of 129 children born <30 weeks' gestation or <1500 g.
  • Children examined at 7 years' corrected age.
  • Documentation of scar presence, size, number, and distribution.

Main Results:

  • 90% of children exhibited scarring, with 81% having multiple scars.
  • 60% had large scars, and 75% had scars in more than one body area.
  • Scarring was more prevalent in boys and non-European children.

Conclusions:

  • Very preterm children frequently experience extensive scarring into school age.
  • Neonatal intensive care, despite advancements, is associated with significant long-term scarring.
  • Further research is needed to understand and mitigate this scarring burden.
