Effect of radiant warmer on transepidermal water loss (TEWL) and skin hydration in preterm infants

Area of Science:

• Neonatal care
• Dermatology
• Pediatrics

Background:

• Preterm infants have immature skin barriers, making them vulnerable to environmental factors.
• Radiant warmers are commonly used for thermal regulation in neonates, but their impact on skin integrity is debated.

Purpose of the Study:

• To assess the effect of radiant warmers on the skin barrier function of preterm infants.
• To compare transepidermal water loss (TEWL) and stratum corneum hydration under radiant warmer versus incubator conditions.

Main Methods:

• Transepidermal water loss (TEWL) and stratum corneum hydration were measured in 30 preterm infants across seven body areas.
• Each infant served as their own control, with measurements taken under both radiant warmer and incubator conditions.

Main Results:

• A significant increase in TEWL was observed only on the forehead and upper back under radiant warmer conditions.
• The overall mean difference in TEWL between radiant warmer and incubator conditions was 15%.
• Stratum corneum hydration levels were not significantly affected by the radiant warmer.

Conclusions:

• The use of radiant warmers does not appear to significantly compromise the skin barrier function in preterm infants.
• Findings suggest that radiant warmers can be safely employed for thermal management in preterm neonates without substantial negative effects on skin barrier properties.
