OBJECTIVE
To evaluate the effect of radiant warmers on skin barrier function in preterm infants.
METHODOLOGY
Transepidermal water loss (TEWL) and stratum corneum hydration were measured in 30 preterm infants (birth weight 825 to 2220 g) in seven body areas: forehead, upper back, cubital fossa, palms, soles, abdomen, and inguinal region. Measurements were performed under radiant warmer and incubator conditions. Each patient served as his/her control.
RESULTS
TEWL was significantly higher in the radiant warmer compared to the incubator condition in only two areas: forehead and back. The overall mean difference in percentage TEWL between the conditions was 15%. Stratum corneum hydration was not affected by the radiant warmer.
CONCLUSIONS
The use of radiant warmers does not significantly decrease barrier function in the preterm infant.
目的
评估辐射保暖台对早产儿皮肤屏障功能的影响。
方法
对30例早产儿（出生体重825至2220克）的七个身体部位进行经皮水分流失（TEWL）和角质层水合作用测量，这些部位包括前额、上背部、肘窝、手掌、脚底、腹部和腹股沟区。测量在辐射保暖台和暖箱条件下进行。每位患者均作为自身对照。
结果
仅在前额和背部这两个部位，辐射保暖台条件下的TEWL显著高于暖箱条件。两种条件下TEWL百分比的总体平均差异为15%。角质层水合作用不受辐射保暖台影响。
结论
使用辐射保暖台不会显著降低早产儿的屏障功能。
