Aspects of capillary refilling time (CRT) in newborns, such as pressing time, sites of testing, normal values and difference between observers were assessed. CRT was measured in 280 term newborns, divided into 7 groups of 40 each, varying pressing time (from 1 to 7 s) was applied. CRT was measured in midpoints of forehead and sternum and plantar surface of heel (defined as head, chest and heel). No statistically significant difference was found between 3 and 7 s pressing time groups. The data points of the CRT of the head and chest approached normality, whilst those of the heel were widely scattered. Normal CRT in newborns is <3 s. No significant difference between two observers in head and chest CRT values was found.
对新生儿毛细血管再充盈时间（CRT）的各个方面进行了评估，包括按压时间、测试部位、正常值以及观察者之间的差异。对280名足月儿进行了CRT测量，将其分为7组，每组40名，分别施加不同的按压时间（从1秒到7秒）。在额头中点、胸骨和足跟足底表面（分别定义为头部、胸部和足跟）测量CRT。3秒和7秒按压时间组之间未发现统计学上的显著差异。头部和胸部CRT的数据点接近正态分布，而足跟的数据点分布广泛。新生儿正常CRT小于3秒。在头部和胸部CRT值方面，两名观察者之间未发现显著差异。
