The capillary refill test (CR test) is often used in emergency care, and the capillary refill time (CR time) is used to assess a patient's circulatory condition. The objective of this study was to investigate if repeated CR tests affect CR time.
Thirteen healthy volunteers had repeated CR tests performed on the sternum, forehead, and fingers. The tests were filmed using polarized reflectance spectroscopy and dedicated software for objective quantification of the CR time.
There were no statistical differences between the first CR test in a series and the following. However, there were statistically significant differences in CR time between the different anatomical sites.
Repeated CR tests, separated by a minimum of 2 min, do not affect CR time in healthy volunteers. The site where the test is performed is of importance for CR time.
毛细血管再充盈试验（CR 试验）常用于急救护理，毛细血管再充盈时间（CR 时间）用于评估患者的循环状况。本研究旨在探讨重复 CR 试验是否会影响 CR 时间。
13 名健康志愿者在胸骨、额头和手指上重复进行 CR 试验。使用偏振反射光谱法对试验进行拍摄，并使用专用软件对 CR 时间进行客观量化。
在一系列重复 CR 试验中，第一次与后续的试验之间没有统计学差异。然而，不同解剖部位的 CR 时间存在统计学差异。
在健康志愿者中，至少间隔 2 分钟重复进行 CR 试验不会影响 CR 时间。试验进行的部位对 CR 时间很重要。
