Capillary Refill Time

Abstract: Capillary refill time (CRT) is widely used by health care workers as part of the rapid, structured cardiopulmonary assessment of critically ill patients. Measurement involves the visual inspection of blood returning to distal capillaries after they have been emptied by pressure. It is hypothesized that CRT is a simple measure of alterations in peripheral perfusion. Evidence for the use of CRT in anesthesia is lacking and further research is required, but understanding may be gained from evidence in other field… Show more

“…Capillary refill time can reflect perfusion of the replanted digit (Pickard et al, 2011), but it is indirect for assessment of arterial blood flow. Walaszek and Zyluk (2008) assessed the blood flow of the anastomosed arteries using Doppler ultrasound after digital replantation.…”

“…El TRC es definido como el tiempo que se requiere para retomar la coloración inicial al ejercer una presión en un lecho capilar distal, preferiblemente, despigmentado (Pickard et al 2011). Con un valor fisiológico inferior a 2seg, este parámetro brinda información sobre el estado de perfusión periférica (Stephenson, 2014).…”

“…La interpretación del TRC, se puede sesgar por factores, como la edad del perro, la temperatura corporal, la luz ambiental, la presión de aplicación digital y el grado de variabilidad intra e interobservador (Pickard et al 2011); no obstante, estos factores se tuvieron en cuenta al momento de plantear el diseño metodológico del estudio, logrando homogenizar las variables, mediante el uso de animales adultos jóvenes, sin evidencia de hipo o hipertermia trasanestésica o presión gingival controlada en tiempo, lo cual, permitió minimizar su aparición. Floriano et al (2016) estudiaron el efecto del isoflurano a diferentes concentraciones alveolares sobre la función microcirculatoria en perros y encontraron que el efecto vasodilatador de este gas anestésico tiene una relación benéfica sobre la perfusión periférica, ya que los valores del TRC se mantienen estables o pueden disminuir al momento de la valoración, hallazgos que concuerdan con resultados de este estudio, puesto que en el periodo anestésico el TRC fue menor frente al periodo preanestésico.…”

“…This sensor design enables CRT measurement on any part of the subject's body, as it is based on reflectance geometry [23]. However, these designs did not take the blanching pressure into consideration, which is a limitation as the duration and strength of the blanching pressure can influence the measured CRT [10,24]. Therefore, simultaneous recording of the applied pressure and PPG can be beneficial in classifying normal and abnormal CRT.…”
