Normal capillary refill time is usually less than 2 seconds. In newborn infants, capillary refill time can be measured by pressing on the sternum for five seconds with a finger or thumb, and noting the time needed for the color to return once the pressure is released. The upper normal limit for capillary refill in newborns is 3 seconds.
Is capillary refill time an important warning sign in children?
A capillary refill time (CRT) of 3 seconds or more is an important warning sign for serious illness and risk of death in children, a systematic review of 24 studies on over 53,000 children has concluded.
Is 3 seconds of capillary refill time normal?
A capillary refill time of three seconds or more should be considered abnormal. The results show that an abnormal CRT of 3 seconds or more increases the likelihood of a serious outcome including death and dehydration – however a normal CRT does not make a serious outcome less likely.
How do you measure capillary refilling time in infants?
Informed consent was obtained from a parent of each infant included in the study. For the purpose of this study, capillary refilling time was measured in four body areas: midpoint of the sternum; midpoint of the forehead; palm of the hand; and plantar surface of the heel (in this study—chest, head, palm and heel, respectively).
Can capillary refill time be used as a red flag?
Our results show that capillary refill time is a specific sign, indicating that it can be used as a “red-flag”: children with prolonged capillary refill time have a four-fold risk of dying compared to children with normal capillary refill time. The low sensitivity means that a normal capillary refill time should not reassure clinicians.
How do you assess capillary refill in an infant or child?
Capillary refill time - Press on the finger for five seconds using moderate pressure at an ambient temperature of 20–25 degrees Celsius. A capillary refill time of three seconds or more should be considered abnormal.
What is the capillary refill time for an infant?
The normal value of capillary refilling time (CRT) in healthy neonate is less than three seconds. The major determinants of CRT in healthy neonate are birth weight, radiant warmer and phototherapy.
What does +2 capillary refill mean?
Capillary Refill Time Normal CRT is 1 to 2 seconds. This is consistent with a normal blood volume and perfusion. A CRT longer than 2 seconds is a subjective sign of poor perfusion or peripheral vasoconstriction.
What does capillary refill less than 2 seconds mean?
The normal CRT is <2 seconds; a CRT of >2 seconds suggests poor peripheral perfusion and may be an early sign of shock (Hernández et al, 2020).
When assessing capillary refill in pediatric patients the color should return after?
CRT is the time it takes for colour to return to a capillary bed after pressure has been applied to create blanching of the area. A normal CRT should be between 2-3 seconds when applied centrally, such as to the sternum or the forehead.
What is slow capillary refill?
“Frequent causes of sluggish, delayed or prolonged capillary refill (a refill time >2 seconds) include dehydration, shock, and hypothermia. Shock can be present despite a normal capillary refill time. Children in “warm” septic shock may have excellent (ie, <2 seconds) capillary refill time.”

How do you calculate capillary filling time?
ProcedureStep1. Remove finger rings and nail polish.Step2. The therapist compresses the nail bed until it turns white and records the time taken for the color to return to the nail bed.Step3. It normally takes 3 seconds or less. ... Step4. Always compare to the normal side of the hand or fingers.
How do you chart capillary refill?
To check capillary refill, depress the nail edge to cause blanching and then release. Colour should return to the nail instantly or in less than 3 seconds. If it takes longer, this suggests decreased peripheral perfusion and may indicate cardiovascular or respiratory dysfunction.
Use
Publication
- Published in PLOS One, the review led by Dr Susannah Fleming, a research fellow in the University of Oxfords Nuffield Department of Primary Care Health Sciences, is the first comprehensive and systematic assessment of the diagnostic value of the CRT test for a range of serous outcomes in children worldwide.
Results
- The results show that an abnormal CRT of 3 seconds or more increases the likelihood of a serious outcome including death and dehydration however a normal CRT does not make a serious outcome less likely. The authors conclude that a normal CRT should not be used to rule out serious illness in children, and repeated measurement is important before clinicians should get …
Benefits
- We looked at studies across a variety of outcomes including primary and secondary care, low- and high-income countries, and emergency services. We found that a prolonged CRT acts as a useful red flag in all these different situations. Considering this is a diagnostic tool that doesnt require any sophisticated equipment and can be measured easily in children of all ages, our findings ad…
Epidemiology
- The most convincing data was found for predicting death in settings with particularly high mortality rates, where children with a prolonged CRT had a 4-fold greater risk of dying compared to those with a normal CRT - though this may not generalise well to areas with low mortality. In the studies we looked at in high-income settings, we found abnormal CRT was linked to significa…
Medical uses
- The authors note that CRT specificity may vary for certain diseases, so it was less useful for meningitis than for sepsis, dengue, hypoxia or the need for hospital admission for serious infection.
Funding
- The research was funded by the European Union Seventh Framework Programme. Susannah Fleming was funded by a National Institute for Health Research (NIHR) School for Primary Care Research Fellowship.
