Prior to obtaining imaging, adequate pain control should be provided. Consideration should be given to imaging joints above and below an injury humeral radiographs will generally adequately visualize the elbow and shoulder joints, but dedicated imaging of those sites should be performed if clinically indicated. , Comparative views are generally not indicated. , Two-view imaging (AP and lateral projections) of the affected extremity is generally sufficient when evaluating pediatric long bone injuries and is appropriate to diagnose humeral shaft fractures in these patients. The proximal humerus can be visualized with a shoulder series and typical views include anteroposterior (AP), scapular Y, and axillary views. A child may not be able to indicate exactly where the source of their pain might be and shoulder imaging may be obtained rather than dedicated imaging of the humerus if a shoulder injury is initially suspected. The classification of humerus fractures depends on their location: proximal physeal fractures are classified using the Salter-Harris Classification, with the majority being Salter-Harris type I or II fractures, whereas humeral shaft fractures are classified by angulation, displacement, and location. There are no lacerations or abrasions of the skin. He has brisk capillary refill and a strong radial pulse. There is no apparent weakness or numbness. His vital signs are age appropriate and there is no obvious injury other than mild edema and tenderness of his proximal right humerus. There is no reported loss of consciousness and he denies neck pain, abdominal pain, back pain, or elbow pain. Prolonged capillary refill time may also suggest peripheral artery disease.A 6-year-old boy presents with right upper arm and shoulder pain after falling off a horse while riding at a brisk trot. What does poor capillary refill mean?Ī prolonged capillary refill time may be a sign of shock and can also indicate dehydration and may be a sign of dengue hemorrhagic fever and decreased peripheral perfusion. The CRT in newborns is shorter in those nursed in incubators or under radiant heaters. The CRT of healthy children in a warm environment (mean 25.7) was x26lt 2 seconds but only 31% had a similar measurement in a cold environment (mean 19.4). Ambient, skin, and core temperature affect CRT measurement. What causes increased capillary refill time? Children in warm septic shock may have excellent (ie, x26lt 2 seconds) capillary refill time. Shock can be present despite a normal capillary refill time. It is used to monitor dehydration and the amount of blood flow to tissue What causes decreased capillary refill?įrequent causes of sluggish, delayed or prolonged capillary refill (a refill time x26gt 2 seconds) include dehydration, shock, and hypothermia. The capillary nail refill test is a quick test done on the nail beds. What does a capillary refill test indicate? Recently, temperature has been reported to affect capillary refill time and therefore temperature may interfere with accurate bedside peripheral blood perfusion evaluation. Does temperature affect capillary refill?Ĭapillary refill time has been accepted as a method to manually assess a patient’s peripheral blood perfusion.

What causes poor capillary refill?įrequent causes of sluggish, delayed or prolonged capillary refill (a refill time x26gt 2 seconds) include dehydration, shock, and hypothermia. CRT should always be judged within the clinical context, and is rarely useful in isolation. What affects capillary refill time?ĬRT can be affected by ambient temperature, ambient light, the site of measurement, the amount of pressure applied to the capillary bed, and is also subject to interobserver variability. Pallor and prolonged refill time suggest heart failure or reduced blood pressure with reactive vasoconstriction. Membrane pallor suggests poor perfusion or anemia (evaluate for intestinal parasitism, especially hookworm infection). Mucous Membranes Normal membranes are pink with a capillary refill time of x26lt 2 seconds. A prolonged CRT may indicate the presence of circulatory shock What does poor capillary refill indicate? A prolonged CRT may indicate the presence of circulatory shock What does prolonged capillary refill mean?Ĭapillary refill time (CRT) is a measure of the time it takes for a distal capillary bed, such as those found in the fingers, to regain colour after pressure has been applied to cause blanching. Capillary refill time (CRT) is a measure of the time it takes for a distal capillary bed, such as those found in the fingers, to regain colour after pressure has been applied to cause blanching.
