The child’s fever and purple fingers are considered to be caused by vasoconstriction, rapid increase in body temperature, myocarditis, sepsis and other factors.
1. Vasoconstriction: when a child has a fever, the body’s ability to dissipate heat will be reduced, which will cause the surrounding blood vessels to constrict, thus causing local blood circulation obstacles, resulting in the symptoms of the child’s fever and purple fingers.
2. Sharp rise in body temperature: when a child has a fever due to various reasons, it will cause dysfunction in the central thermoregulatory system, which will trigger a sharp rise in body temperature, so that the blood of the whole body will flow back to provide blood for the brain, the heart and other important organs, which will reduce the blood in the endings of the extremities, and will not be able to provide sufficient oxygen for the hand tissues, and the symptom of purplish fingers will appear.
3. Myocarditis: If the child is infected with Coxsackie group B virus, cytomegalovirus, etc., the virus will stimulate the thermoregulatory center, causing fever, but also lead to damage to the myocardium and blood vessels, thus affecting the blood circulation, resulting in the end of the venous blood return obstacles, the symptoms of purple fingers.
4. Septicemia: If the baby has an infection in any part of the body, it will lead to the continuous invasion of toxic toxins and germs into the blood circulation, thus causing systemic infection, resulting in vascular tone and blood circulation disorders, thus causing the symptoms of purple fingers with fever.
The child’s fever fingers purple, there may also be other reasons, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
