Dense red spots on the back of the hand

If there are dense red spots on the back of your hands, you should be careful. It may be caused by the increased fragility of capillaries, which can easily lead to bruises. At this time, small blood vessels are easily damaged, causing some blood overflow, which often appears on the skin as small red pigments or blue-purple bruises. This situation is called purpura in traditional Chinese medicine, and you should go to the hospital for examination in time.

What is purpura

The name of a disease in traditional Chinese medicine. Also known as purpura, it is characterized by blood overflowing under the skin and mucous membranes, resulting in the appearance of petechiae and ecchymoses that do not fade when pressed. It is one of the common hemorrhagic diseases in children. It is often accompanied by nosebleeds, bleeding from the teeth, and even vomiting blood, blood in the stool, and blood in the urine. This disease belongs to the category of blood syndrome. The diseases and syndromes recorded in ancient Chinese medical books such as "grape plague", "muscle bleeding" and "spot poison" have similarities with this disease. This disease includes allergic purpura and thrombocytopenic purpura in Western medicine. The age of onset of Henoch-Schönlein purpura is mostly 3-14 years old, especially school-age children, more common in males than in females, and more common in spring. The age of onset of thrombocytopenic purpura is mostly 2-5 years old, with no difference in the incidence between boys and girls. The mortality rate is about 1%, and the main cause of death is intracranial hemorrhage.

Pathogenesis

Because children's yin and yang are immature, their qi and blood are not sufficient, and their defenses against external diseases are not strong, they are affected by external pathogens of the season, and the six qi are all transformed into fire and accumulated between their skin, fur and muscles. The evil wind-heat fights against the qi and blood, the heat damages the blood vessels, forces the blood to flow abnormally, overflows from the vessels, seeps under the skin, and causes purpura. If the evil is severe, it can also damage the yin meridians, causing blood in the stool, blood in the urine, etc. If blood heat runs rampant and stagnates in the intestinal tract, it can cause severe abdominal pain. If dampness is retained in the joints, local swelling and pain will occur, and flexion and extension will be difficult. If a child's congenital endowment is insufficient, or the disease prolongs for a long time, it will consume Qi and damage Yin, which may lead to Qi deficiency and Yin damage, and the condition may turn from real to virtual, or even a mixture of real and virtual. If Qi is deficient, it will have no power to control blood, so blood will not flow along the normal path and will overflow outside the vessels. If Yin is deficient and fire is inflamed, blood will move with the fire and seep outside the vessels, both of which can cause recurrent attacks of purpura.

prevention

1. Actively participate in sports activities to enhance physical fitness and improve disease resistance. 2. Try to find out the various causes of allergic purpura as much as possible. Actively prevent and treat upper respiratory tract infections, control tonsillitis, tooth decay, and sinusitis, expel various parasites in the body, and avoid foods and drugs that are likely to cause allergies. 3. For thrombocytopenic purpura, attention should be paid to preventing respiratory tract infections, measles, chickenpox, rubella and hepatitis, otherwise it is easy to induce or aggravate the disease.

Nursing

1. During the acute phase or when the amount of bleeding is heavy, the child should rest in bed, limit his or her activities, and eliminate his or her fear and tension. 2. Avoid external injuries, falls and collisions to prevent bleeding. 3. When the platelet count is lower than 20x109 times/L, closely observe the changes in the condition to prevent various traumas and intracranial hemorrhage. 4. The diet should be light, nutritious and easy to digest. Those who suffer from vomiting blood or bloody stool should eat a semi-liquid diet and avoid hard food and coarse fiber food. Avoid spicy food. Sons with thrombocytopenic purpura can eat more foods such as peanuts with skin and red dates.
