Hyperaemia and its value in the diagnosis of diseases

Hyperemia is often a simple symptom, which is familiar every person, means non-medical language of "redness". The origin is people don't think about until you see the physician or confinement after endoscopic examination. Then there is doubt and questions: is it good or bad, that could indicate this change?

Hyperemia is the process of overfilling of the peripheral vessels in any area of the body, in the skin or in the internal organ.

• working or functional, caused by the inflow of arterial blood to the organs, muscles, skin, working with the increased load;
• artificial invoked using a thermal physiotherapeutic procedures; artificially created land of blood and its latency, the nature refers to the mixed form;
• vakatnoe — occurs when artificial lowering of barometric pressure over the tissues (in the treatment with the formulation cell;
• vasomotor — called disrupted nervous regulation of arterial vascular tone, spasm is replaced by the extension (the hands in Raynaud's disease);
• inflammatory and increased blood flow through the arteries contributes to the accumulation in the blood kinin substances that improves the flow into the center of mast cells, neutrophils to fight infection; begins as blood, and then goes to the mixed type to stagnation;
• hypostatic — the venous type is associated with weakness of the myocardium, decrease the suction properties of the right atrium and the diaphragm;
• collateral — if trombicula main arterial trunk, the work included the auxiliary branch, it enters the blood in the lesions of ischemia, serves as an auxiliary protective reaction of the body;
• drug — like artificial, but it is called local or General action of drugs (redness of the skin and mucous membranes after intravenous calcium chloride solution, intramuscularly nicotinic acid);
• neuroparalitical — possible Central or peripheral mechanism of the paralysis of the vascular core, the modes of transmission of the pulse of the sympathetic fibers;
• narodnichesky (irritative) — linked to cases of centres or pathways responsible for vasodilation;
• perustamisesta — equal cases equally vasodilator nerves and reduction of excitability of the vasoconstrictor;
• postischemic — fills the plot of land of ischemia during the recovery period;
• toxic is formed due to the influence of toxic substances and poisons received into the body in case of poisoning, is associated with the accumulation of toxins (kidney and liver failure);
• reflex (reactive hyperemia) — is a response to the impact of the foreign irritant withantigen foreign to the body.

At what diseases there is flushing?

Consider special cases of the diagnosis, in which direct participation is such sign as redness.

Therapy and surgery

Inflammation cause of pathological microorganisms (bacteria, viruses, fungi). As it will be limited or will grow into a violent picture of sepsis depends on the immune status. Usually to the affected lesion with arterial blood attracts numerous cells of a leukocytic series.

Some of them operates on the principle killers, and other "clean up" the resulting waste, there are mechanisms of remembering "unfriendly" agent and stimulate the production of specific antibodies. But vascular reaction is always accompanied by a rush of blood, hyperaemia.

When a respiratory infection is detected redness in the throat.

In dermatological practice

Inflammatory hyperemia is observed in acne, furunculosis. Typical skin changes in systemic lupus erythematosus is difficult to explain only one hyperemia. To pathology connected with autoimmune mechanism excessive response to self cells.

Patients dentist

In acute dental pain pulsating nature, the dentist opens the tooth cavity and checks for the presence of hyperemia of the pulp. This is the tissue inside the tooth. Through her feeds and is updated bone. With deep caries cavity is detected with a painful bottom. Hyperemia of the pulp indicates severe inflammation (pulpitis).

So the doctor will not just put a permanent seal. First conduct the treatment with anti-inflammatory drugs, physiotherapy methods.
