What is the cause of sudden shock?

summary

Generally speaking, if people suddenly want to shock in peacetime, they need to quickly find out the reason for symptomatic treatment. Then, what is the cause of sudden shock? It can be considered from the following three aspects.

What is the cause of sudden shock?

Hypovolemic shock hypovolemic shock is intravascular volume insufficiency, which leads to ventricular insufficiency and decreased stroke volume. If the increase of heart rate can not be compensated, it can lead to decreased cardiac output（ 1) Hemorrhagic shock is a syndrome of peripheral circulation failure caused by massive blood loss and rapid decrease of effective circulating blood volume. Generally, when the blood loss within 15 minutes is less than 10% of the total blood volume, the body can compensate. If the rapid blood loss exceeds about 20% of the total blood volume, shock can be caused（ 2) Burn shock large area burn, accompanied by a large amount of plasma loss, can cause burn shock. The early stage of shock is related to pain and hypovolemia, and the late stage may be secondary to infection and develop into septic shock（ 3) Traumatic shock, which is associated with pain and blood loss.

Vasodilative shock vasodilative shock is usually due to insufficient intravascular volume caused by vasodilation. Its circulating blood volume is normal or increased, but the heart is not filled and tissue perfusion is insufficient（ 1) Septic shock is one of the most common types of shock in clinic ˉ Bacilli infection is the most common. According to the characteristics of hemodynamics, it can be divided into low dynamic shock (cold shock) and high dynamic shock (warm shock)（ 2) When the body sensitized by anaphylactic shock comes into contact with the antigen substance again, it may have a strong allergic reaction, make the volume vessel dilate, increase the capillary permeability, and appear diffuse non fibrin thrombus. The decrease of blood pressure and poor tissue perfusion may affect multiple organs. (3) neurogenic shock, sympathetic nervous system acute injury or drug block can cause the affected nerve dominated arteriole dilation, blood volume increase, relative blood volume deficiency and blood pressure drop; This kind of shock has a good prognosis and can often be cured by itself.

Cardiogenic shock cardiogenic shock refers to the state of insufficiency of effective circulation blood volume, hypoperfusion and hypotension caused by rapid decrease of cardiac output caused by impaired cardiac pump function or impaired cardiac blood flow outlet and insufficient compensatory rapid vasoconstriction. Cardiogenic shock includes shock caused by heart disease, cardiac compression or obstruction.

matters needing attention

Shock is caused by temporary hyperemia or temporary lack of blood circulation. Therefore, we must not eat stimulating food or food that is easy to make people impatient, so as to avoid serious consequences due to temporary negligence.
