What is the cause of shock?

summary

Shock is a complex syndrome of systemic microcirculation dysfunction and serious disturbance of vital organs due to the sharp decrease of effective circulating blood volume, extensive, continuous and significant reduction of tissue blood perfusion after the invasion of strong pathogenic factors. At this time, the body function lost compensation, tissue ischemia and hypoxia, neurohumoral factor imbalance. Its main characteristics are: insufficient microcirculation perfusion in important organs, metabolic disorder and dysfunction of various systems of the whole body. What is the cause of shock? Let's talk about it

What is the cause of shock?

(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.

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).

matters needing attention

It must be noted that no matter how severe the shock is, do not give the patient any drink or medication during emergency treatment, so as to avoid choking and causing dyspnea. Let them drink some warm water after they wake up, and especially remind patients to keep warm and rest.
