The principles of first aid in shock can be summarized in the following aspects: 1, first aid stage, this time the main goal of treatment is to maximize the maintenance of the patient’s vital signs are stable, to ensure that the blood pressure, heart rate, and cardiac output is maintained in the normal or safe range, in order to save life; 2, optimize the adjustment stage, the main goal of treatment is to increase the supply of cellular oxygen. The first stage of resuscitation is mainly circulatory resuscitation, and this stage belongs to respiratory resuscitation. Through the respiratory movement of oxygen reserves to the cells in the blood, and then transported to various tissues and organs, oxygen release, to promote metabolism, the maintenance of the respiratory chain is the main goal of the second stage of the optimization and adjustment stage; 3, the stabilization stage, the therapeutic goal is to prevent organ failure. Because early blood flow decline may have begun to appear organ dysfunction, this time to reverse organ dysfunction and prevent the aggravation of organ dysfunction belongs to the main goal of this stage; 4, after the previous three phases of treatment, the final stage is the descending ladder treatment. At this time, the goal of treatment is to evacuate the drugs that maintain vasoactive and discharge the excessive fluid that enters the body in the early stage, which requires the use of diuretics and even blood purification to discharge the excessive fluid in the body.
