Shock is usually a pathological state caused by systemic acute circulatory failure from various causes.1. When shock occurs, immediately make the patient lie down and adopt the shock position, usually by elevating the lower extremities 20-30 degrees, or elevating both the head and chest as well as the lower extremities, with the head and chest elevated 20-30 degrees and the lower extremities elevated 15-20 degrees, which can increase the amount of heart return and thus reduce the burden on the heart.2. Quickly replenish blood volume, usually immediately establish 2-3 intravenous channels, and quickly replenish fluids. In case of hemorrhagic shock, blood transfusion should be requested immediately, usually with concentrated red blood cells as well as fresh frozen plasma.3. Treat the primary disease. If it is hemorrhagic shock of the extremities, the wound should be given a pressure dressing to stop bleeding, or the proximal extremity of the wound should be blocked with a tourniquet or bundle to block arterial blood flow, thus having a hemostatic effect. If the bleeding is from an organ, immediate preoperative preparation should be done to surgically stop the bleeding. If some cardiogenic problems lead to shock, should deal with the corresponding cardiac problems. 4, if after the above treatment, blood pressure still can not rise, you can apply drugs to raise blood pressure, commonly used is norepinephrine, dobutamine, alamine, etc..
