Cardiogenic shock, the situation is more critical, the first choice of drugs need to be selected according to the different conditions of the patient, if the patient has a cardiac arrest should be preferred epinephrine; if the right heart failure caused by shock, saline, dextrose anhydride, etc.; if the left heart failure caused by shock, dopa-phenobutylamine, furosemide, etc., should be applied under the direction of the doctor. 1. Cardiac arrest: cardiac arrest is the most critical situation of cardiogenic shock, the patient’s condition needs to be determined immediately, and cardiopulmonary resuscitation treatment, at this time the first choice of drugs for the epinephrine, which can be stronger stimulation of the heart, so that it restores the ejection function. 2. Right heart failure: if shock occurs because of right heart failure, such as right ventricular infarction, etc., the reason for shock is that the preload of the heart is impaired, and a large amount of blood stagnation in the venous system, at this time, we need to drip saline or dextrose anhydride and other volume expansion, to elevate preload and restore perfusion. 3. Left heart failure: if shock occurs because of left heart failure, such as anterior wall, high lateral wall myocardial infarction, etc., at this time the need to apply dopamine, excitation of cardiac β1 receptor, can enhance myocardial contractility, increase cardiac output, at the same time the need for furosemide and other medications diuretic, reduce the cardiac load, relieve shock. In the event of cardiogenic shock, you should immediately call 120 emergency center, get in touch with your doctor as early as possible, and carry out the initial treatment measures under the doctor’s guidance, do not blindly use drugs to avoid irreversible damage.
