(1) Cardiac arrest: adrenaline can improve the excitability of sinoatrial node conduction system and myocardium, and can also make ventricular muscle fibrillation coarser, which is conducive to defibrillation. Epinephrine is widely used in clinic as the first choice for rescuing cardiac arrest. It is not only suitable for ventricular fibrillation, but also suitable for rescuing cardiac arrest, which is mainly due to the strong function of epinephrine α Receptor excitation, so after intravenous or intracardiac injection, during cardiac compression, it can produce higher aortic pressure, so as to improve coronary perfusion pressure, increase coronary blood flow and oxygen supply, so it is conducive to cardiopulmonary resuscitation. In addition, adrenaline also contributes to the redistribution of cerebral blood flow, which is conducive to cerebral resuscitation in patients with cardiac arrest.

(2) Anaphylactic shock: during anaphylactic shock, small blood vessels dilate, capillary permeability increases, blood pressure decreases, bronchial smooth muscle spasm and dyspnea. Adrenaline can effectively treat and quickly alleviate shock symptoms.

(3) Bronchial asthma: alleviate acute attack.

(4) Compatibility with local anesthetics and local hemostasis: the addition of adrenaline to local anesthetics can shrink the small blood vessels at the injection site, delay the absorption of local anesthetics, reduce absorption poisoning and prolong the time of local anesthesia.

(5) Treatment of urticaria, hay fever and serum reaction.
