RESUMO
The term anaphylaxis describes a severe, potentially life-threatening allergic reaction. It is caused by an acute, systemic immune response to substances against which in most cases a previous sensitization has taken place. An anaphylactic reaction can affect every organ system of the human body. The first signs of an allergic shock are symptoms such as hypotension, tachycardia, exanthema and dyspnea. The complete expression of anaphylactic shock can occur very quickly. A perioperative anaphylaxis, in particular, is not always easy to recognize. Therefore, it is important to know the possible perioperative triggers of anaphylaxis, for instance neuromuscular blocking agents and antibiotics. The treatment has to be initiated quickly to save the life of the patient. The rapid injection of epinephrine and intravenous fluid administration are most important.
