Adverse immune reactions and non-immune medications for perioperative use

Abstract

Reactions to medications can occur through a mechanism mediated by immunoglobulin or otherwise, not both. Drug allergy is a type of adverse reaction to the drug and comprises a range of hypersensitivity reactions mediated by different immunological mechanisms with diverse clinical manifestations. A rate of 3.2 fatal cases of anaphylaxis associated with drugs per 100,000 inhabitants per year is estimated, which seems to be approximately 10 times higher in hospitalized patients. The incidence of perioperative anaphylactic reactions is estimated at 1 in 10,000-20,000 anesthetic procedures. The diagnosis is based on a careful clinical history and physical examination. In some cases, skin tests, progressive challenges and methods to induce tolerance to the medication may be required. In hospitalized patients and at perioperative intervals, muscle relaxants, neuroleptics and morphinomimetics are frequently used and adverse reactions may occur to these drugs. This review shows a general description of the reactions of these medications, emphasizes allergic reactions and analyzes strategies for the diagnosis and treatment of these reactions.
