Atropine Coma
摘要
Insulin coma and various types of convulsive therapies were the major biologic treatment modalities in psychiatry before the psychopharmacological era. Except for electroconvulsive therapy (ECT), these methods disappeared from the psychiatric armamentarium after the introduction of psychotropic drugs. Atropine coma therapy (ACT) was one variety of nonconvulsive coma therapy used from the 1950s in a few state mental hospitals in the United States and in several Middle- and Eastern European countries until the late 1970s. In ACT, a coma of 6-10 hours' duration was induced with doses of parenteral atropine sulfate that were hundreds of times greater than the therapeutic dose administered in internal medicine. Although ACT was given to thousands of patients with a variety of diagnoses for nearly 3 decades, it is rarely mentioned, even in papers on the history of psychiatry. The method, indications, contraindications and adverse effects of ACT are summarized together with patients' personal accounts. Hypotheses concerning its mode of action are briefly mentioned. The reasons why ACT never gained wider acceptance are explored in the context of both contemporary psychiatric practice and the broader sociocultural climate of the era.
