The literature review reflects the existing approaches to the structural organization of medical care in Russia and its provision with regulatory legal acts. A critical analysis of the list of medical services in the profile of anesthesiology and intensive care is being carried out, which requires significant adjustments and optimization. A variant of the formation and structuring of medical services as a purposeful concretized process of medical care is proposed. Various options for the development of the classification of complications of anesthesia and intensive care are presented. The paper substantiates the urgent need to form a database of various complications and adverse reactions of anesthesia and intensive care, which currently does not exist, as there are no official documents regulating and obliging to conduct this monitoring, and some documents on this issue are related exclusively to the undesirable effects of drugs.
