Anestesiologia na era da Medicina Baseada em Evidências

Abstract

Evidence-based Medicine proposes the integration of best research evidences, physicians' clinical experience and patients' individual values. Best research evidences should be understood as relevant clinical research results, often based on basic, however patient-centered medical sciences. Their objective is to provide accuracy and precision to diagnostic tests (including physical evaluation and complementary preoperative tests) and improve both the diagnostic power of clinical indicators and the efficacy and safety of therapeutic, rehabilitation and preventive procedures. New clinical research evidences may, in certain situations, invalidate previously accepted and practiced medical attitudes (diagnostic/treatment), replacing them by others with higher efficacy and safety power.
