Abstract
BACKGROUND AND OBJECTIVES: Preoperative evaluation can benefit from laboratory exams in specific patients. The habit of requesting a set of standardized exams has been questioned. The objective of this review was to analyze recent reports on the subject and compare their results.
CONTENTS: The results obtained from a systematic revision of the evidence available from 1966 to 1996, from the recommendations of the task force of the American Society of Anesthesiologists, from the systematic revision of evidence from 1997 to 2002, and from the English National Health Service Orientation Guide.
CONCLUSIONS: Preoperative exams should not be based on standard routines, but on the patient's history, physical exam, and type and extent of surgery.
Resumo
JUSTIFICATIVA E OBJETIVOS: A avaliação pré-operatória pode se beneficiar da solicitação de exames complementares em determinados pacientes. A prática, comum há alguns anos, de conjuntos padronizados de exames solicitados rotineiramente tem sido questionada. O objetivo desta revisão foi analisar recentes publicações sobre o assunto comparando seus resultados.
CONTEÚDO: Foram analisados os resultados observados em revisão sistemática com as evidências disponíveis entre os anos de 1966 e 1996, em recomendações da força-tarefa da Sociedade Americana de Anestesiologistas, em atualização da revisão sistemática incluindo evidências de 1997 a 2002 e no Guia de Orientação do National Health Service da Inglaterra.
CONCLUSÕES: Os exames pré-operatórios não devem ser solicitados com base em rotinas, mas orientados pelo histórico clínico, exame físico e tipo e porte do procedimento cirúrgico.
