چکیده

Justificativa e Objetivos O controle da dor pós-operatória tem sido muito investigado nas últimas décadas, quando se verificou que a analgesia pós-operatória era inadequada. O termo “preemptiva” implica em uma forma de analgesia que, iniciada antes do estímulo doloroso ser gerado, previne ou diminui a dor subseqüente. Este estudo tem como objetivo uma atualização sobre analgesia preemptiva possibilitando novas alternativas para o tratamento da dor pós-operatória. Conteúdo A analgesia preemptiva foi recomendada para prevenir a dor causada por mudanças no sistema nervoso central durante o ato operatório, devido à não supressão da condução do estímulo doloroso para o encéfalo. Vários estudos tanto laboratoriais como clínicos têm sido realizados com o intuito de demonstrar efeito preemptivo de métodos de analgesia, porém os resultados ainda são discutíveis e conflitantes. Conclusões Apesar de existir algumas evidências clínicas do efeito da analgesia preemptiva, há necessidade de mais estudos para elucidar o real valor desse tipo de analgesia no controle da dor pós-operatória.
