Abstract
JUSTIFICATIVA E OBJETIVOS: A parada cardiorrespiratória (PCR) ocorrida em ambulatório tem elevada mortalidade, sendo a sobrevida entre 5% e 35%. Dos pacientes que são reanimados uma percentagem elevada permanece com déficits neurológicos, resultantes das lesões ocorridas, tanto no período de ausência de circulação ou durante a reperfusão. No entanto a compreensão dos mecanismos da lesão cerebral não tem traduzido na melhoria do prognóstico. A hipotermia terapêutica após a reanimação parece ser uma opção válida associada à diminuição destas seqüelas neurológicas. O objetivo deste estudo foi rever a evidência científica relativa à abordagem do paciente reanimado após PCR. CONTEÚDO: Descrição e abordagem dos principais fatores de risco associados à lesão neurológica após PCR, bem como dos seus critérios de prognóstico.Feita pesquisa não sistemática na base de dados PubMed dos artigos referentes à abordagem terapêutica dos pacientes reanimados de parada cardíaca. As referências bibliográficas dos artigos de revisão foram igualmente analisadas. Elaboradas normas práticas para essa abordagem. CONCLUSÕES: Os pacientes que sobrevivem à PCR têm elevado risco de permanecer com lesões neurológicas graves. A hipotermia terapêutica e o controle das variáveis fisiológicas, com otimização da perfusão cerebral, podem melhorar o seu prognóstico.
BACKGROUND AND OBJECTIVES: Out-of-hospital cardiac arrest is a major cause of death with survival rates as low as 5% to 35%. A large number of patients who survive resuscitation will face significant neurological damage, as a result of the ischemia that occurs both during cardiac arrest and reperfusion. However understanding of the mechanisms responsible for brain damage has not resulted in prognostic improvement. Therapeutic hypothermia after resuscitation may be a valid option associated to reduction of neurological damage. The purpose of this study was to review scientific evidence related to a therapy for patients resuscitated from cardiac arrest. CONTENTS: Description and analysis of the main risk factors associated with neurological damage after resuscitation from cardiac arrest as well as prognostic criteria was carried out. A non-systematic search was conducted in the PubMed data base for papers on a therapeutic approach for patients resuscitated from cardiac arrest. Bibliographic references of reviewed papers were also analyzed. Practical rules were drafted for such an approach. CONCLUSIONS: Patients resuscitated from cardiac arrest face a high level of risk of neurological damage. Therapeutic hypothermia and control of physiological parameters to optimise brain perfusion, may improve prognosis.
