Care of patient resuscitated from cardiac arrest.

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.
