Clinical TrialThe prognostic significance of coma-rating, duration of anoxia and cardiopulmonary resuscitation in out-of-hospital cardiac arrest.
Early determination of outcome after successful prehospital cardiopulmonary resuscitation (CPR) is a common problem with great ethical, economic, social, and legal consequences. We prospectively investigated 112 adult patients who had been resuscitated after out-of-hospital cardiac arrest (CA). The aim of our study was to determine whether coma rating by the mobile intensive care unit (MICU) is a useful tool for outcome prediction. ⋯ The first coma rating performed immediately at the time of arrival on scene had no significant prognostic value for prediction of neurological outcome (P = 0.204) and survival (P = 0.103). The second coma rating (performed after ROSC or 20-30 min after the start of CPR), however, demonstrated a significant correlation with neurological outcome (P = 0.0000) and survival (P = 0.0000), a correlation which was comparable to both duration of anoxia and duration of CPR. In patients with out-of-hospital cardiac arrest prognostic information could be obtained with the ICS as early as 20-30 min after the start of cardiopulmonary resuscitation.
