[Selected factors affecting long-term outcomes of in-hospital resuscitation].

BACKGROUND: Results of resuscitation attempts and subsequent survival rates can now be analysed, based on the Utstein templates. Few such reports have been published so far in Poland. METHODS: We have retrospectively analysed the outcomes of in-hospital resuscitation attempts, performed during 30 months in a large university hospital.The buildings were spread over 5.72 hectares, with the longest distance between buildings being 500 m. The resuscitation team consisted of an anaesthesiologist and a specialized nurse equipped with a basic set containing airway equipment, intravenous cannulas and drugs. Resuscitation protocols were analysed according to the Utstein templates. RESULTS: There were 198 resuscitation attempts registered. In 47% of the cases, the circulation returned, but 28% of the patients died within 24 hours. 11% were discharged home, however 9 patients died within the next 6 months. 6% of the resuscitated patients survived over 12 months and were rated grade 1 or 2 on the CPC (Cerebral Performance Category) scale.The 12-month survival rate correlated only with the time from cardiac arrest to the first adrenaline injection. The in-hospital survival rate (possibility of discharge) correlated with the duration of hospitalization before cardiac arrest, the first registered cardiac rhythm (defibrillation-susceptible), and the time to first defibrillation. DISCUSSION: The most pronounced difference between the results of in-hospital and pre-hospital CPR was the primary cardiac rhythm associated with the cardiac arrest. Defibrillation-susceptible rhythm was observed in only 15% of cases, and was associated with immediate survival and hospital discharge, but not with 12-month survival. The time to administration of the first dose of adrenaline was a sole factor associated with 12 month survival.
