RESUMEN
The European guidelines on cardiopulmonary resuscitation, which are divided into 12 chapters, have recently been published. In addition to the already known chapters, the topics "epidemiology" and "life-saving systems" have been integrated for the first time. For each chapter five practical key statements were formulated. In the present article the revised recommendations on basic measures and advanced resuscitation measures in adults as well as on postresuscitation treatment are summarized and commented on.

INTRODUCTION: Predicting the neurological outcome after cardiopulmonary resuscitation (CPR) is extremely difficult. We tested the hypothesis whether monitoring of bispectral index (BIS) and suppression ratio (SR) could serve as an early prognostic indicator of neurological outcomes after CPR. METHODS: Cerebral monitoring (BIS, SR) was started as soon as possible after initiation of CPR and was continued for up to 72h. The functional neurological outcome was measured on day 3, day 7 and again one month after CPR via a clinical examination and assessment according to the cerebral performance category score (CPC). RESULTS: In total 79 patients were included. Of these, 26 patients (32.9%) survived the observation period of one month; 7 of them (8.9%) showed an unfavourable neurological outcome. These 7 patients had significantly lower median BIS values (25 [21;37] vs. 61 [51;70]) and higher SR (56 [44;64] vs. 7 [1;22]) during the first 4h after the initiation of CPR. Using BIS<40 as threshold criteria, unfavourable neurological outcome was predicted with a specificity of 89.5% and a sensitivity of 85.7%. The odds ratio for predicting an unfavourable neurological outcome was 0.921 (95% CI 0.853-0.985). The likelihood to remain in a poor neurological condition decreased by 7.9% for each additional point of BIS, on average. CONCLUSION: Our results suggest that BIS and SR are helpful tools in the evaluation of the neurological outcomes of resuscitated patients. Nevertheless, therapeutic decisions have to be confirmed through further examinations due to the far-ranging consequences of false positive results.

Patients with acute ST-segment elevation myocardial infarction (STEMI) needing prehospital cardiopulmonary resuscitation (CPR) have a very high adverse-event rate. However, little is known about the fate of these patients and predictors of mortality in the era of early reperfusion therapy. From March 2003 through December 2004, 2,317 patients with prehospital diagnosed STEMI were enrolled in the Prehospital Myocardial Infarction Registry. One hundred ninety patients (8.2%) underwent prehospital CPR and were included in our analysis. Overall 90% of patients were treated with early reperfusion therapy, 56.3% received prehospital thrombolysis and 1/2 of these patients received early percutaneous coronary intervention after thrombolysis, 28.4% of patients were treated with primary percutaneous coronary intervention, and 5.3% received in-hospital thrombolysis. Total mortality was 40.0%. The highest mortality was seen in patients with asystole (63%) or pulseless electric activity (64%). Independent predictors of mortality were need for endotracheal intubation and older age, whereas ventricular fibrillation as initial heart rhythm was associated with survival. In conclusion, in this large registry with prehospital diagnosed STEMI, incidence of prehospital CPR was about 8%. Even with a very high rate of early reperfusion therapy, in-hospital mortality was high. Especially in elderly patients with asystole as initial heart rhythm and with need for endotracheal intubation, prognosis is poor despite aggressive reperfusion therapy.

BACKGROUND: In 2004, the German federal state of Baden-Württemberg implemented a quality management system for pre-hospital emergency care. Since then, there has been a semi-annual assessment of the frequency of different types of emergency medical interventions and the quality of care. METHODS: The frequencies of different types of intervention were determined and reported both in absolute numbers and as incidence figures, i.e., interventions per 1000 inhabitants per year. The quality of care was rated with the Mainz Emergency Evaluation Score (MEES), and analyses of resuscitation outcomes and guideline implementation were performed. RESULTS: From 2004 to 2008, there were a total of 524,833 pre-hospital emergency medical interventions in Baden-Württemberg. The annual incidence of emergency interventions rose by 22% over this period (from 16.2 to 19.9 interventions per 1000 inhabitants per year), and the percentage of patients who were severely ill or severely injured rose as well, from 47.3% to 51.1%. The percentage of patients over age 75 rose from 29.1% to 31.3%. 11,858 patients with myocardial infarction (MI) were treated in 2008; the incidence of treatment for MI rose by 60% from 2004 to 2008, from 0.907 to 1.448 interventions per 1000 inhabitants per year. A major improvement in the diagnostic evaluation of MI came about through the purchase of more 12-channel ECG machines. In 2008, the emergency medical teams succeeded in improving the patient's condition in 69.07% of all cases (77.9% for MI, 63.2% for stroke, 74.4% for multiple trauma). 21 patients per 100,000 inhabitants per year arrived in the hospital alive after out-of-hospital cardiac arrest and pre-hospital resuscitation. CONCLUSIONS: Even in the face of increasing utilization, the quality of emergency medical care in Baden-Württemberg has remained high. Since a quality management system was introduced in 2004, the physicians in charge of emergency medical teams have had access to the data that they need in order to evaluate and further develop the services that they provide.
