Effects of activated protein C on post cardiac arrest microcirculation: an in vivo microscopy study.
The clinical symptoms and pathophysiologic mechanisms during and after ischaemia-reperfusion following cardiac arrest (CA) and successful cardiopulmonary resuscitation (CPR) closely resemble those observed in patients with severe sepsis. Impairment of microcirculation and endothelial leakage seem to play key roles in the underlying pathophysiology. Recombinant human activated protein C (rhAPC) is the first drug being licensed for the treatment of severe sepsis in patients. Therefore, for the first time, we investigated effects of rhAPC on microhaemodynamic changes and endothelial leakage applying in vivo microscopy of postcapillary mesenteric venules after CA and CPR in rats. ⋯ Our results show that CA with consecutive successful CPR leads to a microcirculatory impairment closely resembling experimentally induced sepsis. Intriguingly, despite these similarities, rhAPC had no significant effects on WSR and PE. Our results strongly suggest that further mechanisms such as mast cell activation might play an important role and have therefore to be studied to elucidate the pathophysiology of "postresuscitation disease".

Multicenter Study Comparative Study
Serum S-100B is superior to neuron-specific enolase as an early prognostic biomarker for neurological outcome following cardiopulmonary resuscitation.
Most patients with cardiac arrest (CA) admitted to hospitals after successful cardiopulmonary resuscitation (CPR) are discharged with various degree of neurological deficits. To determine predictor of neurological outcome early and accurately, and to determine cutoff values, serum levels of protein S-100B and neuron-specific enolase (NSE) within 24h after CA were assessed. ⋯ S-100B is more reliable as an early predictor of poor neurological outcome within 24h after CA than NSE and can be applied clinically.

Characteristics of out-of-hospital paediatric emergencies attended by ambulance- and helicopter-based emergency physicians.
In Germany, as in many other countries, for the vast majority of cases, critical out-of-hospital (OOH) paediatric emergencies are attended by non-specialised emergency physicians (EPs). As it is assumed that this may lead to deficient service we aimed to gather robust data on the characteristics of OOH paediatric emergencies. ⋯ Our data suggest that EPs need to be particularly confident with the care of children suffering respiratory disorders, convulsions, and trauma. The incidence of severe paediatric OOH emergencies requiring advanced interventions is higher in HEMS-attended cases. However, well-developed skills in airway management, CPR, and intraosseous canulation in children are essential for all EPs.
