The outcome among patients who are hospitalised alive after out-of-hospital cardiac arrest is still relatively poor. At present, there are no clear guidelines specifying how they should be treated. The aim of this survey was to describe the outcome for initial survivors of out-of-hospital cardiac arrest when a more aggressive approach was applied. ⋯ In an era in which a more aggressive attitude was applied in post-resuscitation care, we found that the survival (32%) was similar to that in previous surveys. However, early coronary angiography was associated with a marked increase in survival and might be of benefit to many of these patients. Larger registries are important to further confirm the value of hypothermia in representative patient populations.

The incidence of human errors in the field of medicine is high. Two strategies to increase patient safety are simulator training and crew resource management (CRM) seminars, psychological courses on human performance and error management. ⋯ We established the first course curriculum combining psychological teaching with simulator training for healthcare professionals in emergency medicine. Similar concepts using the six-step approach can be applied to other medical specialties.

Cold infusions have proved to be effective for induction of therapeutic hypothermia after cardiac arrest but so far have not been used for hypothermia maintenance. This study investigates if hypothermia can be induced and maintained by repetitive infusions of cold fluids and muscle relaxants. ⋯ Cold infusions are effective for induction of hypothermia after cardiac arrest, but for maintenance additional cooling techniques are necessary in most cases.

Bradycardia may represent a serious emergency. The need for temporary and permanent pacing is unknown. ⋯ In our cohort, about 20% of the patients presenting with compromising bradycardia required temporary emergency pacing for initial stabilisation, in 50% permanent pacing had to be established.

In cardiopulmonary resuscitation, different ratios of compression to ventilation with regard to optimal oxygen transport are considered. We hypothesised that the end tidal fraction of oxygen might increase from levels found in the conventional compression-ventilation ratio of 15:2 if more consecutive ventilations are given because the rescuer would hyperventilate. The second hypothesis was that the air blown into an infant with mouth to mouth ventilation consists of rescuer's dead space air only, meaning that the fraction of oxygen should increase. ⋯ Increasing consecutive compressions and ventilations above 15:2 leads to a statistically significant increase in expired fraction of oxygen. In infant ventilation, the air exhaled into a victim contains some dead space air with a higher end tidal oxygen fraction than in adults.
