Prehospital blood gas analysis is a new method in out-of-hospital emergency care. In a prospective pilot study we evaluated the feasibility of prehospital compensation of severe acidosis relying on different monitoring systems to evaluate patients oxygen, carbon dioxide or acid-base status, respectively. ⋯ Arterial blood gas analysis proved to be helpful in the optimal management of out of hospital cardiac arrest. The incidence of severe acidosis in patients undergoing cardiopulmonary resuscitation was 80%. The probability of developing acidosis was found to increase slightly depending on the time elapsed since the beginning of CPR. The application of a calculated buffering of acidosis with sodium bicarbonate showed a good outcome in selected cases. In emergency patients alternative methods fail to detect severe disturbances of the patients oxygen and/or carbon dioxide status and the acid-base balance. Management of prehospital cardiac arrest could be optimized by the routine use of blood gas analysis.

Early defibrillation is the standard of care for patients with ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT). Technical developments aim at further miniaturization and simplification of defibrillators as well as adaptation of energy requirements to the patient's needs. Implantable Cardioverter-Defibrillators (ICD) and automated external defibrillators (AED) are based upon the same technology. ⋯ Developments concerning the structure of in-hospital emergency systems or pre-hospital emergency medical services (EMS) aim at further reductions in time from collapse of a patient until first defibrillation. Such developments include early defibrillation programs for emergency medical technicians (EMT), nurses, and fire or police department first responders as well as wide distribution of easy-to-operate defibrillators in public areas, as discussed during the American Heart Association's Public Access Defibrillation conferences. All programs of that kind have to be organized and supervised by a physician who is responsible for training and supervision of the personnel involved.

Randomized Controlled Trial Comparative Study Clinical Trial
[Can sevoflurane save time in routine clincal use? A comparison with halothane in pediatric anesthesia].
The volatile agent sevoflurane enables a rapid emergence from anaesthesia. The aim of this study was to investigate the possibility of increasing turnover in pediatric anaesthetic cases by use of sevoflurane in comparison with halothane. Often short cases or day cases need rapid turnover. ⋯ Sevoflurane offers the potential for shortening turnover in pediatric anaesthesia.
