The new German resuscitation guidelines in the context of international recommendations

Abstract

The German Guidelines for Cardiopulmonary Resuscitation were adapted to match the revised International Guidelines. The revised German edition was based both on the guidelines issued by the American Heart Association (AHA) in 1992 and on those of the European Resuscitation Council (ERC) of 1998, as well as on those released by the International Liaison Committee on Resuscitation (ILCOR) in 1997. Due to the diverging instructions for action the emergency physicians felt considerably unsafe as to what they should really do to achieve maximum results. Only 10.3 per cent of the german emergency physicians followed the recommendations given by the German Federal Chamber of Physicians. Innovations in respect of the basic checkup concern the time for controlling the respiration and circulation (ten seconds). Contrary to the international recommendations the "diagnostic block" is performed in Germany without interspersing basic reanimation. In artificial respiration the tidal volume has been reduced to 600 ml in accordance to the ERC and ILCOR guidelines. The search for the pressure point for cardiac pressure massage has also been adapted to the international recommendations. Also in accordance with the international recommendations defibrillation in case of ventricular fibrillation is now being performed only thrice in series without interspersed basic reanimation. There is some uncertainty with regard to choosing the requisite energy: 16.6% of the emergency physicians opt for less than 200 joule in primary defibrillation whereas 13% are in favour of more than 200 joule. Contrary to the international recommendations which prescribe peripheral venous access as application site for reanimation by drugs, the german guidelines favour the endobronchial path, which is already being practised by 57.4% of the emergency physicians. Hence, emergency medication can be effected in Germany 4 minutes earlier than in other countries. After three unsuccessful applications of 1 mg each of adrenalin the dosage is increased to 5 mg, and in agreement with the AHA guidelines escalating doses are also possible. Sodium bicarbonate is recommended only after more than 20 minutes of reanimation and if so, only in a reduced dose of 0.5 mval/kg body weight. In accordance with the international recommendations there is now a universal algorithm that decides on application only between ventricular fibrillation and nonfibrillation. The new german recommendations have adapted the reanimation procedure in agreement with ERC to national usage without abandoning any principles of the international guidelines.
