Abstract 20: Bystander Basic Life Support and the European Resuscitation Council Guidelines 2005
Background International Basic Life Support (BLS) algorithms have been designed, validated and published to meliorate the outcome in the case of cardiac arrest. The European Resuscitation Council (ERC) Guidelines 2005 have brought major changes in the adult BLS algorithm. The aim of our investigation was to detect possible advantages through the simplifications made.
Methods As indicators we chose guideline adherence during training and time to the start of chest compressions. Therefore, we evaluated in an unblinded cross-over design, how well a random sample of people could adhere to the BLS steps according to the ERC Guidelines 2000 (A) and 2005 (B), as well as the time needed until the onset of chest compressions. Volunteers were recruited in a Center for Blood Donation of the Austrian Red Cross. After electronic randomisation in commencing with Group A or B, the volutneers were taught a BLS sequence and given possibility to train until they felt confident before evaluation. Recording was performed automatically with a recording resuscitation manikin.
Results 60 people were included in the study, one individual dropped out after randomisation. 15% of group A repeated the BLS steps completely, versus 41% in group B. The interval until the onset of the chest compressions differed significantly (p<0,01). 36,7s ± 11,8sec. SD group A versus 21,3s ± 7,1 sec. SD group B.
Discussion Our results indicate that people can adhere to the BLS steps according to the ERC Guidelines 2005 more easliy than according to the old guidelines. Significant reduction of the time needed until the onset of the chest compressions can hopefully be translated in better survival after cardiac arrest.
