Kvaliteten på avansert hjerte- og lungeredning under simuleringstrening

Abstract

Background: The survival rate after cardiac arrest decreases by 10-15 % for each minute without cardiopulmonary resuscitation (CPR). Early introduction of CPR and good quality of performance are important predictors of survival. Objectives:The objective of this project was to measure the quality of advanced CPR during simulation training, and to see if the results are in accordance with the Norwegian guidelines of 2005. Methods:Prospective observational study during full-scale simulation training. Data were collected from a computer connected to a manikin, in addition to video recordings 48 nurses and 16 physicians working at an intensive coronary care unit (ICCU) participated.Results: Mean frequency of chest compressions was 104, with a mean depth of 48 mm. Time from occurrence of ventricular fibrillation to delivered countershock was median 82 seconds and median 25 seconds when the defibrillator was located outside or inside the room, respectively. The total hands-off time was 25 %. Mostly, medications were given correctly (92 %) with a high degree of double control (94 %). Chest compression was continued during charging of the defibrillator in 86 % of the charging intervals. In 17 % of the episodes, countershocks were delivered without following the safety precautions. When consecutive countershocks could have been given according to guidelines, it was performed in half of the cases (54 %). Conclusion:The quality of performed advanced CPR is in accordance with the Norwegian guidelines of 2005. The algorithm was followed correctly in almost every scenario, and the technical performance was good. Current results indicate no unnecessary hands-off time.
