Randomized Controlled Trial Clinical Trial
Increased frequency of thorax injuries with ACD-CPR.
A prospective, randomised out-of-hospital study in a two-tiered system with active compression-decompression (ACD) cardiopulmonary resuscitation (CPR) versus standard (STD) CPR in patients following non-traumatic cardiac arrest was planned to test the hypothesis that ACD-CPR by the first tier may increase the occurrence of ventricular fibrillation as compared with STD-CPR. Furthermore, in a later phase of the study, sternal and rib fractures induced by both CPR methods were determined by extensive autopsy. After enrolling 90 patients the study was terminated because of a high frequency of chest injuries found at autopsy. ⋯ In order to obtain a sufficiently large control group for autopsy findings after STD-CPR, STD-CPR was performed in an additional 33 patients within a second period of 4 months. There was no improvement in the number of patients found in ventricular fibrillation after ACD-CPR as compared to STD-CPR performed by the first tier. In patients undergoing autopsy (n = 35) there were significantly more sternal fractures with ACD-CPR versus STD-CPR (14/15 vs. 6/20; P <0.005) and rib fractures (13/15 vs. 11/20; P < 0.05) In conclusion, ACD-CPR appears to cause more CPR-related injuries than does standard CPR, but as a result of a number of limitations on this study, this fact cannot be proven beyond doubt.

Since the introduction around 1960 of external cardiopulmonary resuscitation (CPR) basic life support (BLS) without equipment, i.e. steps A (airway control)-B (mouth-to-mouth breathing)-C (chest (cardiac) compressions), training courses by instructors have been provided, first to medical personnel and later to some but not all lay persons. At present, fewer than 30% of out-of-hospital resuscitation attempts are initiated by lay bystanders. The numbers of lives saved have remained suboptimal, in part because of a weak or absent first link in the life support chain. ⋯ LSFA should be part of basic health education. LSFA self-learning laboratories should be set up and maintained in schools and drivers' license stations. The trauma-focused steps of LSFA are important for 'buddy help' in military combat casualty care, and natural mass disasters.
