To determine the efficacy of atropine therapy in patients with hemodynamically compromising bradycardia or atrioventricular block (AVB) in the prehospital and emergency department settings. ⋯ Approximately one-half of patients who received atropine in the prehospital setting for compromising rhythms had either a partial or complete response to therapy. Adverse responses were uncommon. Those patients who presented with hemodynamically unstable bradycardia to EMS personnel responded more commonly to a single dose and a lower total dose of atropine compared to similar patients with AVB. Those patients who achieve normal sinus rhythm by ED discharge were likely to have achieved it during the prehospital interval.

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.

This paper describes a novel method for delivering basic life support training to undergraduate healthcare students. A comprehensive 8 h programme is organised and delivered by undergraduate students to their peers. ⋯ It has been well received by students and academic staff and provides a solution to reduce the workload of over burdened clinical staff while at the same time enhancing quality. It forms part of an overall strategy for improving resuscitation training for undergraduates from all disciplines.

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.

Randomized Controlled Trial Clinical Trial
Aminophylline in undifferentiated out-of-hospital asystolic cardiac arrest.
To determine if the introduction of intravenous aminophylline, a nonspecific adenosine receptor antagonist, into the resuscitation algorithm of asystole will increase return of spontaneous circulation when used in undifferentiated prehospital cardiac arrest. ⋯ We were not able to show a statistically significant improvement in return of spontaneous circulation when aminophylline was given during the early resuscitation phase of undifferentiated asystolic cardiac arrest in the prehospital setting with this sample size.
