Randomized Controlled Trial Multicenter Study
The effect of time on CPR and automated external defibrillator skills in the Public Access Defibrillation Trial.
The time to skill deterioration between primary training/retraining and further retraining in cardiopulmonary resuscitation (CPR) and automated external defibrillation (AED) for lay-persons is unclear. The Public Access Defibrillation (PAD) trial was a multi-center randomized controlled trial evaluating survival after CPR-only versus CPR+AED delivered by onsite non-medical volunteer responders in out-of-hospital cardiac arrest. ⋯ After primary training/retraining, the CPR skills of targeted lay responders deteriorate nominally but 80% remain competent up to 1 year. AED skills do not deteriorate significantly and 90% of volunteers remain competent up to 1 year.

Review Meta Analysis
Should a benzodiazepine antagonist be used in unconscious patients presenting to the emergency department?
Patients in coma with suspected drug poisoning are commonly encountered in the emergency department. Benzodiazepines are one of the most commonly used drugs in self-poisoning. Flumazenil, a benzodiazepine antagonist has been suggested as a diagnostic and treatment tool in suspected poisoning of unclear cause, but caution is required due to potential side effects. No systemic review of this literature has been done on this topic. ⋯ Current evidence shows that flumazenil may be effective in the reversal of coma in patients presenting to the emergency department with coma from suspected drug poisoning.

Randomized Controlled Trial Comparative Study
Medical students teaching basic life support to school children as a required element of medical education: a randomised controlled study comparing three different approaches to fifth year medical training in emergency medicine.
Basic life support (BLS) by doctors has been shown to be of poor quality. To improve medical education training should be simplified, and simultaneously the learner should be involved more actively. To combine both ideas we trained medical students to give BLS courses and sent them to teach school children. This was a requirement for their emergency medicine course. Our model was compared to conventional teaching. ⋯ Medical students teaching BLS to school children as a compulsory element of their own medical training showed superior practical skills as compared to conventional teaching. Theoretical knowledge was equivalent to the control groups, although their course contained less theoretical information.

This study evaluates inter-rater reliability and comfort of BLS providers with the application of an out-of-hospital Basic Life Support Termination of Resuscitation (BLS TOR) clinical prediction rule. This rule suggests that continued BLS cardiac resuscitation is futile and can be terminated in the field if the following three conditions are met: (1) no return of spontaneous circulation; (2) no shock given prior to transport; (3) cardiac arrest not witnessed by EMS personnel. ⋯ The vast majority of providers were able to apply the BLS TOR clinical prediction rule correctly and were comfortable doing so. This suggests that both reliability and comfort will remain high during routine application of the rule when paramedics are well trained as users of the rule.
