We describe the design of a universal report form for use by lay-responders using an automated external defibrillator (AED) as part of a national programme for public access defibrillation (PAD). The form was designed initially because the Department of Health in England required detailed audit data about the national programme for public access defibrillation they initiated. ⋯ The form evolved pragmatically as experience showed the wide range of situations under which lay-persons might use an AED, and also the information likely to be available that could be collected reliably. This report may help others who wish to audit schemes for PAD and facilitate the evolution of an internationally acceptable template for data collection.

Standard cardiopulmonary resuscitation (CPR) may be difficult to perform in a confined space. This study set out to evaluate alternative techniques of chest compression, which may be easier to perform in such situations. Nineteen airline employees, trained in basic life support (BLS), were recruited to take part in the study. ⋯ It was concluded that the quality of chest compression during two-person straddle CPR compares favorably with chest compression during standard two-person CPR, and may be useful in situations where space is limited. If only one rescuer is available to perform CPR, and limited space makes it impossible to carry out standard CPR, over-the-head CPR is an alternative method. However, in this study, hand placement during chest compression was poor, and additional training may be necessary before it can be considered a safe technique.

The severity of airway obstruction varies in infants with Pierre-Robin syndrome (PRS). Some have severe upper airway obstruction that results in respiratory failure and even death. We report a case of neonate with isolated PRS who had a severe airway obstruction and respiratory failure after birth. ⋯ The laryngeal mask airway was left inserted for 6 days. It was successful in this patient and eliminated the need for invasive surgical procedures. In conclusion, the relatively long term use of a laryngeal mask airway, which has not been reported before, could be an alternative therapy for patients with PRS with airway obstruction.

Randomized Controlled Trial Multicenter Study Clinical Trial
Conducting research using the emergency exception from informed consent: the Public Access Defibrillation (PAD) Trial experience.
The Public Access Defibrillation (PAD) Trial, a prospective, multicenter, randomized clinical trial comparing two prehospital resuscitation strategies, was conducted under the regulations for exception from informed consent (21CFR50.24) in 24 communities in North America. These regulations place additional requirements for human subject protection on investigators and Institutional Review Boards (IRBs), including conducting community consultation (CC) and public disclosure (PD). ⋯ The length of time to obtain IRB approval and the extent of community consultation and public disclosure varied greatly among trial sites in meeting the current regulations for conducting emergency research with exception from informed consent. This suggests that more specific guidance may be useful and that determination of effective strategies for community consultation and public disclosure is needed.

Randomized Controlled Trial Comparative Study Clinical Trial
Trials of teaching methods in basic life support (4): comparison of simulated CPR performance at unannounced home testing after conventional or staged training.
This study compares the retention of basic life support (BLS) skills after 6 and 12 months by lay persons trained either in a conventional manner, or using a staged approach. Three classes, each of 2h, were offered to volunteers over a period of 4 months. For the conventional group, the second and third classes consisted of review of skills. ⋯ At 12 months, those taught by the staged method were significantly better at shouting for help (P = 0.005), time to first compression (P < 0.0001), and compression depth (P = 0.003). Those taught conventionally were significantly better at checking for a carotid pulse at both 6 and 12 months (P < 0.0001). These results suggest that training lay persons in basic life support skills using a staged approach leads to overall better skill retention at 6 and 12 months, and has other advantages including a greater willingness to re-attend follow-up classes.
