Two independent samples of 800 lay CPR trainees from an original cohort of 7584 were surveyed postally 4 years after training. Only 2% of respondents had used CPR, but 92 had used other aspects of their life support training. Those who had retrained were more confident than those who had not and 89% of those who had not retrained were willing to do so. More than 80% expressed willingness to perform full CPR on casualties who were unknown to them, but this fell to 40% where facial blood was present and 48% where the victim was a gay man.

Previous research has suggested that the physical demands of performing cardiopulmonary resuscitation (CPR) are relatively low. However, the subjects studied have generally been of a young age. The aim of this study was to test the hypothesis, in null form, that the physiological responses to the performance of single operator CPR for 10 min are independent of age. Confirmation of the hypothesis would allow the use of a period of time performing CPR as a socially non-discriminatory means of testing ability across a wide spectrum of age. ⋯ There was no significant effect of age on the physiological responses to the performance of 10 min of single operator CPR in this select group.

Comparative Study
Early fluid resuscitation improves outcomes in severely burned children.
Recent evidence suggests that timely fluid resuscitation can significantly reduce multiorgan failure and mortality in thermally injured children. In this study, children who received fluid resuscitation within 2 h of a thermal injury were compared with children in which fluid resuscitation was delayed by 2-12 h. We hypothesized that fluid resuscitation given within 2 h of a thermal injury attenuates renal failure, cardiac arrest, cardiac arrest deaths, incidence of sepsis, and overall mortality. ⋯ Data suggest that fluid resuscitation, given within 2 h of a thermal injury, may be one of the most important steps in the prevention of multi-organ failure and mortality.

Previous work by the authors has shown that chest compressions alone without mechanical ventilation during cardiopulmonary resuscitation in the natural supine position was associated with pulmonary aspiration in dogs. The purpose of this investigation was to test the hypothesis that a head down position may prevent aspiration during chest compressions alone and whether oxygenation can be improved by simply insufflation of oral oxygen 10 min after cardiac arrest. ⋯ Chest compression alone without mechanical ventilation in the supine position caused pulmonary aspiration in the unprotected airway in dogs. This complication could be prevented by adopting a 20 degree head down position. The 10 degree head down position seemed to reduce the severity of the pulmonary aspiration, but not enough to eliminate the danger altogether. Supplemental oxygen in the mouth can improve oxygenation in chest compressions alone.
