Ventricular fibrillation occurs in 10-20% of pediatric cardiac arrests. Survival rates in children with ventricular fibrillation can be as high as 30% when the rhythm is identified and treated promptly. In the last 5 years, recommendations have been made for the use of automated external defibrillators in children between 1 and 8 years of age. ⋯ At the present time, publication of new or interim guidelines in the scientific literature alone is insufficient to ensure that new protocols are implemented. An effective and efficient method to disseminate new pediatric out-of-hospital protocols emergency care to become standard of care in a timely matter must be developed.

The study was conducted to investigate the retention of CPR and AED skills, first aid knowledge and perceived levels of confidence for a sample of 35 cabin crew 12 months after recurrent training. The 35 cabin crew undertook a mock resuscitation scenario using the AED and bag-valve-mask carried in the medical kit. ⋯ The results of this study indicate that cabin crew may not have sufficiently high levels of skill to manage a cardiac arrest adequately. This suggests that existing approaches to training of cabin crew require further investigation and modification.

The impact of the ILCOR 2005 CPR guidelines on a physical fitness assessment: a comparison of old and new protocols.
St. John Ambulance Australia has used the performance of CPR for 10 min as a fitness test for its members. Recent changes in international guidelines for cardiopulmonary resuscitation caused concern that the new ILCOR protocol was more strenuous than the previous one. This study compared the two protocols to determine if there were significant differences and to allow an evidence-based decision on the continuation or modification of this practice. ⋯ The new protocol increases both objective and subjective measures of effort. While the absolute differences in workload are small, they are statistically significant. There are significant indicators of this difference in the first 3 min of assessment. Rescuers are more likely to be operating at a high-level of physical activity. To avoid increasing the demands of its mandatory fitness test, St. John should reduce the required performance time from its present 10 min.

While airway and ventilatory compromise are significant concerns following traumatic brain injury (TBI), there is little data supporting an aggressive approach to airway management by prehospital personnel, and a growing number of reports suggesting an association between early intubation and increased mortality. Recent clinical and experimental data suggest that hyperventilation is an important contributor to these adverse outcomes in TBI patients. ⋯ In addition, experimental data regarding potential mechanisms for the adverse effects of hyperventilation and hypocapnia on the injured brain are presented. Finally, the limited data regarding the impact of hypoventilation and hypercapnia on outcome from TBI are discussed.
