Cost minimisation study of transdermal glyceryl trinitrate in reducing failures of peripheral intravenous infusion.

We confirm the importance of short response times, and they should be reduced further when more staff are available.About half of the patients received some resuscitation from bystanders despite a shortage of formal training of the public.Without the availability of rapid defibrillation resuscitation by bystanders will be only of limited value.The introduction of semiautomatic, advisory defibrillators for non-extended trained crews should reduce the time to defibrillation and make this procedure available to more people.5This combination of extended and non-extended trained crews may prove most effective.This study was made possible by the work of many members of the ambulance service and the extended training advisory group.
