Advanced training for ambulance crews: implications from 403 consecutive patients with cardiac arrest managed by crews with simple training.

Sixty seven ambulance staff in Nottinghamshire completed a simple extended training programme in managing cardiac arrest and using a defibrillator. This enabled around one third of the ambulance emergency shifts to be manned by such a crew, with a defibrillator as part of their standard equipment. Forty four of 403 consecutive patients who suffered cardiac arrest in the community were managed by these crews and survived to leave hospital. The training programme does not include endotracheal intubation, intravenous infusion, or drug administration. The new official advanced training course for ambulance crews, which includes these skills, is inappropriate in its methods and may delay widespread introduction of emergency ambulances equipped with defibrillators.     

Simple training programme for ambulance personnel in the management of cardiac arrest in the community.

The extended training for ambulance personnel in Nottinghamshire includes a period of training in cardiac resuscitation by defibrillation, and defibrillators are now part of the standard equipment of vehicles used on the accident and emergency service. Comparison of recent results with previous attempts in the City of Nottingham to provide a service for out of hospital cardiac arrest has shown that an elementary training course and the provision of defibrillators on emergency vehicles enables the ambulance service to save the lives of a reasonable proportion of those who suffer sudden death in the community. The extended training programme as a whole has proved acceptable to ambulance personnel and we believe that this programme could be the basis for a more widespread introduction of post basic training.     

The Brighton resuscitation ambulances: a continuing experiment in prehospital care by ambulance staff.

Two ambulances from the existing fleet in Brighton and one in Hove are equipped with portable defibrillator-oscilloscope units. Selected attendants have been trained not only to defibrillate patients but also to perform endotracheal intubation and administer intravenous atropine and lignocaine for carefully defined indications. In the two years up to December 1975 the ambulances responded to 2253 calls which were considered possible emergencies. Retrospective analysis showed that half of these had been for patients with myocardial infarction, coronary insufficiency, or angina. The ambulances took a median time of five minutes to reach a patient. Attempts at resuscitation were made in 207 patients with circulatory arrest, of whom 160 had ventricular fibrillation. Coordinated rhythm was restored at least transiently in 66 patients, and 27 of them survived to leave hospital. Sixteen of the survivors had been in ventricular fibrillation before the arrival of the ambulance. The delay before admission to hospital was reduced: over 50% of patients carried in the ambulances were admitted within two hours of the onset of major symptoms. No extra ambulance staff have been employed for the scheme. The increased load on hospital services has been limited by encouraging a rational admission policy and also by early discharge.     

Cardiac arrest: comparison of paramedic and conventional ambulance services.

A prospective study conducted in the Greater Vancouver area compared survival rates in prehospital cardiac arrest managed by an advanced life support (paramedic) service with those in cardiac arrest managed by conventional ambulance service. Management by the paramedic service was associated with higher survival rates for patients found in cardiac arrest but not for patients who suffered the arrest while the ambulance was present. Cardiopulmonary resuscitation by bystanders was associated with a significant increase in survival rates when combined with paramedic services but not when only basic life support services were available.
