Audit of an emergency ambulance service: impact of a paramedic system.
The purpose of this survey was to assess the workload of an emergency ambulance service, to describe the use of paramedic skills by those staff with full extended training, and to predict the impact upon the provision of pre-hospital care of deploying a paramedic on every emergency ambulance. Accordingly, a week-long survey was undertaken of all urgent and emergency calls received by an ambulance service covering a mixed urban and semi-rural area of 187 square miles with a population of 396,000. Of the total 682 emergency calls 351 (51.5%) originated from the '999' system: 291 of these patients were taken to hospital where 51% were thought to have minor conditions and 141 were admitted. ⋯ One patient was resuscitated from cardiac arrest. The presence of a paramedic on every emergency ambulance increases the time spent on-scene and offers advanced pre-hospital skills to patients who need them. Care should be taken to ensure that the benefits of time spent on-scene using such skills outweigh the disadvantage of delayed hospital admission.

Neuromuscular blocking agents (NMBs) are frequently used to facilitate intubations in the hospital. The 1987 membership of the Association of Air Medical Services (AAMS) was surveyed to determine the frequency of NMB use by flight programs both before and after definitive airway control. Out of 141 programs, 101 returned completed survey forms. ⋯ The presence of a physician on the flight crew was associated with the use of succinylcholine prior to definitive airway control. Reported complications included three deaths attributed to use of NMBs in the preceding two years. We conclude that NMBs are commonly used following intubation, and that NMBs are used before intubation by some flight programs, especially those that have physician crew members.

The AHA Committee on Emergency Cardiac Care recommends that all communities strengthen the four links in the chain of survival: Early Access: Install an enhanced 911 emergency dispatch system. Provide certification training to all emergency medical dispatchers. Develop community-wide education and publicity programs that focus on cardiac emergencies and a proper response by citizens. ⋯ Implement more widespread use of automated external defibrillators by community responders and allied health responders. Early Advanced Life Support: Coordinate advanced life support units with first-response units that provide early defibrillation. Develop procedures that combine rapid defibrillation by first-response units with rapid intubation and intravenous medications by the advanced life support units.

The optimal dose of epinephrine in human cardiac arrest remains an area of continuing controversy. Apart from animal data some anecdotal reports in humans suggest that the dose currently recommended by the AHA may be insufficient for resuscitation of spontaneous circulation during prolonged cardiac arrest (CA). Since 1982, 1610 CA patients registered in Bruges have been evaluated under the following variables: prolonged survival (class 3 CPCR successes); solely restoration of spontaneous circulation (ROSC): class 2a, 2b and 3); epinephrine dose used during cardiopulmonary resuscitation (CPR); duration of advanced life support (ALS) and duration of complete CA. ⋯ E. M.) for the total population (n = 1724) was 2.53 +/- 0.06 mg; for patients since March 1989 (n = 114) this number was 5.58 +/- 0.36 mg. In contrast to the period before March 1989, we found a non-significant positive correlation between the survival of class 3 and epinephrine dose by limiting the influence of CPR times in the asystole and electromechanical dissociation (EMD) arrest groups.
