Summary
Early defibrillation by emergency medical technicians (EMTs) using automated external defibrillators (AEDs) is feasible and improves cardiac arrest survival rates. However, delays in emergency medical service access and advanced care limit long-term outcomes.
Area of Science:
- Emergency Medicine
- Cardiology
- Public Health
Background:
- First-aid ambulance teams in Brussels arrive 10 minutes before physician-manned ambulances for cardiac arrest patients.
- This time disparity creates an opportunity for early intervention by non-physician personnel.
Purpose of the Study:
- To assess the feasibility of early defibrillation by emergency medical technicians (EMTs) using automated external defibrillators (AEDs).
- To evaluate the impact of EMT-led early defibrillation on cardiac arrest survival rates in Brussels.
Main Methods:
- 300 EMTs underwent a 20-hour AED training course with regular refresher sessions.
- A study included 316 cardiac arrest cases, analyzing rhythm on EMT arrival and timing of defibrillation.
- Survival rates were compared before and after the AED program implementation.
Main Results:
- Ventricular fibrillation/ventricular tachycardia (VF/VT) was present in 33% of cases upon EMT arrival.
- EMTs performed defibrillation 7-9 minutes before physician arrival in VF/VT cases.
- Overall cardiac arrest survival improved from 7% (1989) to 19% (1992).
Conclusions:
- Early defibrillation by EMTs using AEDs is feasible with proper training and follow-up.
- Delays in emergency medical service (EMS) access and advanced cardiac life support (ACLS) are critical limitations.
- AED programs enhance EMT and medical team engagement and effectiveness in cardiac arrest management.
