Refibrillation managed by EMT-Ds: incidence and outcome without paramedic back-up

Area of Science:

• Emergency medicine
• Cardiology
• Pre-hospital care

Background:

• Ventricular fibrillation (VF) is a life-threatening arrhythmia.
• Defibrillation-trained emergency medical technicians (EMT-Ds) can convert VF to organized rhythms.
• Some patients refibrillate before reaching the hospital.

Purpose of the Study:

• To analyze the outcomes of VF patients managed by EMT-Ds without paramedic backup.
• To assess the effectiveness of EMT-Ds in managing refibrillation.
• To determine if paramedic backup is essential for managing refibrillation.

Main Methods:

• Retrospective analysis of 271 cases of VF managed by EMT-Ds.
• Focus on 111 patients initially converted to organized rhythms.
• Evaluation of refibrillation rates, reconversion, hospital admission, and discharge rates.

Main Results:

• 17% of initially converted patients refibrillated.
• 58% of those who refibrillated were successfully reconverted to perfusing rhythms.
• Hospital admission rates were lower for patients who refibrillated, but discharge rates were similar.
• Transport times did not correlate with refibrillation or outcomes.

Conclusions:

• Defibrillation-trained EMTs can effectively manage refibrillation with additional defibrillation.
• EMT-Ds are not at a significant disadvantage without paramedic backup for managing VF and refibrillation.
• The study supports the independent capability of EMT-Ds in advanced cardiac life support scenarios.
