Early Versus Late Intubation Trial in Physician Manned Emergency Medical Services
A Prospective Randomized Controlled Trial Comparing Competent EARLY-intubation to LATE-intubation in Patients With Prehospital GCS < 9 and Short Transport Time to Hospital.
This study looks at advanced airway management in critically ill or injured patients treated by physician manned emergency medical services, comparing early (on-scene) intubation to late (emergency department) intubation.

The ELITE trial is a prospective randomized controlled trial (RCT) to compare competent EARLY-intubation to LATE-intubation in patients with on-scene Glasgow Coma Scale (GCS) < 9 and short ambulance transport times (< 20 min) to hospital.

The study aims to establish if advanced airway management with endotracheal intubation (ETI) in the field by specially trained Emergency Medical Services (EMS) physicians - compared to endotracheal intubation (ETI) performed by physicians in the emergency department in the same group - improves outcome in terms of 30-day mortality, degree of disability at discharge, complications and length of hospital stay, and neurologic outcome at 6 months.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Trauma
  • Craniocerebral Trauma
  • Intracerebral Hemorrhage
  • Seizures
  • Unconsciousness
  • Procedure: Early Intubation
  • Procedure: Late intubation
  • Active Comparator: Early Intubation
    Early intubation is defined as prehospital intubation on the scene of the patient illness/injury, or where the EMS physician first meets the patient (e.g en route to hospital). Intubation includes drug assisted and/or rapid sequence intubation (RSI) with endotracheal tube.
    Intervention: Procedure: Early Intubation
  • Active Comparator: Late intubation
    Late intubation is defined as on-scene prehospital high-flow (> 10 L/min) supplemental oxygen by mask, assisted bag-mask-ventilation by EMS physician if required and stable recovery position during transport to hospital. Intubation should be done on arrival in the emergency department.
    Intervention: Procedure: Late intubation
