Who will be blinded {17a}
The ambulance staff is blinded when randomly picking the study medicine box after inclusion in the trial. The treating ambulance staff is unblinded after opening a study medicine box, yet the ambulance staff will not take any further part in the trial, nor the treatment of the patient once arrived at Rigshospitalet. All treating personnel at Rigshospitalet are blinded to the study medicine allocation. Infusion of the study medicine is completed before arriving at Rigshospitalet, and no information about the study medicine allocation will be given to the receiving hospital personnel. Therefore, all other personnel than the ambulance staff are blinded to the treatment allocation. The study medicine allocation will not be unblinded until completion of the entire trial.
