This study conclusion states: “Prehospital epinephrine administration in patients with traumatic cardiac arrest was associated with increased survival to hospital discharge and prehospital ROSC.” When you investigate the methods, only 809 of the 22,105 patients in traumatic cardiac arrest actually received epinephrine. In the study country, EMS gets orders from base station physicians for epinephrine. Why did these 809 get the epinephrine and the other 97% did not? It is hard to know what to do with this data. It certainly doesn’t say epinephrine saves patients in traumatic cardiac arrest. More research is needed.
