Location, the main thing is to get in, correct the worst of the tissue/organ damage, then stablize patient. Meds, BP, heart rate all have to be considered. If the patient had blood loss, they will not want to linger in O.R. untill they can get him out of immediate danger and stabilized.
Have a daughter that was cut from the front passenger side of vehicle that rolled over 8 times. They do what they can do--then stabilize. Her bone fractures and cuts/abrasions were not the priority. Keeping her alive was.
