The paramedics and hospital probably had her on drugs the second she got into the ambulance.
I answered on an earlier thread hypothetical about a person in a car crash and they have them doped up to manage their pain. They still proceed with it harvesting.
It's only a doctor who can order meds and that's after blood work is done. In an extreme case of pain or injury a doctor might immediately order that. But if a patient is in respiratory distress sedating them can be tricky.
It may make things worse.
