You were put out by a nurse anesthesiologist.
Execution needles are basically administered by people off the street. Doctors and nurses typically dont participate.
So its given by someone untrained in administering it and no knowledge of dosage and are at a complete loss to correct if something goes the slightest bit awry.
Kinda hard to know when somethings not working right when youre not monitoring blood has levels, etc.
A Nurse anesthetist, not an ologist.
