How is this intentionally performing a procedure known to be life threatening? I give propofol all the time for fracture/shoulder reductions. Yes, it can be a life threatening drug, but it's an acceptable risk. There's no law that states it has to be given in a healthcare setting. I could easily give it to a family member at their house if I wanted to if I had a legitimate reason (if they popped out their shoulder, elbow, etc.). Although I don't keep propofol nearby so that's not going to happen. The risk is people vomiting and aspirating or they go into respiratory arrest. The first is easily prevented by having suction nearby, or better yet not performing sedation on someone who has eaten within the last 4 hours. The second is treated by simply ventilating the patient for the 1-2 minutes it takes for the drug to wear off.
I've given people too much propofol before, had them stop breathing, and simply ventilated them for a minute and they were wide awake by then. Propofol wears off so quickly. I don't give it unless it's going to be a very simple procedure. For a complex fracture/dislocation, I usually use midazolam/fentanyl or etomidate instead because it lasts a little longer allowing me to manipulate the fracture.
I think I remember seeing a serial number on a propofol bottle once. Our bottles are barcoded, but the hospital places the barcode on them for nurses to scan for billing purposes. We use the 250 mL bottle to do our conscious/procedural sedations with. End up wasting a ton since the concentration is 10 mg/mL and nearly everyone can be knocked out with 100 mg (10 mL). Propofol is our drug of choice for sedating vent patients where I work now.
Physicians can order propofol through suppliers.
As I mentioned before, as long as they were using it for an acceptable purpose, then they won't be charged. Using it for insomnia then they likely will be charged.
