I took an Wilderness First Aid course where we learned about how to set a compound fracture via traction, which obviously would be horrendously painful. I was wondering if you could use the sleeper hold to knock the person out for 10-15 seconds, and set the bone while they were unconscious. It seems like there would be risks relating to maybe blood pressure or shock, but could it work?
The sleeper hold is not an anesthetic. It's cutting off oxygen supply to the brain. To a patient who is hemorrhaging from a traumatic wound, no, it's probably not a good idea to cut off even more oxygen to their brain and vital organs. They will scream and hate you while you set the bone, but once it has sufficient traction, it will feel ok.
