Couple of points....
First, read your protocols regarding restraints. In our system, by our protocols, we are not allowed to transport in handcuffs unless there is no other option and the failed attempts to use other methods needs to be documented in the report.
Second, not all drunks are combative, not all drunks are unconscious, not all drunks are without significant health issues that need to be evaluated/treated.
Being authorititative with a belligerent drunk is more likely to escalate the situation than solve the problem.
We need to treat medical conditions, not situations. If I have an unconscious pt, I'm going to treat them pretty much by the same protocol, regardless of what particular method got them there. My issue is the unconsciousness. Any unconscious pt has the possibility of vomiting. The drunk with a belly full of Jack Daniels isn't much different than the other non drinking patient who just ate a big meal except that the aftermath might smell a bit worse in the first case. (Damn I hate that smell!!!)
Treating a pt with respect for their humanity is a core skill. I can be anyone's best friend for the time it takes to transport them to the ER. I can put aside my personal likes, dislikes, political beliefs, religious preferences, and moral code for the duration of a call. I don't have to agree with the patients life choices in order to treat them with respect. To be honest, direct, polite, and socially acceptable.
Drug or alcohol abuse may turn them into an a*****e but that doesn't mean I have to become one as well. This particular philosophy has been extremely effective in minimizing the confrontations between myself and those under the influence of chemicals. Case in point, the other night, we were toned out to 'man unconscious in highway' Arrived to find unconsious 40 something year old male, passed out 2am, on the highway. Two lane state highway, about 36 degrees out.... Raining...Guy reeked of possible ETOH. No LEO available. We were told that the sheriff's deputy was responding to another call and the troopers (state highway, their jurisdiction) would be enroute "after he got into his car" at a location 48 miles east of us.
The first volunteers on scene were unable to get any information from the guy. He did sit up and talk to them. Told them he was fine and to leave him alone. He was mildly combative, uncooperative, and mildly beligerent.
Guy is refusing treatment. But, if he's really drunk (ie. drunk enough to pass out in the middle of a highway) can he give legal refusal? Those first on scene were demanding his name. They were standing above him, speaking in loud, declarative statements. "We need your name!" "What are you doing here?" "You have to... ", "You must....." and they were getting absolutely no where.
In five minutes I had not only his name, but his DOB, last known address, a short medical history and enough information to determine his fitness to decline treatment. I made him promise to stay far enough off the road to avoid getting hit. To stay safe and in the future, to move further off the highway if he needed to take a nap. He shook my hand, thanked me and went on his way.
The big difference was instead of demanding his name, I put my hand out and introduced myself.. My name is.. and what's yours? Instead of an interrogation, it was a social exchange.
There will be exceptions. But our approach can turn the exception into the rule.
