I'm like Jim, I'm not going to judge as I wasn't there and I don't know what their protocols will or will not allow. I've been in the situation of having a patient considerably larger than me attempting to beat me up and it wasn't pretty. Didn't have the luxury of meds to give (basic at the time with basic partner) and pd was nowhere to be found. Yep we did some unconventional things to take control of the scene, but we had to. I certainly don't promote that, but if that's your only option, so be it.
Now - the flip side. One I'm wondering if the reporting is accurate (like it ever is but.... ) because I've dealt with many a seizure patient, and yes, they will become combative post ictal (or ictal if complex partials), but the aggression is usually not directed - this sounds pretty directed to me. Most of the time it's because you won't let them up and they become restless trying to fight to get up or you are blocking their path if they are wandering. I have yet (not to say it doesn't happen, but not yet to me at least) to have one intentionally hit me, and then continue to do so. Obviously yeah, I've been in the way of a swing or struggle to get up more than once, but not intentionally. Also - alot of times if you de-escalate the situation, make it more quiet and relaxed they will as well because they are simply disoriented (think about how people are when they first wake up - not totally with it and fuzzed - well that's the feeling). Should restraints have been utilized - yeah - perhaps wrist and lap restraints in addition to normal stretcher straps would have been considerably more beneficial than taking a swing. That likely only made things worse. All else fails, there are such things as backboards and spider straps (or backboards and restraints). Would have been much easier to justify and get out of hot water with the department and also the state than taking a swing. At a minimum people - you were in Chicago ! You can spit and hit a cop ! Let them be the ones to get in trouble dealing with a combative patient, not you. Protect yourself, protect your cert and if all else fails, let the guys with the guns be responsible for restraint. It can always be sorted out later. Also, this doesn't say whether meds were within range, but for a seizure patient, I think one could easily justify giving valium, versed, or ativan (versed and ativan IM) for sedation. I know many have bent the rules on combative seizure patients and utilized this with justification with no backlash.
Be safe, be smart, be wise out there.
