Sure, midazolam or ketamine can be used to calm a delirious or angry patient. But there's something about having to sedate a patient whose sedation you just intentionally reversed that should seem wrong on it's face. If your patients are routinely waking up unmanageable after getting naloxone, you are giving the naloxone wrong. You give just enough to restore respiratory drive, and no more. That way they slowly correct their hypoxemia and hypercarbia while they are still sleeping, and they don't have the huge sympathetic surge that can actually be life-threatening. Hitting someone with 2mg of naloxone right off the bat is a medication error, and the predictable result of that toxic dose of naloxone is an unhappy, puking, hypertensive patient.
Naloxone isn't a reliable reversal for benzos. You can find small studies and case series showing that all kinds of drugs have the ability to antagonize other drugs to some degree, even ondansetron. The effect isn't nearly potent enough or reliable enough to be included in any protocols though.
There's always the option to provide mechanical ventilatory support rather than naloxone, and there's no question that that is sometimes the best option, depending on the scenario. Broadly speaking though, I think properly dosed naloxone is generally a better, safer option. Airway placement has risks (not the least of which is that these patients are at high risk for aspiration) and requires more resources and closer monitoring once at the receiving facility.
Just place a NC and OPA or NPA (or provide ventilations if they are really hypoxemic) and give a small dose (0.1 - 0.4mg) of naloxone every minute or so until they start ventilating better and their Sp02 improves. You now have a calm, sedate patient who is breathing well. Monitor and transport. No versed, ketamine, or LMA needed. Easy peasy.
