You're making some serious assumptions here. 1. The source of anxiety could be dealt with at the time. 2. The training would be applicable at the time. 3. A different approach would require no sedation. 4. There was time for a calming approach given what had to be done at the time.
Sure, we should improve things, but also when you end up in the ICU, the priorities are a bit different than during a routine doctor visit - we don't know whether that situation could be dealt with without any kind of restraints/sedatives.
