I have worked with burns on/off for 15 years. The thing that amazed me is that if you medicate well enough, they state the treatments were fine. I took care of a 98% who screamed bloody murder and cursed me and everything to do with me during the debridements. After 2 hours in the tub room and then the 1 hour to complete the dressing change, I took a much needed break and when I returned he always said the dressing change was a piece of cake, thank you!
I love concious sedation and dilaudid push!
Now I work in a neuro ICU and its similar, causing pain. You do get used to it, but always be proud of the pain relief that you can bring them. Never shirk your duty to control it, just because you have a better tolerance for causing it.
