I'm looking at how burns and physical trauma affect potassium levels in the blood, and I'm seeing some opposing information. In trying to put this together, I thought I'd ask someone here what they think. What I think is correct is, broadly:

1. A deeper physical trauma without extensive bleeding will result in hyperkalemia, due to potassium in the broken cells flooding the blood.
2. Superficial burns (not all the way through the epidermis) or an open and draining wound can cause hypokalemia due to the potassium leaving the body.
3. More extensive/deep burns can initially cause hyperkalemia in the initial period (resuscitation phase?), but after this (acute phase?) the individual can have hypokalemia due to fluids being given to them diluting out potassium and possible vomiting that can occur in burn victims.

Is this right, or is something off? I've based this on reliable sources, but most of them focus on just one of these or say either/or without giving an explanation.
