My dad has an open head wound that will not close completely. He had a skin graft the other year to close the wound, but even with hyperbaric treatments, it has not completely closed. Wound care is suggesting another operation to close the wound, but the skull looks dark and damaged.
I'm concerned about what type of anesthesia (and the amount) should be used as I don't want my dad to have dementia problems as a result. He's got good memory but does get a little confused at times.
Thank you for your input.
