If the eschar is dry and intact, with no surrounding erythema, then certainly I would leave it alone, especially if the patient is diabetic or has vascular issues- such care must be taken there. Letting the body do its job, on its own time, is often best. Check their supplements, MVI, how about their pre-albumin? Are they terminal? *However, at the first sign of erythema, drainage, etc, I would look closer at debriding, ATB etc. You have to wonder though, what are the hospitals in your area doing for prevention of these areas? Prevention is the BEST medicine, floating heels, barriers, etc. Perhaps you could put a plan of prevention in place?
