I was using sugar paste in the early nineteen eighties for bed sores in care of elderly. I remember a meeting with surgeons to try to stop them using Eusol (Edinburgh Universal Solution?) and move to sugar. Eusol was best for cleaning bedpans, not healing wounds! I'm ashamed to say I was not persuasive enough that time. There was great support from pharmacy and the director of nursing and there was research evidence but we got bumped!
