Hubby had robotic prostatectomy last Thursday. He has the standard 6 "port" wounds, all with adhesive dressings. The ward changed them before he was sent home last Friday morning, and gave us some spares in case any came loose. They are all looking dry and no sign of anything "nasty" but all discoloured and dirty looking now. Not due to have staples removed until next Thursday. I would like to change them, give wounds a wipe with boiled water just to freshen them up, but he thinks there is no need. Any advice please?
