In specific ulcer care it is important to establish how to treat the wounded tissue and the skin near the wound ( periwound area ). The use of disinfectant agents on ulcers is absolutely not indicated, the studies carried out show that the chemical components present in the antiseptic solutions are harmful to the multiplying cells and therefore their use should be abolished and replaced with non-harmful substances that have characteristics similar to the injured skin and that are able not to interfere with the reproduction processes (mitotic) in progress on the wound surface .
The solution saline, Ringer's lactate (product available in pharmacies) or alternatively the ' water faucet can safely be used for cleaning of ulcers.
An ulcer should be flushed with a 35 ml disposable syringe fitted with an 18 gauge needle, by sprinkling water towards the wound . The pressure measured in PSI ( irrigation surface pressure ) is about 8 PSI; this pressure carries out an effective cleansing without damaging the tissues and without pushing (inoculating) the bacteria deeply. The jet must be directed tangentially to the skin and the water should preferably be lukewarm (be careful not to cause burns ).
