To properly irrigate a wound, start by collecting the right supplies. You’ll need a wound irrigation tray to set all of your supplies and keep them sterile throughout the process. For longer drainage periods, a wound drainage collector may be required to hold the pus and blood that leaks out from the wound. Before touching the wound, be sure to properly wash and sanitize your hands as well as the supplies you’ll be using. This will help prevent infection and improve wound drainage.
