Initial patient education includes how to assess the exit site, including visual inspection and palpation of the tunnel, recognizing signs and symptoms of exit site infection, and when to notify the PD unit of exit site problems. Catheter exit sites are washed daily with liquid, antibacterial soap. It is important not to forcibly remove crusts or scabs during cleansing because this may traumatize the exit, causing a break in the skin and increasing the risk of infection. Pat the exit dry after cleansing. It's not necessary to use sterile gauze or cotton-tipped applicators for care of the healed exit; a clean washcloth and towel work well. Sudden or extreme traction on the catheter are to be avoided to prevent extrusion of the external cuff. Whether to wear a dressing or not is based solely on individual preference. However, the use of dressings may help keep the exit clean, protect it from trauma, and help to stabilize the catheter.
