Catheter (Central Venous Catheter) Catheter care training is provided to our patients who are receiving the hemodialysis treatment with Central Venous Catheter in our clinics. Furthermore, our patients are evaluated regarding catheter infections and their catheter care is performed after the treatment. During catheter care, personal, sterile equipment is used for one session. Also, catheters are inserted free of charge in private hospitals contracted within the SSI for our patients who are having problems with their catheters.
