Posteriorly Tunneled Dialysis Catheters for Permanent Use in Cognitively Impaired Patients Undergoing Hemodialysis

Cognitively impaired patients often pull at their dialysis catheters when the catheters are tunneled over the anterior chest. To potentially circumvent this, a technique was developed that tunnels the catheter posteriorly, over the patient's shoulder. A total of 32 posteriorly tunneled catheters were placed in 12 patients. The mean catheter use interval was 164 days, with a total of 5,248 catheter use days. Indications for nonelective catheter removals were catheter dysfunction (n = 7; 23.3%), removal by the patient (n = 7; 23.3%), infection (n = 5; 16.7%), and inadvertent dislodgment (n = 1; 3.3%). Only six of the 12 patients were able to dislodge their catheters. The procedure described here reduced catheter manipulation and extended catheter viability in these patients.
