Haemodialysis patients with a tunnelled dialysis line, or PermCath, have a 2-3 fold increased risk of hospitilisation for infection compared to those with an arterio-venous fistula or graft (reference). For this reason, we strive to have AV fistulas created for as many patients as possible, with the Renal Association guidelines recommended that 60% of patients have a mature AV fistula ready for use by the time they commence dialysis (reference &#8211; Renal Association).\u00a0 <\/span><\/span><span style=\"font-family: arial, helvetica, sans-serif; font-size: 12pt;\"><span style=\"color: #000000;\">Infections associated with tunneled dialysis catheters can be fatal.

The priority is catheter removal. Pending surgery, yeasts should be treated with oral fluconazole 200 mg daily, continued for 2 weeks after catheter removal; other fungi may require amphotericin.
