Methods and compositions for decontaminating PD catheters

A method of performing peritoneal dialysis (PD), the method comprising:

• delivering a PD fluid to a peritoneal cavity of a patient through a PD catheter;
• dwelling the PD fluid within the peritoneal cavity;
• and
• while dwelling the PD fluid, removing a biofilm from a PD catheter wall using a biofilm removing solution,
• wherein the biofilm removing solution consists of:
• sodium citrate dihydrate;
• citric acid anhydrous;
• an alkyl sulfonate;
• water;
• and
• an antimicrobial ingredient.

A method of performing peritoneal dialysis (PD), the method comprising:

• pumping a PD fluid including a biofilm removing solution to a peritoneal cavity of a patient through a PD catheter;
• dwelling the PD fluid including a biofilm removing solution within the peritoneal cavity;
• and
• while dwelling the PD fluid including a biofilm removing solution, removing a biofilm from the PD catheter wall via the biofilm removing solution,
• wherein the biofilm removing solution consists of:
• sodium citrate dihydrate;
• citric acid anhydrous;
• an alkyl sulfonate;
• and
• water.

A method of removing at least a portion of a biofilm present in a lumen of an indwelling peritoneal catheter while performing peritoneal dialysis therapy, the method comprising:

• delivering a dialysis fluid to a peritoneal cavity of a patient through the catheter;
• injecting a biofilm removing solution into the lumen of the catheter to occupy at least a portion of the lumen;
• dwelling the dialysis fluid within the peritoneal cavity;
• and
• removing at least a portion of the biofilm removing solution from the catheter by withdrawing at least a portion of the dialysis fluid from the peritoneal cavity into the catheter,
• wherein the biofilm removing solution consists of:
• sodium citrate dihydrate;
• citric acid anhydrous;
• an alkyl sulfonate;
• and
• water.
