Disinfectants are used to maintain sterility of the transfer set tip between exchanges and of the transfer set and PD catheter during a transfer set exchange. Disinfectants are no longer instilled in PD tubing since disposable tubings using the twin bags became available. Caps containing disinfectant are used with cycler tubings as well as with the transfer set tip when the patient is temporarily disconnected from the cycler. Disinfectants have a define role in maintaining the sterility of PD tubings and transfer set.
