Questions About PD
We thank you for your question. We are not aware of best practice guidelines that address how long a PD catheter can remain in place before it is used. You do not provide much information, but, we presume, the situation you are asking about is for when the plan is for the patient to start PD, has a PD catheter in place, but is not yet ready to start PD.
We would strongly recommend, however, that you do follow the ISPD guidelines on chronic PD catheter exit-site care, including daily topical application of an antibiotic ointment to the catheter exit site (1, page 114). Also, you should teach your patient to monitor for signs and symptoms of a PD catheter exit-site infection and to notify the home PD unit if he or she has concerns about the exit site. A PD catheter exit-site infection is a well recognized risk factor for developing peritonitis.
