                                According to one review of clinical total parenteral nutrition (TPN) use, patients had a median survival of 1.5 years after initiation, though some survived much longer, demonstrating the wide variability in duration based on individual factors. So, how long can parenteral nutrition be used? The duration depends on the specific type of PN, the patient's underlying condition, and overall health.
