Total Parenteral Nutrition Discontinuation During Oral Diet Advancement
Total parenteral nutrition should be stopped when the patient is established on adequate oral and/or enteral nutrition support. [1]
Discontinuation Criteria During Oral Intake Transition
PN should be discontinued once oral intake is adequate to meet nutritional requirements, with the indication for PN resolved. [1]
Stepwise Weaning Approach
PN discontinuation is commonly performed by tapering as oral intake improves, rather than abrupt cessation, to ensure continued adequacy of nutrition during the transition. [2]
Clinical Implication of Diet “Advancement” Without Adequacy
Oral diet advancement to clear liquids, full liquids, or soft foods does not by itself indicate readiness to stop PN unless intake is demonstrated to be adequate. [1]
Situations Requiring Continued PN
PN should be continued when oral intake is not adequate to meet nutrition requirements or when the underlying indication for PN has not resolved. [1]
