In early post transplant nutrition, when might parenteral nutrition be favored over enteral nutrition?

• A. Enteral nutrition is always preferred over parenteral nutrition in early post-transplant patients.
• B. Parenteral nutrition may be favored when enteral nutrition shows no clear benefit or GI toxicity precludes enteral feeding.
• C. Parenteral nutrition is never used due to infection risk.
• D. Oral dietary modification alone is sufficient.

Answer: (B)

In the early post-transplant period, the goal is to provide enough calories and protein to support healing while keeping the gut safe and functioning. The gut is usually the preferred route because it helps maintain the intestinal barrier and lowers infection risk, but this only holds if the GI tract can tolerate feeding and if enteral nutrition actually provides benefit. Parenteral nutrition is favored when enteral nutrition offers no clear benefit or when GI toxicity or other contraindications prevent safe enteral feeding. In those cases, delivering nutrients intravenously ensures the patient’s metabolic needs are met without stressing a damaged or nonfunctional gut. So, parenteral nutrition is chosen to meet essential nutrition when enteral feeding isn’t feasible or beneficial, rather than using it universally or ignoring the gut’s potential role.
