Why is perioperative nutrition optimization important and what is a common plan for malnourished patients?

• A. It has no impact on outcomes.
• B. Improves wound healing and immune function; provide preoperative nutrition support (enteral preferred; parenteral if needed) and plan postoperative nutrition.
• C. Nutrition is only important postoperatively.
• D. Enteral nutrition should not be used in surgical patients.

Answer: (B)

Perioperative nutrition optimization recognizes that the body responds to surgical stress with increased catabolism and inflammatory demands, so providing adequate calories and protein before and after surgery supports healing and the immune system. For patients who are malnourished, starting nutrition support before the operation helps rebuild reserves and reduces complications. Enteral nutrition is preferred when the GI tract is functional because it helps maintain gut integrity, lowers infection risk, and is usually safer and more cost-effective; if the gut cannot be used, parenteral nutrition is added to meet needs. The plan doesn’t stop at the operating room—postoperative nutrition should be continued and adjusted as the patient recovers to meet caloric and protein goals and to support wound healing and recovery.

So, this approach directly links improved wound healing and immune function with a practical plan: assess nutritional status, provide preoperative nutrition (enteral if possible, parenteral if necessary), and ensure a continued nutrition strategy after surgery. This is preferable to notions that nutrition doesn’t affect outcomes, is only important after surgery, or that enteral feeding should be avoided.
