CASE 3 — SAIO: WHEN DO YOU SAY “START PN”?
A 67-year-old man with three previous abdominal surgeries is admitted with recurrent subacute intestinal obstruction (SAIO).
CT shows:
- Dilated small-bowel loops
- Transition point in distal ileum
- No bowel ischemia
- No perforation
- No collection
He is being managed conservatively with NG decompression.
Nutrition assessment:
- BMI: 18.6 kg/m²
- Unintentional weight loss: 9% in 3 months
- Minimal oral intake for 7 days
- Currently NPO
- Marked muscle wasting
- CRP: 42 mg/L
By day 5, the obstruction has not completely resolved.
NG output remains significant.
The surgical team expects that oral/enteral feeding may not be possible for several more days, although surgery is not currently planned.
What is the MOST appropriate nutrition strategy?
