If it becomes part of practice to order urine electrolytes at the time that someone's doing their TPN blood work, it's easy to calculate the fractional excretion of sodium ratio. — Paul Wales, CAPS - The use of urine sodium to creatinine ratio as a marker of total body sodium in infants with intestinal failure - Sara Choi · 7:12
Patients should be referred to intestinal rehabilitation programs when not making progress, on prolonged TPN, or have significant comorbidities, preferably sooner rather than later. — Stephanie Oliveira, Advancements in Pediatric Intestinal Failure: Innovative Therapies and Improved Outcomes · 4:19
Patients who transitioned to adult care had a significantly higher mortality rate of 33% compared to 5% among those who stayed in pediatric care — Julian Goddard, Care transition from a pediatric intestinal rehabilitation program to adult care and the risk of all-cause mortality: A retrospective cohort study · 0:29
Dr. Wales defined intestinal failure as a functional problem where gut function is insufficient to absorb enough nutrients, fluids, and calories to support survival and, in children, growth. He noted that until recently there was no standardized definition for the condition. Dr. Wales identified that causes of intestinal failure can be divided into three categories, though some patients present with elements of two or all three categories. He also described intermediate and longer-term complications including intestinal failure-associated liver disease, recurrent sepsis, and line problems.
- Preserved ileum and colon are the strongest anatomic predictors of autonomy via GLP-2 secretion, bile reclamation, and colonic short-chain fatty acid production.
- SMOF lipid at 2–2.5 g/kg/day prevents cholestasis without essential fatty acid deficiency; soybean lipid >2.5 g/kg/day increases liver disease risk 3% per day.
