What is refeed syndrome?
Refeeding syndrome can be defined as the potentially fatal shifts in fluids and electrolytes that may occur in malnourished patients receiving artificial refeeding (whether enterally or parenterally5). These shifts result from hormonal and metabolic changes and may cause serious clinical complications.
What is the pathophysiology of refeeding syndrome?
The pathophysiology of refeeding syndrome has now been established. In starvation the secretion of insulin is decreased in response to a reduced intake of carbohydrates. Instead fat and protein stores are catabolised to produce energy. This results in an intracellular loss of electrolytes, in particular phosphate.
How do you treat refeeding syndrome?
What are the treatment options? People with refeeding syndrome need to regain normal levels of electrolytes. Doctors can achieve this by replacing electrolytes, usually intravenously. Replacing vitamins, such as thiamine, can also help to treat certain symptoms.
Which electrolytes decrease in refeeding syndrome?
Refeeding syndrome involves metabolic abnormalities when a malnourished person begins feeding, after a period of starvation or limited intake. In a starved body, there is a breakdown of fat and muscle, which leads to losses in some electrolytes like potassium, magnesium, and phosphate.
When does refeeding syndrome occur?
Refeeding syndrome usually occurs within four days of starting to re-feed. Patients can develop fluid and electrolyte imbalance, especially hypophosphatemia, along with neurologic, pulmonary, cardiac, neuromuscular, and hematologic complications.
Why is thiamine used in refeeding syndrome?
THIAMINE IN REFEEDING SYNDROME 5,14 Thiamine deficiency is likely in refeeding syndrome because of increased metabolic needs. Thiamine is required as a co- factor in many of the metabolic pathways that are upregulated once feeding is reinitiated.
What is refeeding syndrome with TPN?
Refeeding syndrome results from rapid changes in fluids and electrolytes when initiating nutrition in previously malnourished patients. As mentioned above, patients who suffer from refeeding syndrome are usually hypophosphatemic, as well as hypomagnesemic and hypokalemic.
What happens to electrolytes in refeeding syndrome?
The changes can throw off the balance of electrolytes and fluids in their bodies. During refeeding, your metabolism can start to overproduce insulin, which triggers your body to synthesize protein and produce fat. The process can monopolize the electrolytes in your body.
How is refeeding syndrome diagnosed?
According to these guidelines, patients at the highest risk for refeeding syndrome meet one or more of the following criteria:
- Body mass index (BMI) under 16;
- Weight loss of more than 15 percent of his or her body weight in the past 3 to 6 months;
- Little to no food for the past 10 or more consecutive days; or.
How is refeeding syndrome prevented?
Complications of refeeding syndrome can be prevented by electrolyte infusions and a slower refeeding regimen. When individuals who are at risk are identified early, treatments are likely to succeed.
Can IV dextrose cause refeeding syndrome?
3.1 Recognising Risk of Refeeding Syndrome Risk is increased in patients who are given TPN or IV dextrose, as these are rapidly- administered parenteral carbohydrate which speeds the metabolic effects. However, patients receiving enteral feeding or oral diet can also be at risk.
Why does TPN cause refeeding syndrome?
What labs check for refeeding syndrome?
Plasma electrolytes, in particular sodium, potassium, phos- phate, and magnesium, should be monitored before and during refeeding, as should plasma glucose and urinary electrolytes.
What is ICD 10 refeeding?
There is no documentation of any specific electrolyte imbalances, only the term ‘refeeding syndrome’. E87. 8 Other disorders of electrolyes and fluid balance, not elsewhere classified is the code suggested by www.icd10data.com/ICD10CM/Codes/E00-E89/E70-E88/E87-/E87.
Why is thiamine used in refeeding?
Vitamin deficiency Starvation will usually result in several vitamin deficiencies. The most important of these with respect to refeeding is thiamine, as it is an essential coenzyme in carbohydrate metabolism.
Why is thiamine important in refeeding syndrome?
Why is thiamine low in refeeding syndrome?
5,14 Thiamine deficiency is likely in refeeding syndrome because of increased metabolic needs. Thiamine is required as a co- factor in many of the metabolic pathways that are upregulated once feeding is reinitiated.
