MARASMUS AND KWASHIORKAR
CASE SCENARIO
Ram a 18 month old boy was brought to hospital with c/o poor weight gain. He was 2.5 kg at birth and 5 kg at 5 months of age but was given poor quality complementary feeding.
His admission weight was 6.8 kg with a length of 64 cm.He was started on treatment protocol for SAM patients.His glucose and temperature stabilized over the next 24 hours.
On Day 3 ,he suddenly deteriorated with respiratory distress and hypotension and required PICU care.
WHAT IS REFEEDING SYNDROME?
Clinical complex, which includes electrolyte changes associated with metabolic abnormalities that can occur as a result of nutritional support ( enteral or parenteral), in severely malnourished patients.
Also called “the hidden syndrome”
History
PATHOPHYSIOLOGY
CLINICAL MANIFESTATIONS
Nausea, vomiting, and lethargy
Respiratory insufficiency, cardiac failure, hypotension, arrhythmias, delirium, coma, and death
DEFICIENCY CLINICAL FEATURES CORRECTION
Hypophosphataemia(Normal 0.8 to 1.45 mmol/L)
heart failure, arrhythmiaacute tubular necrosis, metabolic acidosisRhabdomyolysisSeizures,Coma
0.1 – 0.36mmol/kg/day up to 1.5mmol/kg/day Phosphate IV [Max70mmol/day]
Oral Joules solution
Hypomagnesemia(Normal 0.77–1.33 mmol/l)
Arrythmias,Hypoventilation,Weakness,Vomiting,Loose motions.
0.6mmol/kg/day Magnesium Sulphate (IV)
Thiamine Wernicke-Korsakoff syndrome, psychosis,congestive heart failure, beriberi,
1ml (equivalent to 100mg thiamine) should be administered in 50-100ml 5% dextroseover 30 minutes
REFEEDING SYNDROME
Refeeding a malnourished patient can result in Heart failure due to:
Atrophic myocardium in malnutrition
Muscle depletion of Mg, K, P
Sodium and water overload
MANAGEMENT
Feeding and correction of biochemical abnormalities can occur in tandem without deleterious effects to the patient.(NICE)
Early identification of at risk individuals,
Monitoring during refeeding , and
An appropriate feeding regimen are important.
CLINICAL MONITORING
Monitor blood pressure and pulse rate Monitor feeding rate Meticulously document fluid intake and
output Account other sources of energy (dextrose,
medications) Monitor change in body weight Monitor for cardiac,respiratory and neurologic
signs and symptoms
LAB MONITORING
Monitor biochemistry and electrolyte levels(initially 12 hourly).
Monitor blood glucose levels. ECG monitoring in severe cases.

Principle of Permissive Underfeeding
50 percent of estimated caloric requirement.
Dietician consult essential.
Avoid glucose/Carbohydrate overload

REFEEDING SYNDROME-TAKE HOME MESSAGE
Children with SAM are at high risk of refeeding syndrome (especially children who have SAM with edema).
Feeds should be started cautiously and gradually with MONITORING (both clinical and lab)
Hypophosphatemia ,Hypomagnesemia ,Hypokalemia and Thiamine deficiency can be life threatening and should be treated aggressively.

FOR BOTH SAM WITH EDEMA & WITHOUT EDEMA
Feed 2-hourly for at least the first day. Then, when little or no vomiting, modest diarrhea (<5 watery stools per day), and finishing most feeds, change to 3-hourly feeds.
After a day on 3-hourly feeds: If no vomiting, less diarrhea, and finishing most feeds, change to 4-hourly feeds.
