Lethargic toddler with edema, diarrhea and hypoglycemia in a rural health post
A 14-month-old boy is brought to a rural health post with five days of watery diarrhea and poor feeding. He was exclusively breastfed for four months only and has been fed mainly rice water since. He is lethargic and has pitting edema of both feet. Weight 6.2 kg, length 72 cm, mid-upper-arm circumference 10.8 cm. Temperature 35.7°C, pulse 130/min, respiratory rate 36/min, capillary refill 2 seconds. Blood glucose by glucometer is 42 mg/dL. He has sunken eyes and a slow skin pinch, but is not in shock. There are no eye signs of vitamin A deficiency and no obvious infection. The health post has oral rehydration salts, ready-to-use therapeutic food, and a supply of intravenous fluids but no laboratory.
1. How would you classify his nutritional status and what are the immediate life-threatening priorities?

This child has severe acute malnutrition with edema (kwashiorkor): weight-for-length is far below −3 SD, MUAC 10.8 cm (below 11.5 cm), and bilateral pitting edema. The immediate life-threatening problems are hypoglycemia (42 mg/dL), hypothermia (35.7°C), and probable dehydration with lethargy. He is not in shock (capillary refill 2 seconds, no cold extremities), so do not give rapid boluses. Priorities in order: treat hypoglycemia with 10% dextrose 5 mL/kg IV immediately, then start frequent feeds; warm the child using skin-to-skin contact or a warmed room; give oxygen if saturations are low; and start oral rehydration with ReSoMal. Check for other complications: no eye signs of vitamin A deficiency, but look for mouth ulcers, skin changes, and infection. Because there is no laboratory, rely on clinical signs and do not delay antibiotics. The edema is not a reason to restrict protein severely; it reflects malnutrition and associated hypoalbuminemia and infection.
2. Outline your fluid plan for dehydration and hypoglycemia, and explain why you would avoid rapid intravenous boluses.

Hypoglycemia: give 10% dextrose 5 mL/kg IV (about 30 mL) and recheck glucose in 30 minutes; then feed F-75 immediately and every 2–3 hours, including at night. Dehydration: because there is no shock, use oral ReSoMal 5 mL/kg every 30 minutes for 2 hours, then 5–10 mL/kg/hour for up to 10 hours, reassessing frequently. Stop when the child is rehydrated and passing urine. Avoid intravenous fluids unless shock develops; if shock is present, give 15 mL/kg of Ringer’s lactate with 5% dextrose over 1 hour and reassess. Why: children with severe malnutrition have impaired cardiac reserve and easily develop fluid overload and heart failure; rapid IV fluids can kill. ReSoMal has lower sodium and higher potassium than standard oral rehydration salts, which suits the electrolyte profile. Monitor pulse, respiratory rate, liver size, and urine output during rehydration.
3. What feeding and medicines would you prescribe in the first 48 hours, and what would you avoid?

Start F-75 therapeutic milk at about 130 mL/kg/day divided into 6–8 feeds; if edema is marked, start at 100 mL/kg/day. Continue breastfeeding if the child is breastfed. Do not use high-protein or high-energy feeds in the stabilisation phase; avoid iron, because free iron can worsen infection and hemolysis. Give vitamin A 200,000 IU orally (age 12–59 months) if not given in the last month, folic acid 5 mg on day 1 then 1 mg daily, zinc 20 mg daily for 10–14 days, and potassium chloride and magnesium supplementation as available. Because infection is common and often hidden, give broad-spectrum antibiotics: ampicillin plus gentamicin, or ceftriaxone if available, for at least 5–7 days. Treat hypoglycemia and hypothermia as emergencies. Avoid diuretics for edema and avoid rapid rehydration. Reassess daily for weight, edema, feeding, and signs of heart failure; transition to F-100 only after stabilisation.
