Severe acute malnutrition with oedema: a mother who wants to go home
A 20-month-old girl is brought to a rural health centre by her mother, who has walked 12 km. Weight is 8.1 kg, length 76 cm, mid-upper arm circumference 10.7 cm, with bilateral pitting oedema of both feet and legs to mid-shin, visible severe wasting, sparse hypopigmented hair and no skin breakdown. She is alert but irritable, refuses food, and has had four watery stools today without blood or vomiting. Temperature is 36.4 degrees Celsius axillary, random blood sugar 68 mg/dL, haemoglobin 8.2 g/dL, no jaundice. There are no dehydration signs: eyes normal, tears present, mouth moist. The centre has ORS, amoxicillin, vitamin A, F-75 and F-100 milk, but no inpatient bed free until tomorrow morning. The mother wants to take the child home today with some sachets because two other children are alone at home.
1. Classify this child's nutritional status and list the immediate problems that must be addressed in the first hours.

She has severe acute malnutrition: mid-upper arm circumference below 11.5 cm, weight-for-length far below the severe threshold, visible severe wasting, and bilateral pitting oedema. The oedema makes this the oedematous (kwashiorkor-type) form, which carries a high mortality risk and changes management - oedema in severe acute malnutrition is not treated with diuretics, it resolves with therapeutic feeding and treatment of infection.
The immediate priorities in the first hours are the ones that kill children in the first 48 hours. Hypoglycaemia: a blood sugar of 68 mg/dL is borderline in a child who is refusing food and has diarrhoea, so give a glucose feed or, if she cannot take orally, intravenous dextrose, and feed two-hourly including through the night. Hypothermia: 36.4 degrees Celsius is low-normal and she has little subcutaneous fat, so keep her covered and warm and recheck. Infection: signs are masked in severe acute malnutrition, so give broad-spectrum antibiotics empirically rather than waiting for a focus. Feeding: start F-75, not F-100. Micronutrients: vitamin A as per protocol, potassium and magnesium supplementation, and no iron in the stabilisation phase. Dehydration: she has no clinical signs, so oral rehydration only - intravenous fluids are hazardous here because of the risk of heart failure.
2. The mother wants to take her home today. Argue the decision and describe what you would actually arrange.

Sending her home today with sachets would be unsafe, and I would say so plainly but respectfully. The first 48 hours carry the highest mortality, and every one of the risks that kills these children is present: borderline hypoglycaemia, borderline temperature, an infection that is likely being masked, oedema, and a child who is refusing food. F-75 must be given in small frequent feeds, including at night, and the mother cannot judge the onset of refeeding problems or heart failure at home 12 km away. Oedema can progress rapidly, and diarrhoea can tip her into dehydration within hours.
However, refusing the mother without offering a workable plan is also a failure. The practical solution is to keep the child in the facility today, even without a formal bed - a mat in the short-stay area with the mother beside it - start F-75 and antibiotics, and reassess in 24 hours when a bed is free. If the centre genuinely cannot hold her, then arrange the shortest possible supervised option: give the first F-75 feeds on site, teach the mother exact volumes and frequency with a marked cup, provide a one-day supply, and arrange a named health worker visit or return the next morning with transport. What must not happen is an unsupervised discharge with powder alone and no follow-up date.
3. Outline feeding over the next 48 hours and name two complications you would watch for, with the reason for each.

In the stabilisation phase, F-75 at about 130 mL/kg/day (roughly 100 kcal/kg/day), divided into eight feeds of about 130 mL each, given two- to three-hourly around the clock. Because she has oedema, the lower end of the volume range is appropriate. Continue breastfeeding if she is still nursing. Reassess appetite, oedema, temperature, stool frequency and weight twice daily; weight may fall as oedema resolves, and that is expected rather than a failure.
Only once appetite has returned and oedema is resolving do you transition, gradually over two to three days, to F-100 or a ready-to-use therapeutic food with a planned increase in volume. Advancing too early is the classic error.
Two complications to watch for. First, refeeding syndrome and cardiac failure: as feeding increases, intracellular shifts of potassium, magnesium and phosphate occur, and the malnourished myocardium cannot handle a rapid volume load. A rising pulse or respiratory rate, new basal crepitations, a gallop or an enlarging liver means stop advancing and treat for heart failure. Second, hypoglycaemia and hypothermia, which in this child are already borderline; both reflect depleted glycogen and energy reserves and are signs of infection until proven otherwise, so each episode should trigger a search for a source rather than just a sugar feed. Iron is deliberately withheld early because free iron worsens infection risk.
