severe Acute Malnutrition

Q: What is the MUAC cut-off for diagnosing Severe Acute Malnutrition in children 6-59 months?

According to the diagnostic criteria, MUAC < 11.5 cm in children 6-59 months is one of the criteria for SAM. Any ONE of the diagnostic criteria is sufficient for SAM diagnosis.

Q: Which of the following is a characteristic feature of Marasmic SAM?

Non-edematous SAM (Marasmus) is characterized by severe wasting, no edema, decreased subcutaneous fat, 'old man' appearance, and the child being alert and hungry.

Q: What is the caloric content of F-75 therapeutic formula?

F-75 contains 75 kcal/100ml and is used during the initial stabilization phase. The rationale is to avoid high protein early in treatment.

Q: Why is iron NOT given in the early treatment of SAM?

Iron is withheld initially because it's decreased HB synthesis not iron deficiency, free iron causes free radicals, and iron storage requires energy and amino acids that are limited in SAM.

Q: What electrolyte management is recommended in SAM?

The management principle states to give K+ and restrict Na+. This is because SAM patients have sodium retention and potassium loss as part of their systemic changes.

Severe acute malnutrition is a life-threatening nutritional emergency in children characterized by severe wasting, stunting, or bilateral pitting edema, diagnosed when weight-for-height Z-score falls below -3 SD or MUAC is less than 11.5 cm in children 6-59 months. The condition triggers profound reductive adaptations across all organ systems, including decreased cardiac output, impaired immune function, and metabolic derangements that make these children extremely vulnerable to hypoglycemia, hypothermia, infection, and refeeding syndrome. Medical students must understand the WHO 10-step management protocol, particularly the principle of "do no harm" during stabilization, which emphasizes cautious feeding with F-75, avoiding iron initially, and treating infections empirically before transitioning to rehabilitation with catch-up growth formulas.
