Do not use IV rehydration except in shock! It is difficult to estimate dehydration status in a severely malnourished child Assume all children with watery diarrhea may be dehydrated Use low sodium oral rehydration solution ReSoMal (WHO solution) Reassess frequently Watch for signs of fluid overload Stabilization phase (ER & day 1-7) Correct electrolyte imbalances Correct micronutrient deficiencies Treat/prevent infections Start cautious feeding Step 4: Correct electrolyte imbalances All children with SAM are relatively hypernatremic, hypokalemic and hypomagnesemic To treat: Use low sodium rehydration fluid Supplement potassium and magnesium Prepare food without salt Do not treat edema with a diuretic! Step 5: Treat/prevent infection The usual signs of infection are often absent (ie. fever) Routinely give: Broad spectrum antibiotics Measles vaccine if child is >6m and unimmunized If a specific infection is present, treat with the appropriate antibiotics Consider antimalarials or antiparasitics Step 6: Correct micronutrient deficiencies Do not give iron initially as it may make infections worse Give vitamin A orally on day 1 Also give the following supplements: Multivitamin Folic acid Zinc Copper Iron – only start after the child is gaining weight Step 7: Start cautious feeding Small frequent feeds should be started as soon as possible Calories: 100 kcal/kg/day Fluid: 130 mL/kg/d F75 is starter formula (75kcal/100mL) Feeds should be given orally or NG (not IV) Continue breastfeeding in addition to formula supplementation Feeding schedule Days Frequency Vol/kg/feed Vol/kg/d 1-2 q2h 11mL 130mL 3-5 q3h 16mL 130mL 6-7+ q4h 22mL 130mL Treatment of associated conditions: Emergency treatment of shock Parasitic worms Ongoing diarrhea Emergency treatment of severe anemia Dermatosis Tuberculosis What is the emergency treatment of shock?

Blood transfusion criteria: Hemoglobin (Hb) less than 4 g/dL Respiratory distress and Hb 4-6 g/dL Treatment Whole blood 10 mL/kg slowly over 3 hours Furosemide 1 mg/kg IV at the start of the transfusion Monitor vital signs closely How should dermatosis be treated? Zinc deficiency is common Skin improves quickly with zinc supplementation Apply barrier cream to raw areas Zinc and castor oil ointment Petroleum jelly Paraffin guaze Omit diapers so perineum can dry How should we treat vitamin A deficiency in SAM? If the child has eye findings: Give oral vitamin A on days 1, 2 and 14 If there is corneal clouding or ulceration: Instill chloramphenicol or tetracycline eye drops (1%) every 2-3 hours for 7-10 days Instill atropine eye drops (1%) TID for 3-5 days Cover with eye pads soaked in saline and bandage How should we treat parasitic worms? Mebendazole 100 mg orally BID for 3 days or equivalent in your local area eg. Albendazole What are the causes of ongoing diarrhea? Diarrhea should improve during the first week of treatment Ongoing diarrhea: Mucosal damage Giardia Lactose intolerance Osmotic diarrhea What about tuberculosis? If significant TB contact or clinical findings Perform Mantoux test CXR If positive result or strong clinical suspicion Treat according to national TB guidelines Summary Undernutrition contributes to 1/3 of all childhood deaths worldwide Undernutrition is preventable Immediate, underlying and social causes must be addressed Micronutrient deficiencies are an important comorbidity of undernutrition Mortality can be reduced by following standard protocols for assessment and management of undernutrition Thank you!!! Addendum: Treatment of Undernutrition beyond the Emergency Room Rehabilitation phase (weeks 2-6) Achieve catch-up growth Provide sensory stimulation & emotional support Prepare for followup after recovery Step 8: Achieve catch-up growth Readiness to enter this phase is signaled by a return of appetite Gradually replace F75 with F100 100 kcal/100 mL and 2.9 g protein/100 mL Monitor closely for signs of heart failure Aim for weight gain >10 g/kg/day Step 9: Provide sensory stimulation and emotional support Children are often developmentally delayed in the setting of severe undernutrition Encourage: A happy and stimulating environment Structured play time Physical activity when well enough to participate Encourage parental involvement and counsel around development Step 10: Prepare for follow-up after recovery Recovery occurs when weight for length is -1SD below the mean Counsel the parents on feeding practices and sensory stimulation prior to discharge Follow-up: Regular check-ups Ensure booster immunizations are given Give vitamin A every 6 months What if the child does not gain weight as expected? Inadequate feeding HIV/AIDS Specific nutrient deficiency Psychological/devel opmental problems Untreated infection When should we discharge from facility-based treatment? Recovery when child reaches -1 SD weight for length Transfer to community-based program when: Good appetite Acceptable intake of RUTF (>75% or target) Reduced edema However… We must address the underlying causes of undernutrition It is also a social disorder If viewed as only a medical disorder than the child is likely to relapse when he goes home Other children in the family are also at risk Community follow-up plans are crucial… Evidence-based strategies that work: Exclusive breastfeeding for first 6m of life Complementary feeding /weaning education Improving water sanitation and hygiene Prevention first… Improve access to high quality foods Improve access to health care Improve nutrition and health knowledge Quiz Question 9 Which of the following is true: a) An undernourished child is more likely to have a reduced income as an adult b) The effects of undernutrition on cognitive development are reversible with proper nutrition c) More than half of all countries are on track to accomplish the Millennium Development Goals d) The effects of undernutrition on growth stunting are reversible with proper nutrition Quiz Question 9 Which of the following is true: a) An undernourished child is more likely to have a reduced income as an adult b) The effects of undernutrition on cognitive development are reversible with proper nutrition c) More than half of all countries are on track to accomplish the Millennium Development Goals d) The effects of undernutrition on growth stunting are reversible with proper nutrition What are the long-term morbidities associated with undernutrition?
