From the Guidelines

Management of severe malnutrition requires a comprehensive, phased approach, starting with stabilization and careful refeeding to prevent refeeding syndrome, as recommended by the ESPEN guidelines 1. The initial treatment should focus on stabilization with careful refeeding, starting with small, frequent meals providing 20-30 kcal/kg/day, gradually increasing to 70-100 kcal/kg/day over several days.

  • Correct electrolyte imbalances by supplementing potassium (40-60 mEq/day), phosphate (0.5-0.8 mmol/kg/day), and magnesium (8-16 mEq/day) 1.
  • Administer thiamine 100 mg IV or orally daily for at least 3 days before initiating carbohydrate feeding.
  • Provide micronutrient supplementation including a daily multivitamin, zinc (2 mg/kg/day), vitamin A (5000 IU/day), and folate (1 mg/day).
  • Treat concurrent infections with appropriate antibiotics, as infections often accompany severe malnutrition.
  • Monitor vital signs, weight, fluid balance, and electrolytes daily during the initial phase. Once stabilized, transition to rehabilitation with increased caloric intake and protein (1.5-2 g/kg/day) 1. This careful approach prevents complications like cardiac failure, fluid overload, and hypoglycemia that can occur with aggressive refeeding. Long-term management should address underlying causes of malnutrition and include regular follow-up to ensure continued weight gain and nutritional rehabilitation, as emphasized by the ESPEN guidelines 1.

From the Research

Patient Assessment

The patient's vital signs and physical measurements indicate severe malnutrition, with a BMI of 12.57 and weight percentage of 1.05.

  • Heart Rate (HR): 129
  • Respiratory Rate (RR): 44
  • Temperature (Temp): 97.7
  • Height (Ht): 32.25 inches or 81.92 cm
  • Weight (Wt): 18.6 pounds or 8.44 kg
  • Body Surface Area: 0.44
  • Oxygen saturation: 99%
  • Pain scale: 0

Management of Severe Malnutrition

According to 2, malnutrition can lead to increased mortality, complications, and length of stay in hospitals.

  • Nutrition assessment is essential for optimal patient care, especially for patients at high risk for malnutrition.
  • Appropriate intervention, such as nutrition counseling, oral diet, and oral supplements, enteral formula, or parenteral nutrition support, can improve health outcomes and reduce costs.
  • Early nutrition assessment and intervention are crucial for quality healthcare.

Detection and Treatment

3 suggests practical procedures for screening and treating malnourished or at-risk patients, including:

  • Identifying malnourished or at-risk patients
  • Setting nutrient targets
  • Choosing the route of feeding
  • Monitoring and assessing patients
  • A simple algorithm to facilitate the implementation of a nutritional care plan

Treatment of Acute Malnutrition

4 states that acute malnutrition in children can be managed with nutrition-specific interventions, such as counseling and ensuring household food security.

  • In cases of severe acute malnutrition and complications, inpatient treatment is recommended.
  • Secondary acute malnutrition should be managed by treating the underlying cause.

Importance of Nutritional Assessment

5 emphasizes the importance of nutritional assessment and treatment of hospital malnutrition, as it can lead to decreased morbidity and mortality.

  • A thorough awareness of the nutritional and metabolic status of hospitalized patients is crucial for patient care.
  • Nutritional depletion must be quickly alleviated to prevent serious drain on vital organs and tissues.

Promoting Food Intake

6 discusses dietary, food service, and mealtime interventions to promote food intake in acute care adult patients, including:

  • Individualized dietary treatment
  • Foodservices that promote point-of-care food selection
  • Protected mealtimes
  • Mealtime assistance provided by volunteers or dietary staff.
