Early nutritional depletion in critically ill children
Insights
Pediatric intensive care unit (PICU) patients often show signs of malnutrition. Protein-energy malnutrition (PEM) and nutrient deficiencies are common, particularly in children under two years old.
Area of Science:
- Pediatric critical care medicine
- Clinical nutrition
- Nutritional epidemiology
Background:
- Nutritional status is a critical factor in pediatric patient outcomes.
- Malnutrition can complicate recovery in critically ill children.
- Early nutritional assessment is vital for effective treatment.
Purpose of the Study:
- To evaluate the prevalence of malnutrition in pediatric intensive care unit (PICU) admissions.
- To identify specific nutrient deficiencies in critically ill children.
- To explore the relationship between age and nutritional status in this population.
Main Methods:
- Nutritional status was assessed in 50 pediatric ICU admissions within 48 hours of arrival.
- Assessment included anthropometric measurements: weight-for-length, length-for-age, triceps skinfold thickness, and midarm muscle circumference.
- Patients with chronic organ failure or malignancies were excluded.
Main Results:
- 16% of patients presented with acute protein-energy malnutrition (PEM).
- 16% exhibited chronic PEM, while 18% and 20% had deficiencies in fat and somatic protein stores, respectively.
- Acute PEM and depleted somatic protein were significantly more common in children under two years old (p < 0.05).
Conclusions:
- Malnutrition and nutrient store depletion are prevalent early in pediatric critical illness.
- Younger children (< 2 years) are particularly vulnerable to malnutrition and protein depletion.
- Further research is needed to determine causality between illness severity and nutritional status.
Abstract:
Nutritional status was evaluated in 50 medical admissions to a pediatric ICU. All patients were evaluated within 48 h of admission; none had chronic organ failure or malignancies. Nutritional assessment included weight/50th percentile weight for length, length/50th percentile length for age, triceps skinfold thickness, and midarm muscle circumference. Acute protein-energy malnutrition (PEM) occurred in 16% of all children. Chronic PEM also occurred in 16%. The nutrient stores of fat and somatic protein were deficient in 18 and 20% of all children. Acute PEM and deficient somatic protein stores were more frequent in children less than 2 years (p less than 0.05). These findings indicate that malnutrition and nutrient store deficiencies are common early in the course of critical illnesses in children, especially in those less than 2 years of age. However, the findings do not indicate if the severity of illness was the cause or effect of poor nutritional status.
