Insights
Infants with pulmonary insufficiency may experience growth failure due to high energy expenditure. The doubly labeled water technique confirms increased energy needs in infants with chronic lung disease and other critical conditions.
Area of Science:
- Pediatric Medicine
- Neonatology
- Physiology
Background:
- Growth failure in infants is often linked to high energy expenditure.
- Indirect calorimetry has provided inconsistent results for assessing infant energy expenditure.
- Newer techniques are needed to accurately measure energy expenditure in infants.
Purpose of the Study:
- To evaluate the utility of the doubly labeled water technique in assessing energy expenditure in infants.
- To investigate the relationship between pulmonary insufficiency and energy expenditure in infants.
Main Methods:
- Utilized the doubly labeled water technique to measure energy expenditure.
- Compared energy expenditure in infants with various clinical conditions, including pulmonary insufficiency, chronic lung disease, and congenital heart disease.
- Included extremely low birth weight infants and minimally ill infants.
Main Results:
- The doubly labeled water technique provided evidence for increased energy expenditure in infants with chronic lung disease and congenital heart disease.
- Elevated energy expenditure was also observed in minimally ill, extremely low birth weight infants.
- This technique shows promise for studying energy expenditure in diverse infant populations.
Conclusions:
- The doubly labeled water technique is a valuable tool for accurately assessing energy expenditure in infants.
- Increased energy expenditure is a significant factor contributing to growth failure in infants with pulmonary insufficiency and other critical conditions.
- Further research using this method can elucidate energy metabolism in various pediatric clinical settings.
Abstract:
The observed growth failure in infants with pulmonary insufficiency is postulated to be a consequence of elevated rates of energy expenditure. Assessment of energy expenditure by the classical technique of indirect calorimetry has yielded conflicting results. The adoption of the newer, doubly labeled water technique has provided evidence to support increased rates of energy expenditure in infants with chronic lung disease, congenital heart disease and in minimally ill, extremely low birth weight infants. The doubly labeled water technique holds great promise for the detailed study of energy expenditure in a variety of clinical conditions, including very ill as well as free-living subjects.
