[The tolerance to exogenous energy substrates in the post aggression period in children]
Insights
Children show increased tolerance to fatty emulsions and reduced glucose tolerance after aggressive interventions like surgery or trauma. These metabolic changes are most significant in the initial three days post-aggression.
Area of Science:
- Metabolic studies
- Pediatric critical care
- Nutritional science
Context:
- Investigates the impact of aggressive interventions (surgical, trauma) on pediatric patients.
- Utilizes a prolonged glucose-fat tolerance test to assess metabolic responses.
- Examines pharmacokinetic parameters of glucose and fatty emulsion elimination.
Purpose:
- To characterize changes in glucose and fatty emulsion tolerance in children post-aggression.
- To determine the time course of altered substrate elimination.
- To understand the metabolic consequences of severe physiological stress in pediatric populations.
Summary:
- Children exhibit heightened tolerance to exogenous fatty emulsions and diminished glucose tolerance following aggressive interventions.
- These metabolic alterations are most pronounced within the first 72 hours after the aggressive event.
- The study analyzed 44 children undergoing various forms of surgical or mechanical trauma.
Impact:
- Provides insights into pediatric metabolic adaptation to critical illness and injury.
- Informs nutritional support strategies for children in the post-aggression period.
- Highlights the transient nature of these metabolic shifts, crucial for clinical management.
Abstract:
Pharmacokinetic parameters of glucose and fatty emulsion elimination from the vascular bed have been studied using prolonged glucose-fat tolerance test. Forty-four children have been examined upon various aggressive interventions. Surgical intervention or mechanical trauma have been regarded as an aggressive factor. It has been established that children in the post aggression period are characterized by a pronounced increase of exogenous fatty emulsion tolerance and a reduction of glucose tolerance. The most marked changes in the elimination of basic energy substrates are observed in the first three days after the aggression.
