Hypertension in children with burns
Insights
Hypertension is common in pediatric burn patients, affecting over 30% with sustained high blood pressure. Tachycardia was the main predictor, and younger age increased risk, but survival was not impacted.
Area of Science:
- Pediatric Burn Care
- Cardiovascular Physiology
- Critical Care Medicine
Background:
- Hypertension is a frequent complication in pediatric burn survivors.
- Understanding the prevalence and risk factors for hypertension in this population is crucial for effective management.
Purpose of the Study:
- To investigate the incidence and clinical correlates of hypertension in children with burns.
- To identify factors associated with hypertension development and its impact on survival.
Main Methods:
- Retrospective analysis of pediatric patients admitted to a burn treatment center.
- Monitoring of blood pressure for sustained and episodic hypertension.
- Correlation analysis with clinical findings, demographics, and injury extent.
Main Results:
- Sustained hypertension observed in 31.5% of children; episodic hypertension in 57.4%.
- Tachycardia was the sole significant clinical correlate of hypertension.
- Hypertension prevalence was higher in younger children; no correlation with sex, race, or burn extent.
- Hypertension did not adversely affect survival rates.
Conclusions:
- Hypertension is a significant concern in pediatric burn patients, often linked to persistent tachycardia.
- Age is a key factor, while burn severity and demographics play a lesser role.
- Further research into pathogenic mechanisms like elevated catecholamines and renin is warranted.
Abstract:
Hypertension has been observed to occur frequently in children with burns. In a series of children admitted to the St. Agnes Burn Treatment Center, sustained systolic and diastolic hypertension occurred in 31.5%, and 57.4% of the children demonstrated episodic periods of hypertension which were unsustained. The only clinical finding which significantly correlated with the hypertension was the presence of tachycardia, which persisted into the late healing phase of the thermal injury. Hypertension was more prevalent at younger ages. However, there was no other correlation of the development of hypertension with sex, race, or extent of thermal injury. The development of hypertension in itself did not worsen the prognosis for survival in the cases presented in this series. Possible pathogenic mechanisms which result in hypertension (elevated catecholamines, norepinephrine, renin secretion) are discussed.
