Hypertension in children with burns.

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.
