Age-related limitations of physiologic reserve in burned children make adequacy of intravenous fluid resuscitation critical. To quantify fluid requirements, the medical records of all children admitted to the Army Institute of Surgical Research from 1980 to 1986 whose weight was 25 kilograms or less and burn size was 25% or greater were reviewed to quantify fluid requirementsForty-three children ranging in age from 1.5—108 months (&OV0335; 26 ± 22 m), with 25–89% total body surface burned (TBSB) (&OV0335; 41.7% ± 14.6%), met inclusion criteria. The average total volume of fluid received during the first 24 hours was 6.3 ± 2.2 cc/kg/% TBSB. The net volume of resuscitation fluid, total volume less the calculated maintenance fluid requirements, was 3.91 ± 2.2 cc/kg/% TBSB.Univariate analysis and linear regression of independent variables including age, weight, per cent full thickness, and inhalation injury revealed each had no significant influence on the volume of resuscitation.We recommend supplying maintenance volume and initiating burn resuscitation at 3 cc/kg/% TBSB.
