We determined the effect of a body burn on pulmonary function. Full-thickness burns varying in size from 25 to 70% of total body surface (TBS), were produced in sheep. Resuscitation was performed with lactated Ringer's. We noted an increase in lung transvascular fluid flux as measured by lymph flow, Q1, during the resuscitation period, varying from one- to threefold over baseline with the degree of increase directly proportional to the burn size. The increase in QL could be totally explained by the degree of hypoproteinemia which was also proportional to burn size. Transient pulmonary hypertension 20 +/- 4 to 26 +/- 5 mm Hg and a decrease in PaO2 from 90 +/- 5 to 83 +/- 6 torr occurred in the 50 and 70% burns as well as a significant decrease in lung compliance. These alterations were not due to pulmonary edema as there was no increase in measured lung water. Also, the increase in QL could be prevented by using a combination of Dextran and protein for resuscitation but this had no effect on the hypertension or hypoxia. Burn lymph and venous plasma thromboxane levels were increased during this period of lung dysfunction. Ibuprofen 12.5 mg/kg preburn and 12.5 mg/kg every 2 hours postburn decreased the degree of dysfunction suggesting a cause and effect relationship.

The effect of a colloid (dextran-70) infusion on increased microvascular fluid and protein flux after thermal injury was compared with that seen with a crystalloid infusion. Lymph flow (QL) and lymph/phasma (L/P) protein content were used to monitor microvascular fluid flux and protein permeability in the lung and in burned and nonburned soft tissues, namely, skin and subcutaneous tissue, for 72 h in 13 sheep given a 30% TBS full-thickness burn. Vascular pressures were maintained constant with dextran in saline or lactated Ringer's. Mean fluid requirements for dextran were one-half that for crystalloid during the 24-h resuscitation period. However, plasma proteins decreased by 50% with dextran compared to 30% with crystalloid. An increase of 2-2.5 fold in QL was seen during resuscitation in the lung and nonburned soft tissue with crystalloid while the L/P protein ratio decreased, indicating no change in protein permeability. This QL response was prevented during dextran infusion. A rebound increase in soft tissue QL occurred after discontinuation of dextran, probably as a result of the severe residual hypoproteinemia. Burn QL and L/P were markedly increased during the entire 72-h period, indicating increased permeability. Dextran infusion accentuated the QL response in the burn microcirculation. We conclude that dextran decreases edema in nonburned tissue, but appears to increase the protein loss from burn tissue.
