Our purpose was, in general, to determine the effect of a body burn on the pulmonary response to endotoxemia and, specifically, to determine whether increased thromboxane (TxA2) production by the burn wound was responsible for the accentuated lung injury. Thirty-two unanesthetized sheep with lung and soft tissue lymph fistulae were studied. Twelve sheep were given a sublethal dose of intravenous E. coli endotoxin (2 micrograms/kg). A characteristic two-phase injury was noted as evidenced by early pulmonary hypertension and hypoxia and later increased lung permeability. TxA2 was significantly increased in lung lymph as well as aortic plasma relative to venous plasma, indicating the lung to be the source. Twelve of 12 sheep survived. Five of 13 sheep died from endotoxemia when given 3-5 days after a 25% total body surface (TBS) burn and five of seven died with endotoxin (2 micrograms/kg) and a 50% burn. Physiologic parameters were at preburn levels before endotoxin. Animals died both during the early phase from hypoxia and the later phase due, in large part, to increasing pulmonary dysfunction. Absolute levels of TxA2 were not increased in the postburn animals, nor was there a clear release of TxA2 from burn tissue to explain the accentuated response. Prostacyclin levels were, however, less elevated in postburn animals in response to endotoxin, thereby altering the TxA2/PGI2 ratio in favor of TxA2. However, a cause and effect relationship between the increased lung injury and TxA2 remains undetermined. Lymph flow or lymph protein content was not altered in burn tissue in response to endotoxin.
