With use of a quantitative limulus assay, the levels of circulating endotoxins were examined in a population of burn patients with injuries covering 1% to 88% of the total body surface area (TBSA). In cases in which the injury was less than 20% TBSA, the increases in endotoxins were only 35% as compared with those of normal controls. ⋯ Time-course studies indicated that in most cases, peak endotoxin levels occurred 3 to 4 days after injury. The data also showed that there was no relationship between the age of the patient and the extent of the endotoxin increase.
