[Determination of blood endotoxin in severely burned patients and its clinical significance].
Since October 1985 to June 1987, in 12 severely burned patients with endotoxemia was observed by using a quantitative endotoxin assay of limulus amoebocyte lysate (LAL) test with a chromogenic substrate. Among the 12 patients, 4 died and 8 survived. The average age of dead group was 31.8 years (19-45 years), mean TBSA was 63% (58-80%) and mean I 18.5%. The survival group average age of survival group was 27.5 years (18-39 years), mean TBSA was 58% (18-85%) and mean I 24.4% (6-56%). The plasma endotoxin concentrations of burn patients in dead group were 105-571 pg/ml, significantly higher than that of survival group (30-240 pg/ml) and healthy human (6.44 +/- 1.96 pg/ml). It was found that the increase of endotoxemia was closely related to burn wound sepsis, positive of blood culture, systemic disseminated septicaemia. Systemic use of sensitive antibiotics may increase the level of blood endotoxin in severe gram-negative bacillus infection. Polymixin-B is an exception.
