title: Incidence of early burn-induced effects on liver function as reflected by the plasma disappearance rate of indocyanine green: a prospective descriptive cohort study.
abstract: Organ dysfunction and failure are important for burned patients as they increase morbidity and mortality. Recent evidence has suggested that organ injuries are occurring earlier after burns, and are more common than previously thought. In this study we have assessed the extent to which liver function, assessed by the plasma disappearance rate of indocyanine green (PDR(ICG)), is affected in patients with severe burns. This is a prospective, descriptive exploratory study at a national burn centre. Consecutive adult patients with a percent total body surface area burned (TBSA%) of 20% or more, were examined prospectively by dynamic (PDR(ICG)) and static liver function tests (plasma: bilirubin concentration, prothrombin complex, and alanine aminotransferase and alkaline phosphatase activities). Early liver dysfunction was common, as it is assessed by both dynamic (7 of 17) and static liver function tests (6-17 of 17). A regression model showed that changes in PDR(ICG) were associated with age, TBSA%, plasma bilirubin concentration, plasma C-reactive protein concentration, and cardiac index. Persistent and advanced hepatic dysfunction was associated with mortality. The PDR(ICG) seems to give a comprehensive assessment of liver function after major burns. Hepatic dysfunction seems to be as common as dysfunction in other organs. We interpret the recorded effects on liver function as part of a multiple organ dysfunction syndrome, primarily induced by the burn itself. However, this needs to be further investigated.
