Plasma fibronectin concentrations in patients with severe burn injury.

Plasma fibronectin concentrations were measured in 33 patients with major burn injury. Changes in plasma fibronectin concentration were related to the day of burn injury, surgery and to the development of sepsis. Within 24 hours of the burn injury and surgical treatment, a decrease of the plasma fibronectin concentration was observed, which returned to normal values within 72 hours. A decrease in the plasma fibronectin concentration was observed as sepsis developed, while recovery from septicaemia was associated with plasma fibronectin concentration returning to normal values.
