Figure 4. Protein C depletion is associated with an increased incidence of nosocomial lung infection in trauma patients.

Figure 4

Patients were divided in three groups based on changes in plasma levels of protein C during the first 24h after trauma. In one group of patients there was a significant increase in the plasma levels of protein C zymogen within 12 hours after trauma. The rest of the patients who had a decrease in the plasma levels of proten C zymogen were divided into two groups characterized either by a moderate decrease of plasma levels of PC with recovery or by a significant decrease in plasma levels of PC without recovery during the first 24 hours after trauma. Patients who decreased their plasma levels of PC without any recovery had a 2.7 times increase in nosocomial lung infection than those we show some recovery of the plasma levels of PC between 12 and 24 hours after trauma (OR 2.7 CI 1.05 −6.8 p = .04).
