Head trauma and leucocytosis

Abstract
A prospective analysis of 153 cases of head trauma was conducted with respect to their white blood cell counts. A white blood cell count exceeding 20×106/l is associated with a poor clinical grade on admission and with a 96% mortality as opposed to that of a 23% mortality for those with slightly lower or slightly above normal white blood cell count. The sensitivity for this level is a mortality of 96% while the specificity is 77%.
