Dynamic Changes of Hemostasis in Patients with Traumatic Brain Injury Undergoing Craniotomy: Association with in-Hospital Mortality.

Background: Traumatic brain injury (TBI) induces complex systemic hemostatic alterations associated with secondary brain damage and death. We specifically investigated perioperative changes of hemostasis in patients with isolated TBI undergoing major neurosurgery and searched for their influence on outcome.

Methods: Serial analysis (four time points, T0-T3) of conventional coagulation assay and rotational thromboelastometry data acquired during 72 h from admission of 68 patients who underwent craniotomy to remove hematoma and/or to decompress the brain was performed.
