RELATIONSHIP BETWEEN BRAIN CT SCAN FINDINGS WITH EPIDEMIOLOGY OF TRAUMATIC INTRACRANIAL HEMORRHAGE, CHANGES IN BLOOD COAGULATION FACTORS, SURGICAL FINDINGS, LEVEL OF CONSCIOUSNESS AND FATE OF PATIENTS WITH TRAUMATIC INTRACRANIAL HEMORRHAGE

Trauma is leading cause of death among the young, adults and children, and traumatic brain injuries account for over 50%of deaths caused by trauma. Patients with traumatic brain injury should be treated based on our knowledge on the incidence rate of brain injuries caused by trauma and the symptoms after traumatic brain injury. The study population included the patients with traumatic brain injury and brain hemorrhage, which were clearly detectable and measurable in CT scan stereotypes. The study samples were selected using convenience sampling method. The collected data were encoded and inserted to the computer, then were analyzed using descriptive statistics (mean, standard deviation and confidence interval), chis-quare test and correlation coefficient test. The used software was SPSS 18. 343 out of 1835 head trauma patients admitted to Khatam-Al-Anbia Hospital, in which68cases had traumatic intracranial hemorrhage and all patients underwent surgery. In contrast to CT scan findings and based on surgical findings, the hematoma was epidural in15cases, subdural in 16cases, intraparenchymal in 13 cases, intraventricular in 15 cases and subarachnoid in 9 cases. There was a significant inverse relationship between hematoma volume and level of consciousness on admission, so that the larger sizes of the hematoma caused further drop in the level of consciousness on admission. In addition, the fate of patients with traumatic brain injury depends on the level of consciousness and hematoma volume on the CT scan is inversely related to the consciousness level of patients. According to the dependence of hematoma volume on the CT scan and consciousness level of patients, we can suggest the use of these parameters in CT scan aiming to predict the fate of these patients beside the other common parameters.
