Risk factors and prognosis of progressive intracranial hemorrhage in patients with acute traumatic brain injury / 中华创伤杂志

ABSTRACT

Objective To investigate the risk factors related to progressive intracranial hemorrhage (PIH) in patients with acute traumatic brain injury (TBI) and analyze their clinical significance.Methods PIH was validated by comparing the initial and repeated CT scans. Data including gender,age, injury causes, Glasgow Coma Score (GCS) on admission, time interval from injury to the first CT scan, initial CT scan manifestations, prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fg), thrombin time (TT), platelet (PLT) and D-dimer (D-D) in both groups were compared with Logistic regression analysis to observe the risk factors related to PIH. Results The study involved 498 patients with acute TBI, of which 139 (27.91%) patients suffered from PIH. There were 116 patients (83.45%) with PIH who received the initial CT scan within two hours post injury.There was statistical difference in aspects of age, GCS on admission, time interval from injury to the first CT scan, initial CT scan manifestations ( including fractures, subarachnoid hematoma, contusion and onset hematoma), PT, Fg and D-D values in both groups (P ＜0.01 ). Logistic regression analysis showed that CT scans (subarachnoid hemorrhage, brain contusion and primary hematoma) and plasma D-D values were predictors of PIH ( P ＜ 0.01 ). Conclusions For patients with the initial CT scan manifestations including subarachnoid hemorrhage, brain contusion, primary hematoma together with D-D value increase within two hours post injury, a continuous CT scan should be performed promptly to detect PIH early.
