Evaluation on the risk factors of progressive hemorrhagic injury after acute traumatic brain injury

Objective To evaluated the independent risk factors of the occurrence of progressive hemorrhagic injury after acute traumatic brain injury.Methods 274 cases of traumatic brain injury patients admitted in our hospital were retrospectively analyzed.The 86 cases with progressive hemorrhagic injury were included in progressive group.The other 188 cases were included in non-progressive group.The incidence of progressive hemorrhagic injury was calculated.Results The age,gender,GCS score when admitted in hospital,mydriasis,mean arterial pressure,skull fracture,epidural hematoma,cerebral contusion,bilateral injury,subarachnoid hemorrhage,volume of hematoma at the first CT scanning time,the change of cerebral heatoma influence the development of progressive hemorrhagic injury(P0.05).GCS score less than 12,mydriasis,cerebral contusion,subarachnoid hemorrhage and volume of hematoma more than 10 ml at the first CT scanning are the independent risk factors of the progressive hemorrhagic injury after traumatic brain injury.Conclusion GCS score less than 12,mydriasis,cerebral contusion,subarachnoid hemorrhage and volume of hematoma more than 10 ml at the first CT scanning are the independent risk factors of the progressive hemorrhagic injury after traumatic brain injury.Early repeated CT scanning contributed to early diagnosis of progressive hemorrhagic injury and improve the outcome.
