ABSTRACT
Objective To explore external cerebral herniation at different times in traumatic brain injury patients after decompressive craniectomy.Methods Clinical data of 90 patients with traumatic brain injury routine hemicraniectomy were analyzed,brain incisional hernia incidence and severity in early (less than a week after surgery), medium (after 7d-30d)and late (after 1 month-June),and compare GCS score and GOS score of different periods were observed.Results Brain incisional hernia incidence in early,middle and late was 42.22%,21.11%,12.12%with significant difference(χ2 =4.312,P<0.05;χ2 =4.523,P<0.05;χ2 =4.543,P<0.05),and the severity in early was the most(P<0.01);GCS scores in early,mid and late was (3.22 ±0.41)points,(6.53 ±0.37)points, (12.05 ±0.84)points with significant difference(t=5.215,P<0.05;t=6.312,P<0.05;t=6.312,P<0.05);T test showed that the difference was existed between different period of patients.Conclusion Traumatic brain injury incidence and serivity in 1 week was the most;brain hernia occurs sooner in GCS score lower patients;prognosis was worse in later external cerebral herniation patients,so GCS score and incisional hernia occurrence time is important for improving prognosis of traumatic brain injur patients.
