Risk factors for intraoperative encephalocele in brain injury patients

Abstract

Objective To explore the risk factors of acute intraoperative encephalocele in craniotomy of brain injury patients.Methods Gender,age,history of hypertension,hypotension,hypoxemia,primary brainstem injury,cerebral hernia,brain edema,time from injury to surgery,skull surgery distant sites fractur and bleeding situation were recorded and analyzed in 190 patients with acute intraoperative encephalocele and 506 patients without encephalocele.Results Distant sites fractured and bleeding,brain edema,cerebral hernia,hypoxemia,primary brainstem injury,time from injury to surgery,were closely related to the acute intraoperative encephalocele(P ＜ 0.05).Conclusions Skull surgery distant sites fracture,hypoxemia,primary brainstem injury,cerebral hernia,brain edema,and surgery distant sites bleeding situation (epidural hematoma) are the risk factors for the acute intraoperative encephalocele,that the time from injury to surgery is a protective factor.Actively correct hypoxia,primary brainstem injury and prevent secondary damage,prevention of distant sites bleeding situation can effectively reduce intraoperative encephalocele.
