Logistic regressionanalysis on the risk factors for external hydrocephalus after traumatic brain injury inthe infants and young children

Abstract

：Objective To analyze therisk factors for the external hydrocephalus (EH) after traumatic brain injury in theinfants. Methods The clinical data of 178 cases of infants and young children withtraumatic brain injury from March 2004 to April 2009 were retrospectively analyzed.Univariate and logistic regression analysis were performed to identify the clinical riskfactors for EH after traumatic brain injury. Results By univariate regression analysis,age, GCS score after trauma, coma duration, brain contusion, subarachnoid hemorrhage andepilepsy were risk factors for external hydrocephalus in the infants and young children(Ps 0. 05). The incidence of EH after traumatic brain injury in the infants and youngchildren was 14% (25/178 ). Age ( OR = 0.5743 ) , coma duration after trauma (OR =3.0628),subarachnoid hemorrhage (OR =3.7093),brain contusion(OR = 4.7892) and post-traumaepilepsy (OR =2. 9976) were risk factors for EH (Ps < 0. 05). Conclusion Younger than 2years old, low GCS score, long coma duration, brain contusion, subarachnoid hemorrhage andepilepsy would increase the risk of EH after traumatic brain injury in the infants andyoung children. This study provides information for the prevention of EH after traumaticbrain injury in the infants and young children.
