Related risk factors for intracranial infeion after craniotomy

Objective To investigate the risk factors related to the intracranial infection after craniotomy and provide reference for the clinical prevention and control of intracranial infection.Methods Forty-six patients with craniotomy were divided into infection group(n=16)and non-infection group(n=30)according to whether intracranial infection,then the clinical data of the patients were analyzed retrospectively.Results Univariate analysis results showed that the time of operation to onset,hospitalization time,operative approach,operation time and the technical level of operators were related to the intracranial infection after craniotomy(P0.05);but the age,sex,basic disease,admitting diagnosis and craniocerebral operations times were not related to the intracranial infection after craniotomy(P0.05).Logistic regression analysis showed that the operation time exceed 3 hours,technical level of operators and operative approach were the independent risk factors for intracranial infection after craniotomy(P0.05).Conclusion The operation time,technical level of operators and operative approach are the high risk factors for intracranial infection after craniotomy.The key to reduce the intracranial infection after craniotomy is improving the technical level of operators,shortened the operation time and choosing the correct operative approach.
