Analysis of risk factors of 70 patients with intracranial infection after cranial surgery

Objective To explore the risk factors associated with craniotomy intracranial infection,providing references for clinical prevention and control of intracranial infection.Methods A total of 1356 patients that underwent cranial surgery were chosen,and the rate and the risk factors of intracranial infection were analyzed.Results ① There were 70 infection cases,the infection rate being 5.16%.Univariate analysis showed that the rates of hot season,senility,pollution surgery,prolonged surgery(≥4 h),two plus operations in a short term,postoperative cerebrospinal fluid leakage,prolonged ventricular drainage,emergency surgery were higher in the observation group than in the control group(P0.05).② Multivariate Logistic analysis showed that prolonged surgery(≥4 h),two plus operations in a short term,postoperative cerebrospinal fluid leakage,prolonged ventricular drainage were risk factors of craniotomy intracranial infection.Conclusion Long time surgery(≥4 h),two plus operations in a short term,postoperative cerebrospinal fluid leakage,prolonged ventricular drainage are craniotomy intracranial infection risk factors.Positive countermeasures should be taken in clinical practice.
