Abstract:Objective To investigate the independent risk factors of central nervous system infection in patients with invasive intracranial pressure monitoring. Methods From January 2016 to March 2017, 60 cases of patients having invasive intracranial pressure monitoring were treated in our hospital, including 16 patients with central nervous system infection (infection group). Basic information, surgical condtion and postoperative complications of the patients were collected through questionnaire survey. Multivariate logistic regression analysis was used to analyze the independent risk factors of central nervous system infection in the patients with invasive intracranial pressure monitoring. Results There was no significant difference in age, gender, emergency surgery, electrolytes, glucose, type of disease, operative time or GCS score between the infection group and the non-infection group (P > 0.05). The drainage tube position, drainage tube indwelling time, probe position, probe retention time and complications were statistically different between the two groups (P < 0.05). Multivariate logistic regression analysis showed that the position of the probe was the protective factor of central nervous system infection during invasive intracranial pressure monitoring [Ol ^ R = 0.101 (95% CI: 0.003,1.246)], while complications were the risk factors [Ol ^ R = 5.894 (95% CI: 1.256, 6.775)]. Conclusions Probe position and complications were independent risk factors of central nervous system infection during invasive detection of intracranial pressure.
