Multi-factor analysis of the central nervous system infection after invasive intracranial pressure monitoring / 中华神经科杂志

ABSTRACT

Objective To investigate the related factors of central nervous system infection in patients who received invasive intracranial pressure monitoring.Methods The clinical data of 63 patients who received invasive intracranial pressure monitoring were retrospectively analyzed.Possible related factors including gender,age,disease,Glasgow coma scale score,emergency operation or selective operation,duration of the operation,drainage tube placement site,drainage tube lifetime,sensor insertion site,sensor indwelling duration,electrolytes,glucose and other complications were studied and compared retrospectively between patients with and without central nervous system infection.All data were analyzed with univariate analysis and multivariate Logistic regression analysis to identify the related factors and independent risk factors associated with central nervous system infection.Results In univariate analysis,drainage tube placement site (x2 =12.345,P =0.002),drainage tube lifetime ((2.5 ± 0.9) d and (6.3 ± 5.7) d in patients without and with central nervous system infection,respectively,t =-4.434,P =0.000),sensor insertion site (x2 =4.701,P =0.030),sensor indwelling duration ((6.5 ± 3.0) d and (8.9 ± 4.6) d in patients without and with central nervous system infection,respectively,t =-2.420,P =0.019) and other complications (x2 =13.086,P =0.000) were the relevant factors of central nervous system infection (P ＜0.05).In multivariate Logistic regression analysis,the sensor insertion site (OR =0.047,P =0.000) and other complications (OR =10.953,P =0.019) were the independent risk factors for the central nervous system infection.Conclusions There are a variety of factors related to central nervous system infection in patients with placement of intracranial pressure monitoring.The sensor insertion site and other complications were the independent risk factors for the central nervous system infection.
