The Research Of Nosocomial Infection And The Relevant Risk Factors In Patients After Craniotomy

Objective To explore the risk factors and prevention measures for thenosocomial infection after craniotomy.Methods From January2011to December2012, the clinical data of169patients after craniotomy were retrospectively analyzed. Research the relevant riskfactors of the nosocomial infection, The lungs infection, intracranial infection and theurinary infection. Using SPSS17.0statistical software for data processing, all the factorsare variable assignment, different factors according to the infection line classificationrespectively binary logistic regression analysis, obtained significant factor summarybefore the infection type line of binary logistic regression analysis respectively, B>0, P<0.05for the difference was statistically significant.Results The nosocomial infection occurred in44of169patients undergoingthe cranitomy, the incidence of nosocomial infection was26.04%(44/169); the casesrate was31.37%(53/169). The main infection site was lower respiratory tract infection,accounting for14.02%,45.29%in infection cases. Followed by intracranial infection,accounting for9.47%, the cases rate was30.19%. The next one was the urinaryinfection, accounting for4.73%, the cases rate was15.09%.The last one was the otherinfection, accounting for2.96%,the cases rate was9.43%.Different kinds factorsaccording to the infection employ classification binary logistic regression analysisshowed that diabetes, operation time,the long Intensive Care Unit stay, postoperativehospital stay, open trauma, closed trauma, catheter indwelling time, tracheotomy andtracheal intubation, long Intensive Care Unit stay and postoperative cerebrospinal fluidleakage and the unalive conditionin,to some extent, related to the several kinds ofinfection (B>0, P<0.05), can be included in the factors quadratic regression.Accordingto the types of infection, put the meaningful factors into binary logistic regressionanalysis respectively. Analysis found that: the long Intensive Care Unit stay (OR=1.155), the long urinary catheterization duration (OR=2.925), unalive condition (OR=2.736),trachea incision (OR=3.752) and continued lumbar cerebrospinal fluid drainage(OR=10.592) five indicators are independent risk factors of hospital infection occurredafter craniotomy; tracheostomy (OR=7.264) and the long Intensive Care Unit stay(OR=1.189), two factors are independent risk factors for postoperative pulmonaryinfection in craniotomy; Cerebrospinal fluid leakage (OR=29.426) and continuedlumbar cerebrospinal fluid drainage (OR=29.063) two factors are independent riskfactors of intracranial infection occurred after craniotomy; the long urinarycatheterization duration (OR=7.858) and diabetes (OR=23.586), two factors areindependent risk factors of urinary tract infections occurred after craniotomy.Conclusion Nosocomial Infectionin Patients after Craniotomy can be relatedwith a single factor or multiple factor.But the long Intensive Care Unit stay,glycuresis,the long urinary catheterization duration,tracheotomy,continued lumbarcerebrospinal fluid drainage, the cerebrospinal fluid leakage and unalive condition werethe susceptible risk factors for the patients after craniotomy.
