Retrospective Study And Influencing Factors Analysis Of Surgical Site Infection In Neurosurgery

ObjectiveThe clinical features and influencing factors of Surgical site infection(SSI)in our hospital were retrospectively analyzed.Infection prevention and control measures were put forward for infection characteristics and susceptibility factors to reduce the incidence of SSI and promote the recovery of patients.MethodAfter consulting the literature,through the analysis of literature data and clinical features,SSI related research factors were extracted and information collection forms were produced.We retrospectively analyzed the clinical data of patients undergoing neurosurgery from January to December 2016 in our hospital,and reviewed the medical records of the patients through the hospital electronic medical record system and the Madison Anesthesia Information System.The information of the patients included general information of patients and intraoperative The status,SSI status,etc.are entered in the excel form,and after finishing analysis,the SPSS21.0 statistical software is used for data processing.Result1.There were 60 patients with SSI in 580 neurosurgical craniocerebral operations.The infection rate was 10.34%.Among them,there were 10 surgical incision infections(including shallow incision tissue infection and deep incision tissue infection).The infection rate was 1.72%,Intracranial infection in 51 cases(ie,organ/cavity infection),the infection rate was 8.79%,1 case of incision infection and intracranial infection.2.Univariate analysis showed that preoperative diabetes mellitus,emergency surgery,indwelling ventricle drainage tube,operative time>4h,preoperative hospital stay?7d,intraoperative blood loss>400ml,reoperation,blood transfusion,under the follicle tumor after the skull Fossa approaches and surgical incision types are potential risk factors for SSI.3.Multivariate logistic regression analysis showed that emergency surgery,preoperative hospitalization date>7d,intraoperative blood loss>400ml,duration of surgery>4h,indwelling ventricle drainage tube,subcarinal tumor surgery via posterior fossa approach is neurosurgery SSI Independent risk factors occurred.4.There was no significant difference in the impact of neurosurgery SSI between the two cleanliness grades(grades ? and ?)in the surgery(P>0.05).Conclusion1.The incidence of neurosurgery SSI is high,mainly in intracranial infections.Intracranial infection is a serious complication after neurosurgery,affecting the prognosis of patients and even life-threatening.Medical personnel should strengthen prevention and control measures and actively respond to it.At the same time,it is necessary to set up a special neurosurgery SSI monitoring department for early detection,early diagnosis,and early treatment to minimize the occurrence of SSI and minimize the impact of SSI on patients..2.There are many factors affecting neurosurgery SSI,including emergency surgery,intraoperative blood loss>400m,duration of surgery?4h,preoperative hospital stay>7d,indwelling ventricle drainage tube,submucosal tumor via posterior fossa approach 6 The major factor is the independent risk factor for SSI.Should strengthen the close cooperation of the surgical team and various disciplines,strengthen the effective communication of medical personnel,strengthen the comprehensive prevention and control measures such as the management of emergency surgery,shorten the preoperative hospital stay and the operation time;At the same time,the operation should be strictly sterile,reduce bleeding Careful indwelling ventriculous drainage tube,patients with indwelling ventricles should strengthen postoperative care and strive to remove the ventricular drainage tube as soon as possible to reduce the occurrence of SSI.3.There are no direct correlations between SSIs in neurosurgery brain surgery between two different cleanliness levels(grades I and II).
