颅脑手术患者手术部位感染状况及相关危险因素调查

Investigation of surgical site infection status and related risk factors in patients with craniocerebral operation

目的分析颅脑手术患者手术部位感染状况及相关危险因素。方法选取2016年1月至2019年2月在我院神经外科接受颅脑手术的患者363例为研究对象,根据是否发生手术部位感染,将其分为感染组和未感染组。对感染组患者手术部位感染状况进行调查,并采用单因素和多因素logistic回归分析确定颅脑手术患者发生手术部位感染的相关危险因素。结果363例颅脑手术患者中,发生手术部位感染的患者有9例(2.48%),其中表浅切口感染1例(11.11%),器官/腔隙感染8例(88.89%)。经多因素logistic回归分析结果显示,术前住院时间、手术时长、术区引流管留置时间、脑室外引流是颅脑手术患者发生手术部位感染的独立危险因素(P<0.05)。结论颅脑手术患者手术部位感染的影响因素众多,其中术前住院时间、手术时长、术区引流管留置时间、脑室外引流是颅脑手术患者手术部位感染的独立危险因素,因此,应结合患者的自身情况,采取具有针对性的有效措施进行预防控制,从而减少手术部位感染的发生率。

Objective To analyze the surgical site infection status and related risk factors in patients with craniocerebral operation.Methods To select 363 cases of patients who underwent cranial surgery in neurosurgery from January 2016 to February 2019 as a study object.According to whether the surgical site infection occurred,they were divided into infected group and uninfected group.The infection status of the surgical site was investigated in the infected group,and the risk factors associated with the surgical site infection in patients with craniocerebral surgery were determined by univariate?and multivariate logistic regression analysis.Results In the 363 cases of patients with craniocerebral surgery,9 cases(2.48%)had surgical site infections,including 1 case(11.11%)of superficial incision infection and 8 cases(88.89%)of organ/lacunainfection.Multivariate logistic regression analysis showed that preoperative hospitalization time,length of surgery,indwelling time of drainage tube,and external ventricular drainage were independent risk factors for surgical site infection in patients with craniocerebral surgery(P<0.05).Conclusion There were many factors influencing the surgical site infection in patients with craniocerebral operation.The preoperative hospitalization time,the length of surgery,the indwelling time of the drainage tube in the operation area,and the external ventricular drainage were independent risk factors for surgical site infection in patients with craniocerebral surgery.Therefore,they should be combined with the patient's own situation,taking targeted and effective measures for preventive control,thereby reducing the incidence of infection at the surgical site.
