颅脑手术部位感染率及危险因素前瞻性研究

Incidence and risk factors for neurosurgical site infection after craniotomy: a prospective study

目的研究颅脑手术部位感染率及危险因素。方法采用前瞻性方法调查我院颅脑手术病人478例。结果我院颅脑手术部位感染率为3.1%;按美国疾控中心NNIS系统SSI危险因素评分分层得到的感染率分别是:0分者1.2%(4/344),1分者7.4%(9/121),2-3分者15.4%(2/13)。发生SSI的危险因素包括手术时间>4h、术后使用引流管、SSI危险因素评分>0分、本次手术前曾进行过颅脑手术。结论我院颅脑手术SSI发生率为3.1%;危险因素为手术时间>4h、术后使用引流管、SSI危险因素评分>0分、本次手术前曾进行过颅脑手术。

Objective Investigating the incidence and risk factors for surgical site infection （SSI） after craniotomy. Methods During a 13 months period each patient undergoing craniotomy in PUMCH was prospectively investigated for the episode and risk factors of SSI. Results Among the total 478 patients, 15 patients （3, 1% ） with SSI were observed. Incidence for risk categories 0 was 1.2% , incidence for risk categories 1 was 7.4% ,incidence for categories 2 and 3 together was 15.4%. Risk factors for SSI included operation time longer than 4 hours, external CSF drainage, risk categories 〉 0, and not the patient＇s first time of craniotomy. Conclusion Among the total 478 patients, 15 patients （3. 1% ） with SSI were observed. Risk factors for SSI included operation time longer than 4 hours, external CSF drainage, risk categories 〉0 and not the patient＇s first time of craniotomy.
