5例神经外科患者手术部位感染原因分析

目的：探讨引起短期多例神经外科患者手术部位感染的可能原因。方法：回顾2013年2月1日至3月15日所有神经外科手术患者资料，进行相关暴露因素分析，探讨可能引起手术部位感染的危险因素。结果：“第五手术间”OR=4．07（95％CI=0．52～36．65），第五手术间环境微生物采样除麻醉剂袖带菌落总数超标以外均符合国家要求；各“手术主刀医生”“手术参与者”的手术部位感染专率较神经外科手术部位平均感染率均无差异（P〉0．05）；“二次手术”OR=18．00（95％CI=2．00～180．00）。结论：“二次手术”是此次短期多例神经外科患者手术部位感染的高危因素；对其干预措施可由此入手，进一步探讨。

The causes analysis of surgical site infection in 5 neurosurgical patients

Objective： To investigate the possible causes of surgical site infection （SSI） in neurosurgical patients. Methods： Reviewed all the neurosurgical patients＇ data from February 1 to March 15, 2013, and conducted a case-control study to analyze the possible SSI＇s risk factors. Results： ＂The fifth operating room＂ OR=4.07 （95% CI=0.52-36.65）. The environmental microbiological samples of the fifth operating room consisted with national requirements except anesthetic cuff. Each ＂surgery surgeon＂ and each ＂surgical participant ＂special surgical site infection rates were not significant different （P〉0.05） respectively compared with the average neurological surgical site infection rate. ＂The second surgery＂ OR=18.00 （95% CI=2.00-180.00）. Conclusion： ＂The second surgery＂ was the key risk factor for SSI of neurosurgical patients. Thus the interventions could be started to explore further.
