外科切口感染危险因素研究

目的：研究术后切口感染危险因素，以降低切口感染率。方法：以１９９４～１９９６年外科手术病人为对象，进行病例对照研究。结果：病例组１３１例切口感染病人和对照组１００例无切口感染病人在手术持续时间、术前抗生素使用种类、免疫抑制剂应用与否以及手术后抗生素使用天数等方面有显著性差异。且随着手术时间延长，术后切口感染的相对危险度呈明显递增趋势。结论：为降低术后切口感染率，必须尽量缩短手术时间，并减少术前术后抗生素使用天数和种类

Study of Risk Factors on the Surgery Wound Infections

Objective:In order to reduce the infection rates of surgery wounds,risk factors dealing with wound infections were investigated.Method:A case-control study was applied with the patients who had surgery operation from Jan. 1994 to Dec. 1996.There are 131 patients in case group(wounds infected) and 100 patients in control group(no wound infections).Result:There are significant differences( P <0.01) between two groups in operative hours,antibiotic sorts used pre-operation antibiotic and immunity inhibitors used or not while in hospital,and the days are spent in using antibiotic after operations.With the operation hours extending,the relative risk of wounds to be infected is increasing progressively.Conclusion:Cutting down the operative hours,the sorts and the days of antibiotics to be used before and after operations are all important for the reducing of surgery wound infections.
