某院阑尾切除术手术部位感染监测

Monitoring on surgical site infections following appendectomy in a hospital

摘要:

目的了解某手术部位监测院阑尾切除术手术部位感染情况和危险因素，为采取有效的防治措施提供依据。方法通过手术部位监测方法，对2011年7月1日—2013年7月1日该院阑尾切除术患者手术部位感染情况进行调查。结果共监测患者817例，发生手术部位感染37例，感染率为4.53%，其中表浅手术切口感染36例，深部切口感染1例。单因素分析结果显示：阑尾切除术手术部位感染与手术持续时间、麻醉方式、ASA评分、血糖、围手术期是否使用抗菌药物和手术危险指数评分有关（均P＜0.05）。多因素logistic回归分析结果显示，血糖（OR 95% CI: 1.07～4.72）、围手术期是否使用抗菌药物（OR95% CI: 1.14～7.10）、危险指数评分（OR95% CI:5.90～43.28）是阑尾切除术手术部位感染的独立危险因素（均P＜0.05）。 结论手术部位监测有助于了解阑尾切除术手术部位感染危险因素；临床应采取针对性的干预措施，积极预防阑尾手术切口感染。

Abstract:

ObjectiveTo understand the occurrence and risk factors for surgical site infections (SSIs) following appendectomy, so as to provide reference for taking effective prevention measures.  MethodsThrough monitoring on surgical site, SSIs in patients undergoing appendectomy in a hospital from July 1,2011 to July 1,2013 were investigated. ResultsA total of 817 appendectomy surgery patients were investigated, 37 (4.53%) of whom had SSIs, 36 of which were superficial wound infection, and 1 was deep wound infection. Univariate  analysis  showed that SSIs were related with  duration of operation, anesthesia mode,  ASA score, blood sugar, whether perioperative antimicrobials were used, and operative risk index score（all P＜0.05）. Multivariate logistic regression analysis revealed that blood sugar （OR 95% CI: 1.07-4.72）, whether perioperative antimicrobials  were used（OR 95% CI: 1.14-7.10）, and  risk index score （OR 95% CI: 5.90-43.28）were independent  risk factors for SSIs following appendectomy (all P<0.05).ConclusionSurgical site monitoring is helpful for the understanding of SSIs following appendectomy; proper intervention measures should be adopted in clinic to prevent SSIs following appendectomy.
