目的探讨引发甲状腺手术患者手术部位感染的危险因素，以期有效控制感染的发生和提高患者的生存质量。方法回顾性分析2010年1月-2013年1月普外科收治的100例甲状腺手术患者临床资料，采用logistic回归分析对相关因素进行统计分析，观察各因素与手术感染的相关性。结罘100例患者感染24例，感染率为24．0％，感染患者中年龄〉50岁的患者16例，占66．7％，手术时间〉120min的患者18例，占39，1％。有基础疾病患者20例占40．0％，切口长度≥10cm的患者17例占31．5％，Ⅲ类切口15例占37.5％;经logistic回归分析显示，手术切口的类型（OR=2．469，95％CI=I．41I～4．320）、年龄（OR=2．013，95％CI=1．095～3．701）、切口长度（OR=2．834，95％CI=1．563～5．138）、手术时间（OR=4．587，95％CI=1．65～12.691）、基础疾病（OR=5．697，95％CI=1．73～18．761）与手术部位感染具有相关因素（P〈0．05），而性别与手术部位感染无关（P〉0．05）。结论不断提高医务人员的预防意识和操作技术水平，严格无菌技术操作，合理应用抗菌药物有利于预防和降低甲状腺术后手术部位感染。

英文摘要：

OBJECTIVE To explore the risk factors for the surgical site infections in patients undergoing thyroidectomy so as to effectively control the infections and improve the life quality of the patients, METHODS The clinical data of 100 patients who underwent thyroidectomy in the general surgery department from Jan 2010 to Jan 2013 were retrospectively analyzed, then the logistic regression analysts was performed for the related factors, and the correlation between the related factors and the incidence of surgical site infections wan observed, RESULTS Of totally 100 cases of patients, the infections occurred in 24 cases with the infection rate of 84, 0%, among which there were 16 （26.7 % ） cases with more than 50 years of age, 18 （39.1% ） cases with operation duration more than 120 rain, 20 （40.0 % ） cases with underlying diseases, 17 （31.5%） cases with ,length of incision more than 10 cm, and 15 （37.5%） cases with type III incision infections. The logistic regression analysis indicated that the type of surgicalincision（OR=2.469,95% CI=1.411-4.320）, age （OR= 2. 013,95% CI=1,095-3,701）, length of surgical incision （OR = 2. 834,95% CI = 1. 563- 5. 138）, operation duration （OR=4, 587, 95% CI = 1.65- 12.691）, and underlying disease （OR=5. 697,95% CI= 1.73-18. 761） were the related factors for the surgical site infections（P〈0.05）, and the gender and surgical site were not the risk factors for the surgical site infection（P〉0. 05）. CONCLUSION To improve the awareness of prevention and the operation skills of the medical staff, strictly implement the aseptic operation, and reasonably use antibiotics may contribute to the prevention of surgical site infections after the thyroidectomy.
