人工关节置换手术部位感染发病率及危险因素分析

Analysis of incidence and risk factors of surgical site infection in patients with artificial joint replacement

目的分析人工关节置换手术部位发生感染的危险因素,为制定预防控制医院手术部位感染的策略提供依据。方法采用前瞻性调查方法,对在2011年8月至2012年3月期间医院人工关节置换手术患者进行手术部位感染目标性监测,并对发生医院感染的危险因素进行统计分析。结果共监测人工关节置换手术患者202例,发生术后感染9例,感染率为4.46%;住院天数、糖尿病、肥胖、吸烟、长期大量饮酒、手术持续时间及术后低体温是手术部位感染的危险因素。结论开展手术部位感染目标性监测能够及时掌握术后感染的危险因素,针对该类手术患者基础性疾病和不良生活习惯,做好术中和术后护理可以有效减少手术部位感染的发生。实施目标性监测,采取有效防控措施,可降低人工关节置换术后感染的发生。

Objective To analyze the risk factors for surgical site infection in patients with artificial joint replacement,so as to formulate strategy that providing basis for the prevention and treatment of surgical site infection. Methods Prospective investigation method was adopted in August 2011 to March 2012 in hospital patients with artificial joint replacement surgery for surgical site infection monitoring and the hospital infection risk factors were statistically analyzed. Results 202 cases with monitoring of artificial joint replacement surgery were monitored in this survey,and 9 cases of postoperative infection occurred with the infection rate of 4. 46%. Hospitalization days,diabetes,obesity,smoking,long-term heavy drinking,duration of surgery and postoperative hypothermia were risk factors for surgical site infection. Conclusion Implementation of targeted monitoring and infection control measures can effectively reduce the incidence of infection artificial joint replacement.
