人工关节置换术后患者切口感染的调查分析

Investigation and analysis of incision infections in patients after artificial joint replacement

目的通过探讨患者自身因素与人工关节置换术后切口感染发生的相关性,从而采取措施降低术后切口感染的概率。方法对2009-2012年人工关节置换术1 622例患者的临床资料进行回顾性调查分析,以卫生部《医院感染诊断标准》为诊断标准,数据录入Excel进行统计分析。结果 1 622例患者中48例术后发生切口感染,其中深部感染29例,浅部感染19例,感染率为2.96%;感染类型以糖尿病为最高,感染率为5.32%;感染病原菌以革兰阳性菌为主,占63.64%,主要为表皮葡萄球菌,占57.14%。结论患者的自身因素对人工关节置换术后切口感染有着重要的影响,要详细了解患者的现病史和既往史,术前对患者进行干预并采取行之有效预防措施,是降低术后感染率的关键。

OBJECTIVE To investigate the correlation of patients＇ personal factors and incision infections after artificial joint replacement, so as to take measures to reduce the risk of postoperative incision infections. METHODS The clinical data of 1622 patients who received artificial joint replacement in 2009-2012 were retrospectively analyzed, taking Diagnostic Criteria for Hospital Infection issued by Minister of Health as the diagnostic criteria. Data were input in Excel for statistical analysis. RESULTS The 1 622 patients had 48 cases of postoperative incision infections, including 29 cases of deep infections and 19 cases of superficial infections, the infection rate was 2.96 %. Types of infection were mainly diabetes, its infection rate was 5.32 %. Infectious pathogen was mainly gram-posi- tive bacteria, accounting for 63.64%. The main pathogenic bacteria were Staphylococcus epidermidis, accounting for 57. 14%. CONCLUSION Personal factors have significant influence on wound infection after artificial joint replacement. To learn more about the patient＇s history and past medical history, and to perform preoperative intervention on patients and take effective preventive measures, are the keys to reduce postoperative infection rate.
