某医院骨科患者手术部位感染临床分析

Analysis of the characteristics of surgical site infection of orthopedics patients in a hospital

目的研究医院骨科手术患者切口部位感染的特点,并采取相应预防措施,降低感染发生率。方法采用回顾性分析方法,对某医院骨科手术患者手术部位感染率、病原菌特点及相关因素进行分析。结果共调查该医院骨科手术患者2 821例,共发生手术部位感染34例,感染率1.21%。清洁切口、清洁-污染切口和污染切口的感染率依次分别为0.98%、1.80%和4.55%。差异有统计学意义(P<0.05)。从感染部位送检标本中检出病原菌32株,主要致病菌为凝固酶阴性球菌、金黄色葡萄球菌、大肠埃希菌和铜绿假单胞菌。手术持续时间、手术植入物、实施手术的季节等因素影响骨科手术切口感染的发生。结论骨科手术部位感染病原菌以革兰阳性菌为主,骨科手术切口感染与切口类型、手术持续时间、植入物的使用、手术季节具有相关性。应采取集束化的干预措施,控制感染率。

Objective To study the characteristics of surgical site infection of Orthopedics Patients and take corresponding preventive measures. Methods Retrospective survey was used to investigate the clinical data of orthopedics patients and analyze the characteristics of the surgical site infection rate,the distribution of pathogenic bacteria and its related factors. Results Of all the 2 821 patients,34 cases had surgical site infection and the infection rate was 1. 21%. The infection rate of clean surgery,clean- pollution surgery and pollution surgery were 0. 98%,1. 80% and 4. 55% respectively,the difference was statistically significant. 32 strains of pathogenic bacteria were detected including coagulase negative Staphylococcus aureus,Staphylococcus aureus,Enteric bacilli and Pseudomonas. Surgical duration,surgical site infection implant and surgical season influence the rate of surgical site infection. Conclusion The main pathogenic bacteria of orthopedics surgical site infection is Gram- positive bacteria,and infection rate is related to surgery type,surgical duration,use of implant and surgery season.
