胃肠外科手术患者感染的因素分析及预防对策

Analysis of factors for gastrointestinal surgical infections and preventive measures

目的探讨胃肠外科手术感染的相关性因素及其预防对策,为预防临床感染提供依据。方法调查2012年1月-2013年4月在医院行胃肠外科手术1 200例患者临床资料,分析发生感染因素与病原菌分布,数据采用SPSS16.0进行统计处理。结果共64例患者手术后发生感染,感染率为5.33%;手术感染与手术目的、手术类型、切口类型、年龄、手术时间及出院时间呈明显相关性,比较差异有统计学意义(P<0.05);共检出124株病原菌,以革兰阴性菌为主,共76株占61.29%。结论胃肠外科手术患者应严格控制其手术环境,加强手术前后护理,配合抗菌药物的使用,帮助患者早日康复。

OBJECTIVE To investigate the factors for gastrointestinal surgical infections and its preventive meas‐ures ,so as to provide reference for prevention of clinical infections. METHODS The clinical data of 1200 patients undergoing gastrointestinal surgery in our hospital during Jan. 2012 to Apr. 2013 were investigated. The infective factors and the distribution of pathogens were analyzed. The software SPSS16. 0 was used for statistical analysis. RESULTS Totally 64 patients had surgical infections ,the infection rate was 5. 33%. The surgical infection was significantly correlated with the purposes of surgery ,the types of surgery ,the types of surgical incision ,age ,op‐eration time and discharge time ,the difference was statistically significant （P＆lt;0. 05）. There were 124 pathogens for surgical infections ,mostly gram‐negative bacteria ,accounting for 61. 29% （76 strains）. CONCLUSION For gastrointestinal surgical patients ,clinicians should strictly control their surgical environment ,strengthen the nurs‐ing care before and after surgery in combination with the use of antimicrobial drugs to help patients recover soon.
