胃癌术后发生医院感染相关因素分析及控制对策

目的 研究胃癌术后发生医院感染相关因素分析及控制对策.方法 分析医院2007年1月-2011年12月609例胃癌术后患者,分别观察其术后发生医院感染与性别、年龄、营养状态、平均住院日、血电解质及白细胞数、术前抗菌药物治疗、术前输血、手术范围、病理类型的关系.结果 胃癌患者术后发生医院感染以肺炎、伤口感染最多,分别占42.71％、21.87％；胃癌术后医院感染与年龄、平均住院日、电解质、营养状态、白细胞水平、术前抗菌、术前输血、手术范围有关,差异有统计学意义(P＜0.05),与性别和病理类型无关.结论 通过纠正血白细胞水平及电解质紊乱、加强术后营养、提高术前预防抗菌治疗、减少术前输血等措施可以减少医院感染的发生.

Related factors and control countermeasures for nosocomial infections after gastric carcinoma surgery

OBJECTIVE To study the factors and control countermeasures of nosocomial infections after gastric carcinoma surgeries.METHODS From Jan 2007 to Dec 2011,a total of 609 patients with gastric carcinoma were selected and analyzed,the correlation between the incidence of nosocomial infections and the gender,age,nutritional status,average hospital stay,electrolytes,blood leukocyte count,preoperative antimicrobial treatment,preoperative blood transfusion,scope of surgery,and pathological types was observed.RESULTS The gastric carcinoma patients with pneumonia and the patients with wound infections accounted for 42.71% and 21.78%,respectively.The incidence of nosocomial infections was related to the age,average length of stay,electrolytes,nutritional status,blood leukocyte count,preoperative antimicrobial treatment,preoperative blood transfusion,and the scope of surgery,the difference was statistically significant(P<0.05),it was negatively correlated with the pathological types.CONCLUSION The incidence of nosocomial infections could be reduced by correcting the level of white blood cells and the electrolyte imbalance,strengthening postoperative nutrition,improving the prevention of preoperative antimicrobial treatment,and decreasing the preoperative blood transfusion.
