目的探讨结直肠肿瘤患者术后感染的危险因素,为预防治疗结直肠肿瘤术后感染提供依据。方法回顾性分析2008年1月-2012年12月行结直肠肿瘤切除术的397例患者临床资料,对患者年龄、体质量指数(BMI)、基础疾病、手术情况、放置引流管及引流管护理等相关因素进行分析,采用SPSS16.0统计软件对患者出现术后感染的例数进行t检验和χ2检验,探究影响结直肠肿瘤术后感染的危险因素及预防措施。结果年龄≥55岁、BMI≥23kg/m2、合并糖尿病、手术时间长、引流管放置时间长等因素医院感染率高,分别为18.2%、16.7%、27.5%、16.5%、16.7%,与相应组比较,差异有统计学意义(P<0.05);397例结直肠肿瘤患者手术后切口感染共检出51株病原菌,主要以革兰阴性菌为主占64.7%,其中产超广谱β-内酰胺酶菌>80.0%。结论结直肠肿瘤患者术后发生感染的危险因素多,对其进行评估,有利于提高手术效果和患者生活质量。
Objective To investigate the risk factors of postoperative infection in colorectal cancer patients and provide evidence for prevention and treatment of colorectal cancer postoperative infection. Methods The clinical data of 397 patients undergoing colorectal tumor resection from January 2008 to December 2012 were retrospectively analyzed. The patient’s age, body mass index (BMI), underlying disease, operation status, placement of drainage tubes, and drainage tube care were analyzed. Analyze other relevant factors and use SPSS16.0 statistical software to perform t-test and χ2 test on the number of patients with postoperative infections to explore the risk factors and preventive measures affecting postoperative infection of colorectal cancer. Results The age of ≥55 years old, BMI ≥23kg/m2, diabetes mellitus, long operation time, long drainage tube placement and other factors were high in nosocomial infection rate, 18.2%, 16.7%, 27.5%, 16.5%, 16.7%, respectively. There was a statistically significant difference between the two groups (P<0.05). A total of 51 pathogenic bacteria were detected in 397 cases of colorectal cancer patients after surgical incision infection. Gram-negative bacteria accounted for 64.7% of the total, which produced extended-spectrum beta- Lactamases> 80.0%. Conclusion There are many risk factors for postoperative infection in colorectal cancer patients. Evaluation of these factors will help improve the outcome of surgery and quality of life of patients.
