[摘要] 目的 分析普外科患者术后感染发生率和影响因素,为临床防治提供参考。 方法 方便选取该院2016年9月—2019年3月普外科接受手术患者722例为研究对象,整理患者临床资料,分析术后感染发生率,术后感染患者作为观察组,未感染患者为对照组,并分析术后感染影响因素,采用Logistic回归多因素分析。 结果 722例患者中,其中22例患者发生术后感染,感染发生率为3.05%,男14例,女8例。单因素分析结果显示,年龄、性别、BMI高、手术季节、切口类型等均是术后感染危险因素(P<0.05)。观察组患者年龄、手术时间显著大于对照组(P<0.05),多因素Logistic回归结果显示糖尿病、病房条件、BMI高、ASA分级、手术危险指数是切口感染独立危险因素(P<0.05),Backward-LR后退分析年龄、糖尿病、切口分类与ASA分级存在明显相关性(P<0.05),其中糖尿病危险程度最高。 结论 普外科患者术后感染与手术危险系数以及基础疾病有关,应加强术后感染预防和控制,降低感染发生率。

[Abstract] Objective To analyze the incidence and influencing factors of postoperative infections in general surgery patients to provide references for clinical prevention and treatment. Methods 722 patients who underwent surgery in thehospital from September 2016 to March 2019 were convenient selected as the research objects. The clinical data of the patients were sorted out and the incidence of postoperative infection was analyzed. Postoperative infected patients were used as the observation group, and uninfected patients were the control group, and analyze the factors affecting postoperative infection, using Logistic regression software for multi-factor analysis. Results Among the 722 patients, 22 patients had postoperative infections, the infection rate was 3.05%, 14 males and 8 females. Univariate analysis showed that age, gender, high BMI, operation season, surgical risk index, etc. were all risk factors for postoperative infection(P<0.05). The age and operation time of the observation group were significantly longer than those of the control group(P<0.05). Multivariate logistic regression results showed that diabetes, ward conditions, high BMI, ASA grade, and incision classification were independent risk factors for incision infection(P<0.05), Backward-LR regression analysis of age, diabetes, incision classification and ASA grade are significantly related(P<0.05), among which the risk of diabetes was the highest. Conclusion Postoperative infection in general surgery patients is related to, surgical risk factor and underlying diseases. Postoperative infection prevention and control should be strengthened to reduce the incidence of infection.

普外科手術很多为胃肠道手术,属于污染手术,术中需要应用引流管[1],且容易受到其他因素的影响,术后感染发生率较高[2],严重影响患者预后,甚至引起患者死亡,因此普外科术后感染时不可忽视的关键,需要给予重视。杜绝术后感染虽然不太可能,但是术后感染存在危险因素,做好预防工作,能够有效降低感染发生率[3],减轻感染发生程度,在以往报道研究中发现患者年龄、性别、手术时机等都与术后感染发生存在相关性。为分析普外科患者术后感染发生率和影响因素,方便选取该院2016年9月—2019年3月普外科接受手术患者722例为研究对象,报道如下。
1 资料与方法
1.1 一般资料
方便选取该院普外科接受手术患者722例为研究对象,整理患者临床资料,手术方式包括胃大部切除术、结肠癌根治术、乳腺良性肿瘤切除术等。
1.2 方法
回顾性分析患者临床资料,观察患者切口愈合情况,详细询问患者病情发展情况,依照细菌学检查报告以及化验单等检查是否发生术后感染。……
