目的 探究高龄患者植入静脉输液港并发感染相关影响因素分析。方法 随机抽取我院2015年5月—2018年8月期间收入高龄患者总计72例,对并发感染患者数量进行统计,采取Logistic回归方程进行计算,分析高龄患者植入静脉输液港并发感染相关因素。结果 共计纳入植入静脉输液港并发感染患者总计72例,其中并发感染患者为23例,占比31.94%,对比两组一般资料,发现两组患者在穿刺部位、疾病种类、使用时间及频率、是否有糖尿病史、体质量上存在差异,数据对比差异有统计学意义(P＜0.05),将上述有差异资料带入Logistic回归方程计算,发现穿刺部位、疾病种类、使用时间及频率、是否有糖尿病史、体质量均为导致高龄患者植入静脉输液港并发感染影响因素。结论 对高龄患者而言,植入静脉输液港并发感染各项因素中,包括穿刺部位、疾病种类、使用时间及频率、是否有糖尿病史、体质量,患者需加强关注,可控制输液港相关感染。

Objective To explore the influencing factors of infection in elderly patients with intravenous infusion port. Methods 72 elderly patients from May 2015 to August 2018 were randomly selected in our hospital. After counting the number of patients with complicated infection,the relative factors of infection in elderly patients were analyzed by using the Logistic regression equation. Results A total of 72 patients were included in the intravenous infusion port with concurrent infection,of which 23 were accompanied with infection,accounting for 31.94%.By comparing the general data,two groups in puncture sites,types of diseases,application times and frequencies,histories of diabetes and body masses had statistically difference(P<0.05). It was found all the above factors were the concomitant factors leading to the implantation of intravenous infusion port in elderly patients by putting the difference data into the Logistic regression equation. Conclusion To control infusion port related infection,the elderly patients should focus more on the infection factors of the implantation in intravenous infusion port which included puncture sites,types of diseases,application times and frequencies,histories of diabetes and body masses.

目的 探讨高龄患者（≥65岁）腹股沟嵌顿疝术后肺部感染的相关因素。方法 以我院手术治疗的60例腹股沟嵌顿疝术后肺部感染的高龄患者为观察组,行1∶1匹配病例对照研究,应用单因素及多因素条件Logistic回归对相关因素进行分析,计算各因素与肺部感染的OR值及其95%可信区间。结果 研究提示术前血清白蛋白≤35 g/L（P=0.013）、术前血红蛋白≤100 g/L（P=0.029）、既往慢性阻塞性肺气肿病史（P=0.014）及抽烟（P=0.008）、手术时间≥2 h（P=0.021）、手术切除部分肠管（P=0.032）、气管插管（P=0.024）、手术季节为冬季（P=0.030）为危险因素;预防性使用抗生素（P=0.018）、术后雾化（P=0.023）、良好睡眠（P=0.048）为保护因素。结论 高龄患者腹股沟嵌顿疝术后肺部感染的发生与相关生化指标、既往史、治疗过程、环境因素等密切相关。

Objective To investigate the correlation factors of elderly patients with inguinal incarcerated hernia surgery related lung infection. Methods A hospital-based 1∶1 matched case-control study was conducted among elderly patients with inguinal incarcerated hernia surgery related lung infection,calculated the factors associated with the extent of lung infection,and the 95% confidence interval. Results The analysis showed that pre-ALB≤35g/L（P=0.013）,pre-Hb≤100g/L（P=0.029）,COPD（P=0.014）,smoking（P=0.008）,operation time（P=0.021）,bowel resection（P=0.032）,endotracheal intubation（P=0.024） and operation in winter（P=0.030） were the risk factors of lung infection,while the prophylactic use of antibiotics（P=0.018）,aerosol inhalation（P=0.023） and good sleep（P=0.048） were the protective factors. Conclusion Some biochemical indicators,past history,therapeutic process and environmental factors were closely related to inguinal incarcerated hernia surgery related lung infection in elderly patients.
