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.

       无创正压通气的使用是患者发生鼻面部压力性损伤的重要原因之一，随着我国防控政策的放开，新增老年新冠感染患者急剧增加。文章对使用无创正压通气发生相关压力性损伤现状进行综述，介绍老年患者使用无创正压通气发生鼻面部压力性损伤的主要影响因素、评估方法以及预防措施现状，旨在为临床医务人员预防其相关压力性损伤提供参考。
