目的：通过：logistic回归分析，了解老年胃癌病人行外科手术治疗后并发肺部感染的危险因素及护理对策，并且针对危险因素进行干预。方法收集280例老年胃癌术后患者的基础信息及临床资料，发生肺部感染的患者60例，未发生肺部感染的220例，观察患者的年龄、性别、是否有吸烟史、是否有基础疾病，是否采用持续性胃肠减压，是否早起下床活动，术后是否常规采用抗生素治疗，以非条件logistic回归分析方法分析相关的危险因素。结果在单因素的logistic回归分析中，患者是否＞65岁，是否吸烟，是否使用胃肠减压，是否早起下床活动是危险因素5个因素具有统计学意义（ P＜0．05）；多因素分析得到是否吸烟，是否胃肠减压为老年胃癌肺部感染的危险因素，而是否早期下床活动为保护性因素。结论伴有术后胃肠减压患者及是否有吸烟史的患者胃癌术后患者容易出现肺部感染，需高度重视，而早期下床活动则是保护性措施。%Objective The logistic regression was used to analysis the elderly patients with lung infection after gastric cancer surgery and nursing countermeasure and special intervention against the risk factors.Methods 280 patients after gastric cancer surgery was included,60 patients with lung infection, their information and clinical data including age, gender, history of smoking, underlying disease, persistent decompression, early ambulation and antibiotic therapy after surgery were collected and subjected to non-conditional logistic regression analysis.Results Single logistic regression showed the age >65, smoking, persistent decompression and early ambulation were risk factors, and smoking, persistent decompression were risk factors,but early ambulation was protective factors in the multivariate logistic regression analy-sis.Conclusions The patients with smoking and persistent decompression are prone to lung infection and need special intervention, however early ambulation was protective factor.
