[Abstracts] Objective This paper tries to analyze the feasibility of high-dose levofloxacin injection in elderly patients with respiratory tract infection. Methods A total of 84 elderly patients with respiratory tract infection were convenient selection in this study from June 2015 to January 2017 and were randomly grouped. 42 patients in the control group were treated with cefoperazone sodium and 42 patients in the levofloxacin group were treated with high-dose levofloxacin injection. The treatment effect of respiratory tract infection of the two groups, the time of control of respiratory tract infection, the time of hospitalization, the level of white blood cells and the level of C-reactive protein before and after intervention, and the occurrence of adverse reaction were compared. Results The curative effect of levofloxacin group on respiratory tract infection was 95.24%, higher than that of the control group of 80.95%(P 1 资料与方法
1.1 一般资料
方便选取84例老年呼吸道感染患者并随机分组。所有患者出现不同程度呼吸困难、咳嗽、脓痰等症状,经查体、病原学和实验室检查符合呼吸道感染诊断标准[3]。所有患者签署知情同意书,对该研究药物均无禁忌。
左氧氟沙星组研究对象男27例,女15例;年龄62~83岁,平均年龄为(71.61±2.45)岁。其中,慢性支气管炎24例,扁桃体炎14例,其他7例。对照组研究对象男28例,女14例;年龄61~83岁,平均年龄为(71.77±2.42)岁。其中,慢性支气管炎24例,扁桃体炎15例,其他6例。两组一般资料相似,差异无统计学意义(P>0.05)。
1.2 方法
对照组采用头孢哌酮钠进行治疗,2 g头孢哌酮钠(国药准字H23021446)和300 mL浓度5%葡萄糖溶液静脉滴注,2次/d,治疗1~2周。左氧氟沙星组应用高剂量左氧氟沙星注射液(国药准字H20060337)治疗。500 mg静脉滴注,1次/d,滴注时间≥1 h,治疗1~2周[4]。
1.3 观察指标
比较两组研究对象呼吸道感染治疗效果;呼吸道感染症状得到控制的时间、住院接受治疗的时间;干预前后患者白细胞水平、C反应蛋白水平。
显效:症状、体征、实验室检查、病原学检查4项均正常;有效:症状、体征、实验室检查、病原学检查4项有1项不正常;无效:症状、体征、实验室检查、病原学检查4项有2项及以上不正常。呼吸道感染治疗效果为显效、有效百分率之和[5]。
1.4 统计方法
数据采用SPSS 22.0统计学软件统计分析,计量资料(x±s)、计数资料[n(%)]分?e用t检验和χ2检验,P0.05);干预后左氧氟沙星组白细胞水平、C反应蛋白水平优于对照组(P0.05);干预后左氧氟沙星组白细胞水平、C反应蛋白水平优于对照组(P参考文献]
