目的探讨乳酸左氧氟沙星氯化钠注射液(来立信)治疗社区获得性肺炎的疗效。方法将60例社区获得性肺炎随机分为2组,来立信治疗组及对照组各30例。来立信治疗组应用来立信0.3g静脉滴注,每12小时1次;对照组应用头孢哌酮舒巴坦钠2g静脉滴注,每12小时1次。2组疗程均为7～14d。结果来立信治疗组总有效率为93.3%(28/30),对照组总有效率为70.0%(21/30),2组总有效率比较,差异具有统计学意义(P<0.05)。结论来立信对社区获得性肺炎具有良好疗效。 Objective To investigate the efficacy of levofloxacin lactate sodium chloride injection (Lixin) in the treatment of community-acquired pneumonia. Methods Sixty patients with community-acquired pneumonia were randomly divided into two groups, and each group received 30 cases of Lirin treatment group and control group. To Ericsson treatment group should be used to set the letter 0.3g intravenous infusion, once every 12 hours; the control group cefoperazone sulbactam sodium 2g intravenous infusion every 12 hours. 2 groups of treatment are 7 ~ 14d. Results The total effective rate in Lixin treatment group was 93.3% (28/30), while the total effective rate in control group was 70.0% (21/30). The total effective rate in two groups was statistically significant (P <0.05). Conclusion Ericsson has good effect on community-acquired pneumonia.
