目的观察青霉素G和左氧氟沙星治疗肺炎链球菌肺炎的临床疗效。方法选取医院收治的肺炎链球菌肺炎患者60例为研究对象,随机分为观察组和对照组各30例。对照组采用青霉素G治疗,观察组采用左氧氟沙星治疗,比较2组患者的治疗效果和不良发应发生情况。结果治疗后,观察组总有效率为96.7%,优于对照组的83.3%(P<0.05);2组不良反应发生率比较,差异无统计学意义(P>0.05)。结论在肺炎链球菌肺炎患者治疗中,采用左氧氟沙星疗效显著,可提高治疗有效率,促进患者早日康复,值得在临床推广应用。 Objective To observe the clinical efficacy of penicillin G and levofloxacin in the treatment of pneumococcal pneumonia. Methods Sixty patients with pneumococcal pneumonia admitted to the hospital were selected as study subjects and randomly divided into observation group and control group with 30 cases each. The control group was treated with penicillin G, and the observation group was treated with levofloxacin. The treatment effect and incidence of adverse reactions in the two groups were compared. Results After treatment, the total effective rate in the observation group was 96.7%, which was better than 83.3% in the control group (P <0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P> 0.05). Conclusion In the treatment of patients with pneumococcal pneumonia, levofloxacin has a significant effect, which can improve the treatment efficiency and promote the early recovery of patients, which is worthy of clinical application.
