【摘要】目的：观察左氧氟沙星注射液联合乙酰半胱氨酸吸入剂治疗重症肺炎的疗效。方法：在2023年1月—2023年8月期间，共纳入260例重症肺炎患者，随机将其分为观察组和对照组，每组130例。对照组采用常规治疗，观察组在对照组的基础上加用左氧氟沙星注射液联合乙酰半胱氨酸吸入剂治疗，比较两组治疗效果。结果：治疗后，观察组患者的咳嗽、咳痰、气喘等症状改善率为93.08%(121/130)，高于对照组的65.38%(85/130)，差异具有统计学意义(P<0.05)；治疗后，观察组PaCO2、PaO2等血气指标明显优于对照组，差异具有统计学意义(P<0.05)；观察组治疗总有效率明显高于对照组，差异具有统计学意义(P<0.05)。结论：左氧氟沙星注射液联合乙酰半胱氨酸吸入剂对于重症肺炎的治疗具有显著效果。
