据报道[1-2]，近年来重度肺部感染致病菌的耐药率逐年递增，且呈现多重耐药性，致使该病临床疗效差、治疗周期长、不良反应发生率高，严重影响患者康复进程。
早期、合理应用抗菌药物是治疗该病的关键[3]。
碳青霉烯类抗生素具有强效、广谱、低毒等优点,虽然临床应用已逾十数年，但鲜有菌株对其耐药，是治疗重度肺部感染的常见药物[4]。
本研究选择我院90例重度肺部感染患者作为研究对象，对比不同碳青霉烯类抗生素（亚胺培南及美罗培南）的有效性、安全性及经济性，现报道如下。
肺部感染属于常见的一种在肺泡腔等肺部实质发生炎症的呼吸道感染疾病，患者大多发病急，病因在于致病菌感染，临床症状表现为咳嗽、咳痰、胸痛、咳血、发烧、乏力等。
患者若不及时治疗，很容易进一步发展为重症肺部感染（如老年人、有合并多种基础疾病史），从而在短时间内出现意识障碍、休克、肝肾功能不全，甚至出现死亡，极大地威胁了患者的生命健康。
目前研究发现，造成重症肺部亚胺培南西司他丁钠和美罗培南对重症肺部感染患者的疗效及对细菌清除率、炎症因子水平的影响翁朝航厦门巿海沧医院，福建厦门 361026［摘要］目的：研究亚胺培南西司他丁钠和美罗培南对重症肺部感染患者的疗效及对细菌清除率、炎症因子水平的影响。
方法：选取2017年12月—2019年12月期间我院收治的120例重症肺部感染患者为观察对象，随机分为对照组和观察组，其中对照组60例患者在常规治疗基础上静脉滴注亚胺培南西司他丁钠；观察组60例患者在常规治疗基础上静脉滴注美罗培南，两组患者均治疗2周。
记录并对比两组患者治疗后的临床疗效、细菌清除率以及炎症因子水平的差异。
结果：经治疗后，观察组的总有效率（95.00%）显著高于对照组（81.67%），差异有统计学意义（P＜0.05）；观察组患者革兰阳性菌清除率及总体细菌清除率高于对照组，差异均有统计学意义（P＜0.05）；两组革兰阴性菌及真菌清除率比较，差异不具有统计学意义（P＞0.05）；两组患者经过治疗后的血清肿瘤坏死因子α、白介素-6、C反应蛋白以及降钙素原水平均明显低于治疗前，且观察组的各项炎症因子指标降低幅度较对照组更显著，差异有统计学意义（P＜0.05）；两组患者治疗期间不良反应发生率比较，差异无统计学意义（P＞0.05）。
结论：美罗培南在治疗重症肺部感染患者中具有较好的临床疗效，可显著改善患者的临床症状，提高细菌清除率，降低炎症因子水平，建议临床推广。

Methods: 120 patients with severe pulmonary infection in our hospital from December 2017 to December 2019 were selected as the observation objects and randomly divided into the control group and the observation group. 60 patients in the control group were given imipenem cilastatin sodium intravenous drip on the basis of conventional treatment; 60 patients in the observation group were treated with meropenem on the basis of conventional treatment, both groups were treated for 2 weeks. The clinical efficacy, bacterial clearance rate and inflammatory factor levels of the two groups were recorded and compared. Results: After treatment, the total effective rate of the observation group (95.00%) was significantly higher than that of the control group (81.67%), the difference was statistically significant (P＜0.05); the Gram-positive bacteria clearance rate and the overall bacterial clearance rate of the observation group were higher than those of the control group, the differences were statistically significant (P＜0.05); there was no significant difference in the clearance rate of Gram-negative bacteria and fungi between the two groups (P＞0.05); After treatment, the serum tumor necrosis factor alpha, interleukin-6, C-reactive protein and calcitonin in the two groups were significantly lower than before treatment, and the inflammatory factors in the observation group decreased more significantly than those in the control group (P＜0.05); there was no significant difference in the incidence of adverse reactions between the two groups during the treatment (P＞0.05). Conclusion: Meropenem in the treatment of patients with severe pulmonary infection has good clinical efficacy, can significantly improve the clinical symptoms of patients, improve the bacterial clearance rate, reduce the level of inflammatory factors, it is recommended that clinical promotion.[Key Words] Imipenem Cilastatin Sodium; Meropenem; Severe Pulmonary Infection; Efficacy; Bacterial Clearance Rate; Inflammatory Factors作者简介：翁朝航，本科，副主任医师。
