Crit Care:用于呼吸机相关性肺炎的雾化抗生素治疗

2018-11-16 xing.T MedSci原创

由此可见,雾化抗生素似乎是VAP在临床恢复和微生物根除方面有用的治疗方法,并且不会增加死亡率或肾毒性风险。研究人员对VAP患者的网络荟萃分析表明,临床恢复益处与雾化妥布霉素和粘菌素(特别是妥布霉素)、气雾化粘菌素的微生物根除和雾化妥布霉素的存活相关,主要基于观察性研究。由于证据水平较低,在额外的大型随机研究之前无法得出明确的建议。

有研究已经提出采用雾化抗生素作为治疗呼吸机相关性肺炎(VAP)的新型和有希望的治疗选择。然而,VAP的最佳雾化抗生素尚未确定。

近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,研究人员纳入了两项系统评价的研究,并检索了PubMed、EMBASE和Cochrane数据库中其它研究。符合条件的研究包括随机对照试验和观察性研究。通过成对和网络荟萃分析分析提取的数据。

该分析确定了8项观察和8项随机研究。研究人员通过使用静脉注射抗生素作为参考进行成对荟萃分析,发现采用雾化抗生素治疗的患者具有显著更高的临床恢复率(风险比(RR)为1.21,95%置信区间(CI)为1.09-1.34; P=0.001)和微生物根除(RR为1.42,95%CI为1.22-1.650; P<0.0001)。死亡风险(RR为0.88,95%CI为0.74-1.04; P=0.127)或肾毒性(RR为1.00,95%CI为0.72-1.39; P=0.995)无显著差异。通过网络荟萃分析,仅在使用雾化妥布霉素和粘菌素(尤其是妥布霉素)观察到临床恢复益处,并且仅使用粘菌素才能看到微生物根除益处。与雾化阿米卡星和粘菌素和静脉注射抗生素相比,雾化妥布霉素也可显著患者降低死亡率。等级概率评估表明雾化妥布霉素最有可能获得临床恢复和死亡益处,并且雾化粘菌素为微生物根除提供了最好的益处。

由此可见,雾化抗生素似乎是VAP在临床恢复和微生物根除方面有用的治疗方法,并且不会增加死亡率或肾毒性风险。研究人员对VAP患者的网络荟萃分析表明,临床恢复益处与雾化妥布霉素和粘菌素(特别是妥布霉素)、气雾化粘菌素的微生物根除和雾化妥布霉素的存活相关,主要基于观察性研究。由于证据水平较低,在额外的大型随机研究之前无法得出明确的建议。
