Plos one:抗菌药物降阶梯治疗的好处和意想不到的后果

连续抗菌药物降级治疗旨在当实验室检验确定药物敏感性时转换为敏感药物,以此达到最大限度地降低对高广谱经验抗微生物药物的耐药性。


虽然临床广泛使用,但是抗菌药物的降级仍然难以理解。各种干预和结果的定义在不同的研究之间各不相同。

近期,一项发表在Plos one杂志上的研究使用铜绿假单胞菌在重症监护室中的传播和进化模型,以评估药物降级对患者结局的影响。

在此项研究中,抗菌药物降级减少了高广谱药物的使用,并能保持经验性治疗的有效性,但与此同时也使的细菌产生了选择性多药耐药菌株,并使患者易于发生细菌定植和重叠感染。在此项研究中,抗菌药物降级可以增加感染流行率,但同时也增加有效治疗的可能性。死亡率的变化很小,可以是阳性结果也可以使阴性结果。

这些临床结果(如感染流行率和死亡)微小变化的意义可能超过更容易检测到的药物使用和耐药性的变化。将伤害和利益综合到每个患者的中可以在这些权衡的分析中提供一种新方式。此项研究提供了一个概念框架,用于更好的进行抗菌素管理。

2016创伤后抗菌药物预防性应用专家共识发布

抗菌药物的应用包括预防性和治疗性应用,其中预防性应用是预防特定病原菌所致或特定人群可能发生的感染,用于尚无细菌感染征象但暴露于致病菌感染的高危人群。创伤后容易发生感染,抗菌药物的使用是防治创伤感染的重要措施之一。正确使用抗菌药物,避免过度使用和使用不足,对于改善患者预后、减少并发症、减轻社会和家庭的医疗负担、减少和延缓细菌耐药的发生都具有重要意义。本共识主要针对非战伤所致创伤抗菌药的物预防性应用,
