简化和复杂的阿米卡辛剂量方案都实现了新生儿败血症治疗100%的目标. 这表明,任何一种剂量方法都是有效的,允许根据当地需求和可用的工具进行临床灵活性.
科学领域:
- 新生儿药理学 新生儿药理学
- 抗生素剂量策略 抗生素剂量策略
- 药理动力学/药理动力学 (PK/PD) 是一个
背景情况:
- 阿米卡辛是治疗新生儿败血症的关键抗生素.
- 目前荷兰儿科表格的建议涉及一个复杂的,模型衍生的剂量方案.
- 简化阿米卡辛的剂量方案可以提高临床适用性.
研究的目的:
- 评估和比较新生儿使用简化与复杂剂量方案实现阿米卡的药理动力学/药理动力学 (PK/PD) 目标.
- 为了确定一个简化的阿米卡辛剂量策略是否可以实现新生儿败血症治疗的足够的PK/PD目标.
主要方法:
- 追溯队列研究,比较接受简化 (阿姆斯特丹UMC) 和复杂 (卢旺大学医院) 阿米卡辛剂量方案的新生儿.
- 用于计算第一剂量间隔的峰值 (Cmax),低谷 (Cmin) 度和曲线下的面积 (AUC) 的贝叶斯估计.
- 评估的PK/PD目标包括Cmax (≥15,≥25,≥35 mg/L),Cmin (≤3,≤5 mg/L) 和AUC/MIC (2,4,8 mg/L) 对于细菌静止和1-log降低.
主要成果:
- 简化和复杂的阿米卡辛剂量方案都实现了100%的Cmax ≥15 mg/L,Cmin ≤5 mg/L,以及细菌静止和1-log降低的AUC/MIC,达到2 mg/L的MIC.
- 在不太严格的目标 (Cmax ≥ 15 mg/L,Cmin ≤ 5 mg/L,细菌静止的AUC/MIC) 中,在两种方案中都观察到足够的目标实现.
- 总共有366名新生儿 (768个度) 和579名新生儿 (1,195个度) 分别被纳入简化和复杂疗法组.
结论:
- 简化和复杂的阿米卡辛剂量方案都表明,在新生儿中有效地实现了PK/PD目标.
- 临床医生可以根据当地情况和集成电子处方工具的可用性选择任何剂量方案.
- 这些发现支持使用简化阿米卡辛剂量方案,以改善新生儿败血症管理的临床实践.
