概括
身体外膜氧化 (ECMO) 在ICU患者中显著改变cefepime的药理动力学,导致较高的自由Cmax但较低的fCmin/MIC目标. 对于ECMO患者来说,可能需要更激烈的cefepime剂量.
科学领域:
- 药理学 药理学是指药理学的学科.
- 关键护理医学 关键护理医学
- 传染性疾病 传染性疾病
背景情况:
- 关于体外膜氧化 (ECMO) 对β-乳糖抗生素药理动力学/药理动力学 (PK/PD) 的影响的数据有限.
- 在ECMO患者中Cefepime的PK/PD数据特别稀缺.
- 了解这些影响对于优化重症患者的抗生素治疗至关重要.
研究的目的:
- 调查ECMO对成人重症监护室 (ICU) 患者塞费皮姆药理学 (PK) 的影响.
- 为了比较ECMO和非ECMO患者之间的cefepime PK/PD参数.
主要方法:
- 单中心,回顾性病例控制研究.
- 对ECMO和非ECMOICU患者的1:1匹配比较,基于cefepime疗程和功能.
- 对治疗药物监测 (TDM) 数据对塞费皮姆度的分析.
主要成果:
- 在ECMO患者中,自由最大度 (fCmax) 较高,但自由最小度 (fCmin) /MIC比率较低,并且达到fCmin/4x MIC目标.
- 没有观察到自由Cmin,MIC以上时间或核心PK参数 (ke,半衰期,VD) 的显著差异.
- 在ECMO患者中,住院时间更长,治疗失败率更高,尽管存活率和抗药率相似.
结论:
- 由于ECMO会改变cefepime PK/PD,因此可能需要更具侵略性的实证剂量策略.
- 建议在ECMO患者中对塞费皮姆进行治疗药物监测.
- 需要进一步的前性研究来完善剂量指南.

Two-Compartment Open Model: Extravascular Administration
209
The two-compartment model for extravascular administration represents a drug's absorption and distribution process. It features a central compartment, where the drug is first absorbed, and a peripheral compartment, which illustrates the drug's distribution throughout the body. The rate of change in drug concentration in the central compartment is calculated by three exponents: absorption, distribution, and elimination.
The absorption exponent (ka) indicates the speed at which the drug...

Drug Concentration Versus Time Correlation
796
The plasma drug concentration-time curve is a crucial tool in pharmacokinetics, representing the drug's concentration in plasma at different time intervals post-administration. This curve illustrates the drug's journey from absorption into the systemic circulation, distribution to body tissues, and eventual elimination through excretion or biotransformation.
Two pivotal parameters are the minimum effective concentration (MEC) and the minimum toxic concentration (MTC). The MEC is the...
