まとめ
集中治療室の患者における連続的腎代替療法(CRRT)中の抗菌薬投与量の最適化は極めて重要である。探索的解析では、CRRT中の不適切な抗菌薬投与量が耐性増加に関連していた。
科学分野:
- 集中治療医学
- 薬理学
- 腎臓病学
背景:
- 連続的腎代替療法(CRRT)を受けている重症患者における抗菌薬投与は、大きな課題をもたらします。
- 変化した薬物動態、CRRTの変動性、および限られたガイダンスは、抗菌薬耐性および毒性を防ぐために最適化された投与量を必要とします。
研究 の 目的:
- CRRTを受けている集中治療室(ICU)患者における抗菌薬投与戦略を評価すること。
- CRRTパラメータ、抗菌薬投与量、および抗菌薬耐性の発達との関連を調査すること。
主な方法:
- CRRTおよびセフェピム、メロペネム、またはピペラシリン-タゾバクタムを受けているICU患者の後ろ向き単一施設研究。
- Pseudomonas aeruginosaおよびEnterobacter cloacaeにおけるCRRTで届けられた投与量、1日あたりの抗菌薬投与量、および耐性発達の分析。
主要な成果:
- ほとんどの患者は、KDIGOガイドラインで推奨されている量よりも多いCRRT量を受けていました。
- CRRT中の低い1日あたりの抗菌薬投与量は、セフェピムおよびメロペネム耐性の増加と独立して関連していました。
- P. aeruginosaおよびE. cloacaeにおける治療誘発性耐性が観察されました。
結論:
- CRRT中に投与された抗菌薬量は、治療範囲を下回ることが多かった。
- 結果は、CRRTを考慮した投与戦略が抗菌薬耐性の管理に重要である可能性を示唆しています。
- CRRT患者における抗菌薬の効果と毒性のバランスをとることが不可欠です。

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant
207
In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...

Continuous Renal Replacement Therapy
817
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Renal Failure: Dose Adjustments
434
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...
