概括
对间歇性HD患者来说,高剂量血清透析 (HD) 后的Ceftazidime/avibactam剂量是可行的,但Cefepime和Meropenem可能需要调整剂量. 较高的塞费皮姆剂量会产生神经毒性风险,需要仔细的管理和监测.
科学领域:
- 药理动力学和药理动力学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 传染性疾病 传染性疾病
背景情况:
- 每天静脉注射的抗生素用于间歇性血液透析 (IHD) 患者需要经常访问诊所.
- 门诊高剂量后HD管理是一种潜在的替代方案,但缺乏支持数据.
研究的目的:
- 为了评估药理动力学/药理动力学 (PK/PD) 目标的实现和HD后的神经毒性风险,与IHD患者每日服用塞费皮姆,梅罗和塞法齐迪姆/阿维巴克坦的剂量相比.
- 使用蒙特卡洛模拟 (MCS) 来比较剂量策略.
主要方法:
- 开发了一种单间药理动力学模型,用于IHD的无尿患者.
- 采用MCS来评估各种剂量方案实现目标 (PTA) 的概率和神经毒性风险.
- PK/PD的目标包括%T>MIC的cefepime,meropenem和ceftazidime,以及%T>1g/mL的avibactam.
主要成果:
- 每日治疗方案实现了最佳的PTA (≥90%).
- 后HD cefepime和meropenem在3天的时间间隔中未能维持目标; ceftazidime/avibactam保持了目标,但avibactam略有下降.
- 较高的塞费皮姆剂量 (HD后和每日) 预测了神经毒性风险升高;美罗和塞夫塔齐迪姆/阿维巴克坦显示的风险微不足道.
结论:
- 高剂量后HD剂量是可行的ceftazidime/avibactam,但可能不够的cefepime和meropenem超过3天的透析期间.
- 较高的塞费皮姆剂量与神经毒性风险的增加有关.
- 确定了针对塞费皮姆,梅罗和塞夫塔齐迪姆/阿维巴克坦的优化剂量方案,实现了PK/PD和安全目标.

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant
198
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...

Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations

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...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
175
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Hemodialysis I: Introduction
1.2K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
