概括
修改后的马什和施奈德的药理动力学模型在临床上是可接受的目标控制输注 (TCI) 的propofol与中长链甘油三 (MCT/LCT) 配方. 他们的预测性能对于全身麻醉仍然可靠.
科学领域:
- 麻醉学 麻醉学
- 药理动力学 药理动力学
- 药物配方 药物配方 药物配方
背景情况:
- 中长链甘油三 (MCT/LCT) 醇配方越来越多地使用,取代长链甘油三 (LCT) 醇.
- 现有的药理动力学模型 (Marsh和Schnider) 使用LCT propofol进行了开发.
- 这些模型对MCT/LCT的适用性要求对目标控制输注 (TCI) 进行验证.
研究的目的:
- 评估TCI期间对MCT/LCTpropofol修改的马什和施奈德药理动力学模型的预测性能.
- 评估新配方的已建立的propofol TCI模型的外部适用性.
主要方法:
- 成年患者 (n=48) 通过TCI使用修改后的Marsh或Schnider模型接受MCT/LCT普罗波.
- 采集了血液样本以测量使用高性能液态染色学测量实际的propofol血度.
- 使用不准确性,偏差,分歧和摇摆参数量化模型预测性能.
主要成果:
- 修改后的马什和施奈德模型都显示了MCT/LCT propofol的临床可接受的预测性能.
- 不准确率为24.4% (马什) 和26.9% (施奈德);偏差率为16.4% (马什) 和16.6% (施奈德).
- 预测性能与LCT propofol可比,在更高的目标度 (3.55μg/ml) 中偏差和不准确性更高.
结论:
- 修改后的马什和施奈德模型在临床上对MCT/LCT propofol的TCI是可以接受的.
- 配方变化似乎对全身麻醉中TCI系统可靠性的影响很小.
- 这些模型仍然适合使用较新的propofol配方.

Parenteral Anesthetics: Overview
125
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

One-Compartment Open Model for IV Bolus Administration: General Considerations
201
The one-compartment model is a pharmacokinetic tool that models the body as a single, uniform compartment, facilitating the understanding of drug distribution and elimination. This model is particularly beneficial for intravenous (IV) bolus administration, where the drug rapidly circulates throughout the body.
The drug's presence in the body is defined by an equation representing the difference between the rates of drug entry and exit. Key parameters—elimination rate constant,...
