Summary
Anesthesia requires rapid, precise drug delivery due to absent patient feedback and lethal side effects. Model-based pharmacokinetic-pharmacodynamic (PK-PD) approaches, like target-controlled infusion (TCI), enable fast and reliable anesthetic dosing.
Area of Science:
- Anesthesiology
- Pharmacology
- Biomedical Engineering
Background:
- Anesthesia management presents unique challenges, including the inability to gauge patient response for dose adjustment and the critical risk of lethal side effects without intervention.
- Traditional titration methods are impractical due to the need for rapid, precise drug effect delivery within minutes.
Purpose of the Study:
- To outline the theory of model-based interactive drug dosing using pharmacokinetic-pharmacodynamic (PK-PD) models.
- To present target-controlled infusion (TCI) as an advanced anesthetic dosing technique.
Main Methods:
- Utilizing integrated pharmacokinetic-pharmacodynamic (PK-PD) models as a mathematical framework for drug delivery.
- Describing the principles of model-based interactive drug dosing.
- Introducing target-controlled infusion (TCI) as an open-loop dosing strategy.
Main Results:
- Integrated PK-PD models provide a robust framework for precise anesthetic drug delivery.
- Target-controlled infusion (TCI) systems represent a significant advancement in anesthetic dosing techniques.
- Current research focuses on developing adaptive closed-loop systems for individualized anesthetic administration.
Conclusions:
- Model-based approaches, including TCI, are essential for achieving rapid, reliable, and precise anesthetic drug delivery.
- Future research aims to enhance these systems through adaptive closed-loop control, further individualizing patient care.

01:24Parenteral Anesthetics: Overview
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.
01:24Rational Dosage Regimen: Maintenance Dose and Loading Dose
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady state,...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
01:15Drug Dosage Regimen: Overview
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

01:15Determination 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...
01:13Local Anesthetics: Pharmacokinetics
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...
