Parenteral Anesthetics: Overview01:24

Parenteral 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.

One-Compartment Open Model for IV Bolus Administration: General Considerations

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, half-life,...
General Anesthesia: Overview01:24

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...
Depolarizing Blockers: Pharmocokinetics01:19

Depolarizing Blockers: Pharmocokinetics

Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

IV Infusion to Oral Dosing: Conversion Methods

The development of extended-release formulations has facilitated the transition from intravenous to oral medication, offering a more convenient and patient-friendly approach to drug administration. This transition, however, requires careful management to ensure that therapeutic drug levels are maintained, preserving efficacy and avoiding adverse effects. Understanding pharmacokinetic principles and dosage calculations is critical during this process.Pharmacokinetics of the...

Area of Science:

  • Medical technology
  • Anesthesiology
  • Gastroenterology

Background:

  • Propofol sedation in endoscopy offers potential benefits like improved sedation quality, faster recovery, and increased patient throughput.
  • The efficacy and cost-effectiveness of propofol sedation depend on required personnel and resources.
  • Computer-based platforms offer a promising approach to safe and effective propofol administration.

Purpose of the Study:

  • To evaluate computer-based platforms for propofol sedation in endoscopic procedures.
  • To explore the utility of electronic adjuncts in optimizing propofol sedation delivery.
  • To assess how these technologies can support endoscopists in adopting propofol sedation.

Main Methods:

  • Utilizing computer-based platforms that monitor patient responses to stimulation and physiological parameters.
  • Employing bispectral index (BIS) monitoring with continuous electroencephalogram (EEG) recordings to assess sedation depth.
  • Implementing closed-loop target-controlled systems that use physical parameters (e.g., muscle relaxation, auditory-evoked potentials) to regulate medication dosage.
  • Considering patient-controlled sedation platforms.

Main Results:

  • Computer-based platforms provide an appealing method for delivering safe and effective propofol doses.
  • Bispectral index monitoring allows for continuous assessment of sedation levels.
  • Closed-loop systems adjust medication based on physiological feedback for appropriate sedation.
  • Patient-controlled platforms are also an option.

Conclusions:

  • Electronic adjuncts can enhance the safety and effectiveness of propofol sedation in endoscopy.
  • These technologies empower endoscopists to adopt propofol sedation with increased confidence.
  • Computer-based sedation management may facilitate better quality of care and operational efficiency in endoscopy units.
