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.
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...
Stages of General Anesthesia01:22

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
Inhalational Anesthetics: Overview01:20

Inhalational Anesthetics: Overview

Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Area of Science:

  • Biochemistry
  • Anesthesiology
  • Molecular Biology

Background:

  • Inhaled anesthetics are known to affect protein structure and function.
  • Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has been shown to interact with anesthetic agents.
  • GAPDH also regulates the function of GABA (type A) receptors, which are targets of anesthetics.

Purpose of the Study:

  • To discuss the potential role of GAPDH in anesthesia based on existing literature.
  • To describe the binding sites of inhaled anesthetics on model proteins and GABA receptors.
  • To explore GAPDH's involvement in anesthetic preconditioning.

Main Methods:

  • Literature review of studies on inhaled anesthetics, GAPDH, and GABA receptors.
  • Analysis of binding site characteristics from model proteins (human serum albumin, apoferritin).
  • Examination of the proposed mechanism of anesthetic preconditioning involving protein dehydration and chaperone expression.

Main Results:

  • Inhaled anesthetics directly alter GAPDH structure and function.
  • GAPDH regulates GABA (type A) receptor activity.
  • A putative binding site for anesthetics on GAPDH involves both hydrophobic and hydrophilic residues.
  • Anesthetic preconditioning may involve GAPDH-mediated cellular responses to protein dehydration.

Conclusions:

  • GAPDH is a potential key player in the mechanism of inhaled anesthesia.
  • The interaction of anesthetics with GAPDH and its role in GABA receptor function warrant further investigation.
  • GAPDH may mediate protective cellular responses through anesthetic preconditioning, involving chaperone pathways.
