    Insights

    Inhalational anesthetics cause specific side effects beyond narcosis by binding to macromolecules. These interactions alter cell functions, leading to toxicity and potential immune responses, impacting cellular processes.

    Area of Science:

    • Anesthesiology
    • Cellular Biology
    • Pharmacology

    Background:

    • Inhalational anesthetics induce narcosis but also exhibit specific, non-uniform side effects.
    • These side effects are not due to general cell function depression but specific molecular interactions.

    Purpose of the Study:

    • To elucidate the specific mechanisms underlying the side effects of inhalational anesthetics.
    • To understand how anesthetic-induced molecular changes impact cellular functions and toxicity.

    Main Methods:

    • Analysis of anesthetic binding to hydrophobic sites in macromolecules.
    • Observation of conformational changes in macromolecules and their functional consequences.
    • Investigation of cellular toxicity resulting from anesthetic biotransformation products.

    Main Results:

    • Anesthetics bind to hydrophobic sites, causing conformational changes in macromolecules like enzymes and microtubules.
    • Observed effects include enzyme inactivation, microtubule depolymerization, and paralysis of motile systems.
    • Cellular toxicity arises from biotransformation products, free radicals, membrane disruption, and autolysis.
    • Immune responses to anesthetics and their metabolites were detected.

    Conclusions:

    • The specific side effects of inhalational anesthetics stem from targeted molecular interactions and subsequent cellular dysfunction.
    • Anesthetic-induced cellular damage and potential immune responses warrant further investigation for clinical relevance.

    Local 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...

    Local Anesthetics: Adverse Effects

    While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
    Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...
    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...
    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.
    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...

    Cellular Injury IV: Necrosis

    Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
