Insights

Sevoflurane anesthesia offers rapid induction and emergence but may cause agitation and seizures. This review examines mechanisms and prevention strategies for these sevoflurane side effects.

Area of Science:

  • Anesthesiology
  • Neuroscience

Background:

  • Sevoflurane is a widely used inhalation anesthetic.
  • Its rapid onset and offset are clinically advantageous.
  • However, sevoflurane is associated with significant adverse effects.

Purpose of the Study:

  • To review the mechanisms underlying sevoflurane-induced agitation and epileptiform activity.
  • To explore strategies for preventing these adverse effects.

Main Methods:

  • Literature review of recent studies on sevoflurane anesthesia.
  • Analysis of mechanisms of action and clinical observations.

Main Results:

  • Agitation during induction and emergence is a common complication.
  • Sevoflurane may possess epileptogenic properties.
  • Several potential preventative strategies are discussed.

Conclusions:

  • The benefits of sevoflurane may be limited by its side effects.
  • Further research is needed to optimize sevoflurane use and mitigate risks.

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...

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...

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: 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.
Local Anesthetics: Adverse Effects01:12

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...
Local Anesthetics: Mechanism of Action01:23

Local Anesthetics: Mechanism of Action

Local anesthetics (LAs) block sensory and motor impulses by inhibiting the sodium channels on the nerve cell membranes. This induces temporary loss of sensation, relieving pain in a specific body area.
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
