Parenteral Anesthetics: Overview

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: Overview

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

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...

Pharmacology

Background:

Remifentanil is an ultra-short-acting opioid frequently used in neuroanesthesia and neurointensive care.
Concerns exist regarding its potential neurotoxicity, particularly in ischemic brain conditions.
Understanding its central nervous system effects is critical for safe clinical application.

Purpose of the Study:

To review current information on remifentanil's effects on the central nervous system.
To evaluate its safety profile in neuroanesthesia and neurocritical care settings.

Main Methods:

A systematic literature search of MEDLINE was conducted.
The search focused on studies published within the last seven years concerning remifentanil and brain function.
Information on various neurological parameters was synthesized.

Main Results:

Remifentanil influences cerebral metabolism, electroencephalogram, and motor-evoked potentials.
Effects on cerebral blood flow, intracranial pressure, and cerebrovascular reactivity were analyzed.
Data on analgesia, hyperalgesia, neuroprotection, neurotoxicity, and hypothermia were considered.

Conclusions:

Comprehensive knowledge of remifentanil's impact on brain function is essential.
This knowledge is crucial for optimizing anesthesia practices and enhancing patient safety in neurocritical care.
Improved understanding can lead to better patient outcomes.
