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.

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...

General Anesthesia: Overview

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: Pharmocokinetics

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...

Local Anesthetics: Clinical Application as Spinal Anesthesia

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Background:

Ketamine, an N-methyl-D-aspartate (NMDA) antagonist, shows neuroprotective effects in experimental ischemia.
High-quality neuronal preparations are crucial for accurate electrophysiological studies.

Purpose of the Study:

To investigate the impact of ketamine-induced deep anesthesia on the quality of neonatal mouse brain slice preparations.
To assess the electrophysiological properties of specific neuronal populations after ketamine treatment.

Main Methods:

Neonatal mice were subjected to deep anesthesia with ketamine prior to euthanasia and brain extraction.
Electrophysiological recordings were performed on neurons from the locus coeruleus (LC) and hypoglossal nucleus.
Input resistance and voltage clamp reliability were measured and compared to control groups.

Main Results:

Ketamine anesthesia significantly improved neuronal input resistance in both LC and hypoglossal neurons.
LC neurons, typically challenging to voltage clamp, demonstrated improved control under ketamine anesthesia.
Overall enhanced electrophysiological properties suggest superior neuronal health and function in ketamine-treated slices.

Conclusions:

Ketamine-induced deep anesthesia is a valuable method for improving the quality of neonatal mouse brain slice preparations.
This technique enhances the electrophysiological integrity of key neuronal populations, facilitating more reliable research.
The findings support the use of ketamine as a pre-treatment to optimize neuronal slice quality for neuroscience research.
