Common anesthetic molecules prefer to partition in liquid disorder phase domain in a composite multicomponent membrane [PDF]

open access: yesPhys. Rev. E 98, 012409 (2018), 2018
Despite a vast clinical application of anesthetics, the molecular level of understanding of general anesthesia is far from our reach. Using atomistic molecular dynamics simulation, we study the effects of common anesthetics: ethanol, chloroform and methanol in the fully hydrated symmetric multicomponent lipid bilayer membrane comprising of an ...

Tryptophan and Cysteine Mutations in M1 Helices of &agr;1&bgr;3&ggr;2L &ggr;-Aminobutyric Acid Type A Receptors Indicate Distinct Intersubunit Sites for Four Intravenous Anesthetics and One Orphan Site

open access: yesAnesthesiology, 2016
Background:&ggr;-Aminobutyric acid type A (GABAA) receptors mediate important effects of intravenous general anesthetics. Photolabel derivatives of etomidate, propofol, barbiturates, and a neurosteroid get incorporated in GABAA receptor transmembrane ...

Effect of preoperative dexmedetomidine nebulization on the hemodynamic response to laryngoscopy and intubation: a randomized control trial [PDF]

open access: yesKorean Journal of Anesthesiology, 2021
Background Dexmedetomidine, an alpha-2 agonist, has been used for attenuation of hemodynamic response to laryngoscopy but not through the nebulized route.

Membrane Nanodomains Homeostasis During Propofol Anesthesia as Function of Dosage and Temperature [PDF]

open access: yes, 2020
Some anesthetics bind and potentiate gamma-aminobutyric-acid-type receptors, but no universal mechanism for general anesthesia is known. Furthermore, often encountered complications such as anesthesia induced amnesia are not understood. General anesthetics are hydrophobic molecules easily dissolving into lipid bilayers.

Edge AI-Based Vein Detector for Efficient Venipuncture in the Antecubital Fossa [PDF]

open access: yes, 2023
Assessing the condition and visibility of veins is a crucial step before obtaining intravenous access in the antecubital fossa, which is a common procedure to draw blood or administer intravenous therapies (IV therapies). Even though medical practitioners are highly skilled at intravenous cannulation, they usually struggle to perform the procedure in ...

Comparison of the effect of intravenous anesthetics used for anesthesia during electroconvulsive therapy on the hemodynamic safety and the course of ECT.

open access: yesPsychiatria Polska, 2017
Electroconvulsive therapy (ECT) is the treatment method widely used in psychiatric disorders such as depression, bipolar disorder, schizophrenia and schizoaffective disorder.

The effect of intravenous and inhalation anesthesia in general on the cognition of elderly patients undergoing non-cardiac surgery: a systematic review and meta-analysis

open access: yesFrontiers in Medicine, 2023
BackgroundPostoperative cognitive dysfunction (POCD) is a postoperative complication that often occurs in the elderly. This systematic review and meta-analysis aimed to compare intravenous anesthetics (propofol) with inhalation anesthetics (sevoflurane ...

A mini-review of the effects of inhalational and intravenous anesthetics on oxidative stress in dogs

open access: yesFrontiers in Veterinary Science, 2022
General anesthesia increases the production of reactive oxygen species (ROS), which can exacerbate or increase oxidative stress and thus affect the prognosis of surgical procedures.

Stabilizing membrane domains antagonizes n-alcohol anesthesia [PDF]

open access: yesBiophysical Journal, Volume 111, Issue 3, 9 August 2016, Pages 537-545, 2016
Diverse molecules induce general anesthesia with potency strongly correlated both with their hydrophobicity and their effects on certain ion channels. We recently observed that several n-alcohol anesthetics inhibit heterogeneity in plasma membrane derived vesicles by lowering the critical temperature ($T_c$) for phase separation.

Liquid general anesthetics lower critical temperatures in plasma membrane vesicles [PDF]

open access: yes, 2013
A large and diverse array of small hydrophobic molecules induce general anesthesia. Their efficacy as anesthetics has been shown to correlate both with their affinity for a hydrophobic environment and with their potency in inhibiting certain ligand gated ion channels.
