Mechanisms of General Anesthesia [PDF]

open access: yesEnvironmental Health Perspectives, 1990
Although general anesthetics are often said to be nonspecific agents, it is likely that they act at a much more restricted set of target sites than commonly believed. The traditional view has been that the primary targets are lipid portions of nerve membranes, but recent evidence shows that the effects on lipid bilayers of clinically relevant levels of

Dental treatment under general anesthesia for patients with severe disabilities

open access: yesJournal of dental anesthesia and pain medicine, 2021
Patients with disabilities have difficulties tolerating in-office dental treatment due to limitations relating to cooperation and/or physical problems. Therefore, they often require general anesthesia or sedation to facilitate safe treatment.

The association between gut microbiota and postoperative delirium in patients

open access: yesTranslational Psychiatry, 2023
Postoperative delirium is a common postoperative complication in older patients, and its pathogenesis and biomarkers remain largely undetermined. The gut microbiota has been shown to regulate brain function, and therefore, it is vital to explore the ...

Neural Substrates for the Regulation of Sleep and General Anesthesia

open access: yesCurrent Neuropharmacology, 2021
General anesthesia has been successfully used in clinics for over 170 years, but its mechanisms of effect remain unclear. Behaviorally, general anesthesia is similar to sleep as it produces a reversible transition between wakefulness and the state of ...

Propofol Induction Reduces the Capacity for Neural Information Integration: Implications for the Mechanism of Consciousness and General Anesthesia [PDF]

open access: yes, 2008
The cognitive unbinding paradigm suggests that the synthesis of cognitive information is attenuated by general anesthesia. Here, we investigated the functional organization of brain activities in the conscious and anesthetized states, based on ...

Cognitive dysfunction following desflurane versus sevoflurane general anesthesia in elderly patients: a randomized controlled trial. [PDF]

open access: yes, 2014
UnlabelledAs life expectancy increases, more patients ≥65 years undergo general anesthesia. Anesthetic agents may contribute to postoperative cognitive dysfunction, and incidence may differ with anesthetic agents or intraoperative anesthesia depth ...

General anesthesia does not have persistent effects on attention in rodents [PDF]

open access: yes, 2019
Background: Studies in animals have shown that general anesthesia can cause persistent spatial memory impairment, but the influence of anesthetics on other cognitive functions is unclear.

Sleep and general anesthesia [PDF]

open access: yesCanadian Journal of Anesthesia/Journal canadien d'anesthésie, 2010
The mechanisms through which general anesthetics cause reversible loss of consciousness are characterized poorly. In this review, we examine the evidence that anesthetic-induced loss of consciousness may be caused by actions on the neuronal pathways that produce natural sleep.It is clear that many general anesthetics produce effects in the brain ...

Anesthetic management of inguinal hernia in an ex-premature infant with subglottic stenosis: a case report

open access: yesJA Clinical Reports, 2023
Background We report the anesthetic management of inguinal hernia repair for an infant with subglottic stenosis. A previously scheduled operation had been cancelled due to unexpected airway trouble during the induction.

Cardiovascular changes after administration of aerosolized salbutamol in horses: five cases [PDF]

open access: yes, 2014
Prevention and treatment of intraoperative hypoxemia in horses is difficult and both efficacy and safety of therapeutic maneuvers have to be taken into account.
