BackgroundVolatile anesthetics including sevoflurane and isoflurane enhance oscillations of cortical electroencephalogram (EEG), partly by their modulations on glutamate-mediated excitatory synaptic transmission. Expression of NMDA receptors is increased

Macaque's Cortical Functional Connectivity Dynamics at the Onset of Propofol-Induced Anesthesia [PDF]
Propofol, when administered for general anesthesia, induces oscillatory dynamic brain states that are thought to underlie the drug's pharmacological effects. Despite the elucidation of propofol's mechanisms of action at the molecular level, its effects on neural circuits and overall cortical functioning, which eventually lead to unconsciousness, are ...

Ropivacaine as the drug of choice for regional anesthesia: why so?
While writing the article, we analyzed all the studies related to ropivacaine for the first half of 2021, which were published in PubMed. Previous review articles on ropivacaine were also analyzed.

Long-term functional patency and cost-effectiveness of arteriovenous fistula creation under regional anesthesia: a randomized controlled trial [PDF]
BACKGROUND:Regional anesthesia improves short-term blood flow through arteriovenous fistulas (AVFs). We previously demonstrated that, compared with local anesthesia, regional anesthesia improves primary AVF patency at 3 months.

INTRAVENOUS LOCAL ANESTHESIA [PDF]
In searching for a method to avoid the difficulties of nerve-blocking anesthesia, Bier 1 developed the idea of Venenanasthesie which he reported at the thirty-seventh German Surgical Congress, in 1908. In 1909, he reported a series of 134 cases and gave in detail the technic of the method. 2 The anesthetizing solution is injected into the veins, in a

Immediate reaction to lidocaine with periorbital edema during upper blepharoplasty [PDF]
Introduction: Blepharoplasty is the fourth most commonly performed cosmetic surgery in the US, with 207,000 operations in 2014. Lidocaine is the preferred anesthetic agent for blepharoplasty.

Automatic Ultrasound Image Segmentation of Supraclavicular Nerve Using Dilated U-Net Deep Learning Architecture [PDF]
Automated object recognition in medical images can facilitate medical diagnosis and treatment. In this paper, we automatically segmented supraclavicular nerves in ultrasound images to assist in injecting peripheral nerve blocks. Nerve blocks are generally used for pain treatment after surgery, where ultrasound guidance is used to inject local ...

General anesthesia reduces complexity and temporal asymmetry of the informational structures derived from neural recordings in Drosophila [PDF]
We apply techniques from the field of computational mechanics to evaluate the statistical complexity of neural recording data from fruit flies. First, we connect statistical complexity to the flies' level of conscious arousal, which is manipulated by general anesthesia (isoflurane).
