[Intravenous regional anesthesia].

open access: yesUgeskrift for laeger, 2003
Intravenous regional anesthesia (IVRA) is established by administration of local anesthetics in a vein on the extremity, isolated from the rest of the body by a pneumatic tourniquet. The local anesthetics act directly on the small nerve endings and on bigger nerves in the cubital fossa.

Characteristics of pulsed electric field cardiac ablation porcine treatment zones with a focal catheter

open access: yesJournal of Cardiovascular Electrophysiology, Volume 34, Issue 1, Page 99-107, January 2023., 2023
Abstract Objectives Pulsed electric field (PEF) therapies employ punctuated energy delivery to kill cells in a volume of tissue through mechanisms that are not dependent on thermal processes. A key component to successful cardiac ablation procedures is ensuring the generation of transmural, contiguous ablation zones, which requires in‐depth knowledge ...

Whole‐brain BOLD responses to graded hypoxic challenges at 7 T, 9.4 T, and 15.2 T: Implications for ultrahigh‐field functional and dynamic susceptibility contrast MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Blood oxygen–level dependent (BOLD) functional MRI signals depend on changes in deoxyhemoglobin content, which is associated with baseline cerebral blood volume (CBV) and blood oxygen saturation change. To accurately interpret activation‐induced BOLD responses and quantify perfusion values by BOLD dynamic susceptibility contrast (BOLD ...

Structure and Dynamics of Brain Lobe's Functional Networks at the Onset of Anesthesia-Induced Loss of Consciousness [PDF]

open access: yesarXiv, 2016
Anesthetic agents are neurotropic drugs capable of inducing significant alterations in the thalamocortical system, promoting a profound decrease in awareness and level of consciousness. There is experimental evidence that general anesthesia affects large-scale functional networks, leading to alterations in the brain's state.

Characterization of Large-Scale Functional Brain Networks During Ketamine-Medetomidine Anesthetic Induction [PDF]

open access: yesarXiv, 2016
Several experiments provide evidence that specialized brain regions functionally interact and reveal that the brain processes and integrates information in a specific and structured manner. Networks can be applied to model brain functional activities, providing means to characterize and quantify this structured form of organization.

A New Approach to Intravenous Regional Anesthesia

open access: yesAnesthesia & Analgesia, 1992
In an attempt to reduce the dose of local anesthetic during intravenous (IV) regional anesthesia of the upper limb, we combined 100 mg of lidocaine with 0.05 mg of fentanyl and 0.5 mg of pancuronium. The study was designed in a randomized, double-blind fashion to determine the efficacy of this approach in providing analgesia and relaxation during ...

Effects of Myroxylon pereirae, Phenytoin, and Clinoptilolite After Pharyngocutaneous Fistula: An Experimental Animal Model

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective The objective of this study was to conduct a comparative evaluation of the effects of Myroxylon pereirae (MP), phenytoin, and clinoptilolite on wound healing in an experimental animal model for the treatment of pharyngocutaneous fistula (PCF). Study Design Prospective controlled animal study. Setting Animal laboratory.

Deep learning with spatiotemporal consistency for nerve segmentation in ultrasound images [PDF]

open access: yesarXiv, 2017
Ultrasound-Guided Regional Anesthesia (UGRA) has been gaining importance in the last few years, offering numerous advantages over alternative methods of nerve localization (neurostimulation or paraesthesia). However, nerve detection is one of the most tasks that anaesthetists can encounter in the UGRA procedure.

Computed tomographic features of clinically suspected rhinitis in domestic rabbits (Oryctolagus cuniculus)

open access: yesVeterinary Record, EarlyView.
Abstract Background The aim of this study was to characterise the computed tomographic (CT) findings in domestic rabbits with clinically suspected rhinitis and compare them with CT findings in rabbits without clinical signs of rhinitis. Methods CT images of rabbits that underwent a CT of the head were retrospectively reviewed and any CT abnormalities ...
