Hybrid Deep Neural Network for Brachial Plexus Nerve Segmentation in Ultrasound Images [PDF]
, 2021 Ultrasound-guided regional anesthesia (UGRA) can replace general anesthesia (GA), improving pain control and recovery time. This method can be applied on the brachial plexus (BP) after clavicular surgeries. However, identification of the BP from ultrasound (US) images is difficult, even for trained professionals.

Pharmacokinetic/Pharmacodynamic Anesthesia Model Incorporating psi-Caputo Fractional Derivatives [PDF]
Computers in Biology and Medicine 167 (2023), Art. 107679, 9 pp, 2023 We present a novel Pharmacokinetic/Pharmacodynamic (PK/PD) model for the induction phase of anesthesia, incorporating the $\psi$-Caputo fractional derivative. By employing the Picard iterative process, we derive a solution for a nonhomogeneous $\psi$-Caputo fractional system to characterize the dynamical behavior of the drugs distribution within a ...

General anesthesia reduces complexity and temporal asymmetry of the informational structures derived from neural recordings in Drosophila [PDF]
Phys. Rev. Research 2, 023219 (2020), 2019 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).

Regional Anesthesia: Advantages of Combined Use with General Anesthesia and Useful Tips for Improving Nerve Block Technique with Ultrasound Technology [PDF]
, 2017 Regional anesthesia is not always performed independently, but rather is frequently employed as part of a general anesthesia technique. Thus, its procedures and usefulness should be considered in settings where general anesthesia is used. In this chapter,

Nerve Block Target Localization and Needle Guidance for Autonomous Robotic Ultrasound Guided Regional Anesthesia [PDF]
arXiv, 2023 Visual servoing for the development of autonomous robotic systems capable of administering UltraSound (US) guided regional anesthesia requires real-time segmentation of nerves, needle tip localization and needle trajectory extrapolation. First, we recruited 227 patients to build a large dataset of 41,000 anesthesiologist annotated images from US videos

Macaque's Cortical Functional Connectivity Dynamics at the Onset of Propofol-Induced Anesthesia [PDF]
arXiv, 2021 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 ...

Regional Anesthesia for Hand Surgeries [PDF]
, 2018 Anesthesia for hand surgeries is one of the domains of regional anesthesia, where it plays the role, not only as a viable alternative to GA but also as an adjunct to it.
