Limitations of the use of pressure waves to verify correct epidural needle position in dogs [PDF]

, 2013
The use of pressure waves to confirm the correct position of the epidural needle has been described in several domestic species and proposed as a valid alternative to standard methods, namely, control radiographic exam and fluoroscopy. The object of this

The Awakening Brain is Characterized by a Widespread and Spatiotemporally Heterogeneous Increase in High Frequencies

Advanced Science, EarlyView.
This work explores the process of morning awakening of the human brain using polysomnography paired with simultaneous stereo‐electroencephalography, a method that provides high spatial and temporal resolution for examining brain activity. Awakening is characterized by an increase in high‐frequency spectral power and connectivity.

A case of longitudinally extensive transverse myelitis with an isolated pontine lesion following epidural and spinal anesthesia for cesarean section

eNeurologicalSci, 2020
Severe neurologic complications following epidural and spinal anesthesia rarely occur. Transverse myelitis has been reported as a rare complication of epidural or spinal anesthesia.

Needle guidance with Doppler-tracked polarization-sensitive optical coherence tomography [PDF]

arXiv, 2023
We demonstrate that a simple, unscanned polarization-sensitive optical coherence tomography needle probe can be used to perform layer identification in biological tissues. Broadband light from a laser centered at 1310 nm was sent through a fiber that was embedded into a needle, and analysis of the polarization state of the returning light after ...

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

, 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.

Deciphering Auditory Hyperexcitability in Otogl Mutant Mice Unravels an Auditory Neuropathy Mechanism

Advanced Science, EarlyView.
By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear

Simultaneous Brachial Plexus Block and Combined Two-Segment Spinal-Epidural Anesthesia with Fixation of an Epidural Catheter in the Subcutaneous Canal in a Patient with Polytrauma

Неотложная медицинская помощь, 2021
The article reports an example of the simultaneous use of brachial plexus block and combined two-segment spinal-epidural anesthesia with fixation of an epidural catheter in the subcutaneous canal in an 81-year-old patient after receiving a household ...

Reduced neural activity during volatile anesthesia compared to TIVA: evidence from a novel EEG signal processing analysis [PDF]

arXiv, 2020
Post-operative cognitive decline is a well-known phenomenon and of crucial importance especially in the elderly. General anesthesia can be accomplished by inhalation-based (volatile) or total intravenous anesthesia (TIVA). While their effects on post-operative symptoms have been investigated, little is known about their influence on brain ...

Stabilizing membrane domains antagonizes n-alcohol anesthesia [PDF]

Biophysical 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.
