Haemodynamic responses following orotracheal intubation in patients with hypertension---Macintosh direct laryngoscope versus Glidescope®videolaryngoscope

Indian Journal of Anaesthesia, 2021
Background and Aims: Glidescope®videolaryngoscope (GVL) is a video intubation system with 60° angle blade that provides excellent laryngeal view, does not require alignment of oral, pharyngeal, and laryngeal axes for visualisation of glottis, thus ...

Response-mode decomposition of spatio-temporal haemodynamics [PDF]

Journal of The Royal Society Interface, 2016
The blood oxygen-level dependent (BOLD) response to a neural stimulus is analysed using the transfer function derived from a physiologically based poroelastic model of cortical tissue. The transfer function is decomposed into components that correspond to distinct poles, each related to a response mode with a natural frequency and dispersion relation ...

Attenuation of the haemodynamic responses to tracheal intubation with gabapentin, fentanyl and a combination of both: A randomised controlled trial

Indian Journal of Anaesthesia, 2015
Background and Aims: We conducted a prospective, randomised, double-blind, controlled clinical trial to examine (1) whether a single preoperative dose of 800 mg gabapentin would be as effective as 2 μg/kg of intravenous (IV) fentanyl in blunting the ...

Emotional modulation of visual cortex activity: A functional nearinfrared spectroscopy study [PDF]

, 2009
Functional neuroimaging and electroencephalography reveal emotional effects in early visual cortex. Here, we used fNIRS to examine haemodynamic responses evoked by neutral, positive and negative emotional pictures, matched for brightness, contrast, hue,

Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa [PDF]

, 2011
Cortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in

Multimodal imaging of human brain activity: rational, biophysical aspects and modes of integration [PDF]

, 2009
Until relatively recently the vast majority of imaging and electrophysiological studies of human brain activity have relied on single-modality measurements usually correlated with readily observable or experimentally modified behavioural or brain state ...

Age-related changes in global motion coherence: conflicting haemodynamic and perceptual responses [PDF]

, 2018
Our aim was to use both behavioural and neuroimaging data to identify indicators of perceptual decline in motion processing. We employed a global motion coherence task and functional Near Infrared Spectroscopy (fNIRS). Healthy adults (n = 72, 18-85) were

Comparison of Gabapentin and Esmolol in Reducing Haemodynamic Response to Laryngoscopy and Intubation: A Randomised Clinical Trial [PDF]

Journal of Clinical and Diagnostic Research, 2023
Introduction: Haemodynamic stress response to direct laryngoscopy and endotracheal intubation have been well established. Both gabapentin and esmolol facilitates in attenuating this stress response through different mechanisms.
