Definition and Diagnosis of the Trigeminocardiac Reflex: A Grounded Theory Approach for an Update

open access: yesFrontiers in Neurology, 2017
BackgroundThe trigeminocardiac reflex (TCR) is defined as sudden onset of parasympathetic dysrhythmias including hemodynamic irregularities, apnea, and gastric hypermotility during stimulation of sensory branches of the trigeminal nerve.

Trigeminocardiac reflex by mandibular extension on rat pial microcirculation: Role of nitric oxide [PDF]

open access: yes, 2014
In the present study we have extended our previous findings about the effects of 10 minutes of passive mandibular extension in anesthetized Wistar rats. By prolonging the observation time to 3 hours, we showed that 10 minutes mandibular extension caused ...

Abstract 1122‐000193: Intracranial Bleeding in a Juvenile Nasopharyngeal Angiofibroma Stage IVb

open access: yesStroke: Vascular and Interventional Neurology, 2021
Introduction: The trigeminocardiac reflex has been reported in craniofacial, neurosurgery, ophthalmological surgeries, and recently at endovascular procedures. Therefore, it has been called by other names also as trigeminal depressor reflex, reflex vagal

Anesthetic Considerations in a Patient with Large Cavernous Carotid Aneurysm

open access: yesJournal of Neuroanaesthesiology and Critical Care, 2023
Cavernous carotid aneurysms (CCA) are a rare form of intracranial aneurysms. Patients undergoing clipping of a large unruptured CCA pose multiple anesthetic concerns including intraoperative trigeminocardiac reflex (TCR).

Prognostic factors for trigeminocardiac reflex during cerebrovascular intervention operation

open access: yesFrontiers in Surgery, 2022
IntroductionTrigeminocardiac reflex (TCR) is a brainstem reflexive response of hemodynamic instability during surgery. Identification of risk factors relevant to TCR during cerebrovascular intervention procedures is helpful to efficiently prevent and ...

Brain and heart connections: The trigeminocardiac reflex!

open access: yesJournal of Neuroanaesthesiology and Critical Care, 2017
Trigeminocardiac reflex (TCR) is a well-established neurogenic reflex although its exact mechanism and clinical significance remain unclear. This reflex may be incited by stimulation of the trigeminal nerve anywhere along its course starting from the ...

Diving in the Arctic: Cold Water Immersion’s Effects on Heart Rate Variability in Navy Divers [PDF]

open access: yes, 2020
Introduction Diving close to the Arctic circle means diving in cold water regardless of the time of year. The human body reacts to cold through autonomous nervous system (ANS)-mediated thermoregulatory mechanisms.

The Trigeminocardiac Reflex — An Example of Reflexive Heart Rhythm Change [PDF]

open access: yes, 2015
The trigeminocardiac reflex (TCR) is defined as the sudden onset of parasympathetic dysrhythmia, sympathetic hypotension, apnoea or gastric hyper-motility during mechanical/thermal stimulation of any of the sensory branches of the trigeminal nerve.
