Intra-Arterial Lidocaine Blunts the Trigeminocardiac Reflex during Endovascular Treatment of a Carotid-Cavernous Fistula. [PDF]

Case Rep Anesthesiol, 2021
Carotid-cavernous fistulas (CCFs) are vascular shunts that allow blood to flow from the carotid artery or its branches into the cavernous sinus. Endovascular embolization is the treatment modality of choice. The trigeminocardiac reflex (TCR) is a vagally

Coronary Spasm in Neurosurgical Patients and Role of Trigeminocardiac Reflex [PDF]

Neurology Research International, 2014
Background. Coronary artery spasm (CAS) is a rarely reported complication in neurosurgical patients and its main causative mechanism was attributed to vagal mediated responses. However, these may be the unusual manifestations of trigeminal cardiac reflex

The protective role of lidocaine in surgeries involving trigeminal nerve manipulation: a meta-analysis of trigeminocardiac reflex prevention. [PDF]

Neurosurg Rev
The trigeminocardiac reflex (TCR) is activated when the trigeminal nerve is manipulated through mechanical pressure, traction, or irritation. This leads to a rapid increase in parasympathetic activity, resulting in a decrease in heart rate (HR) and blood

A case report: A patient rescued by VA-ECMO after cardiac arrest triggered by trigeminocardiac reflex after nasal surgery. [PDF]

Medicine (Baltimore), 2023
Rationale: Cardiac arrest (CA) caused by trigeminocardiac reflex (TCR) after endoscopic nasal surgery is rare. Hence, when a patient suffers from TCR induced CA in the recovery room, most doctors may not be able to find the cause in a short time, and ...

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

, 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.

Definition and Diagnosis of the Trigeminocardiac Reflex: A Grounded Theory Approach for an Update. [PDF]

Front Neurol, 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.

[Delayed trigeminocardiac reflex after maxillofacial surgery: case report]. [PDF]

Braz J Anesthesiol, 2019
Background: Trigeminocardiac reflex is a physiological phenomenon that may occur in head and neck surgery, and is usually benign. However, it may present with exaggerated responses with severe morbidity.

The trigeminocardiac reflex - a comparison with the diving reflex in humans. [PDF]

Arch Med Sci, 2015
The trigeminocardiac reflex (TCR) has previously been described in the literature as a reflexive response of bradycardia, hypotension, and gastric hypermotility seen upon mechanical stimulation in the distribution of the trigeminal nerve. The diving reflex (DR) in humans is characterized by breath-holding, slowing of the heart rate, reduction of limb ...

Brain and heart connections: The trigeminocardiac reflex! [PDF]

Journal of Neuroanaesthesiology and Critical Care, 2017
AbstractTrigeminocardiac 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 peripheral distribution to the central nucleus.
