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

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.

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

Cardiac Emergencies in Neurosurgical Patients [PDF]

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
Perioperative safety concerns are a major area of interest in recent years. Severe cardiac perturbation such as cardiac arrest is one of the most dreaded complications in the intraoperative period; however, little is known about the management of these ...

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

Trigeminocardiac reflex in bimaxillary orthognathic surgery: case review. [PDF]

Med Oral Patol Oral Cir Bucal
The trigeminocardiac reflex (TCR) is a rare but clinically significant phenomenon characterized by bradycardia, hypotension, or asystole triggered by trigeminal nerve stimulation during maxillofacial surgery. It necessitates prompt recognition and management to ensure patient safety.

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.

Cerebral Hemodynamic Changes during the Trigeminocardiac Reflex: Description of a New Animal Model Protocol

The Scientific World Journal, 2010
The trigeminocardiac reflex (TCR) is a well-known brainstem reflex, first described in skull base and neurosurgery by the senior author in 1999, leading to reflex apnea, bradycardia, and changes of mean arterial pressure.

Prevention of trigeminocardiac reflex-induced severe bradycardia during cerebral aneurysm clipping surgery by topical anesthesia of the dura surface and atropine administration: a case report. [PDF]

JA Clin Rep, 2022
Background Trigeminocardiac reflex (TCR) by stimulation of the sensory branch of the trigeminal nerve induces transient bradycardia and hypotension. We report a case in which light mechanical stimulation to the dura mater during brain surgery induced ...
