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

Intra-Arterial Lidocaine Blunts the Trigeminocardiac Reflex during Endovascular Treatment of a Carotid-Cavernous Fistula [PDF]
Case Reports in Anesthesiology, 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

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

Repeated ventricular bigeminy by trigeminocardiac reflex despite atropine administration during superficial upper lip surgery: A case report. [PDF]
World J Clin Cases, 2022 BACKGROUND The trigeminocardiac reflex (TCR) is usually caused by an increased parasympathetic tone when pressure or traction is applied to the surrounding tissue of the trigeminal nerve.

The Trigeminocardiac Reflex? Severe Bradycardia Secondary to Facial Trauma: A Case Report [PDF]
Clinical Practice and Cases in Emergency MedicineIntroduction: The trigeminocardiac reflex (TCR), a physiologic response to irritation of the branches of the trigeminal nerve, was first described in humans in 1870. Gastric hypermotility, hypotension, bradycardia, and even asystole have been reported in

Prophylactic intra-arterial injection of lidocaine: a novel strategy to prevent endovascular embolization-induced trigeminocardiac reflex. [PDF]
J Neurointerv Surg, 2023 Background Trigeminocardiac reflex (TCR) is a brainstem reflex that can lead to hemodynamic instability manifested as bradycardia, decrease/increase of mean arterial pressure (MAP) and, in the worst case scenario, asystole during surgery.

Trigeminocardiac reflex during maxillary third molar extraction: Our experience. [PDF]
Natl J Maxillofac Surg, 2022 Trigeminocardiac reflex (TCR) is a cascade of physiological response secondary to the stimulation of any of the sensory divisions of the trigeminal nerve, which is the largest cranial nerve and provides sensory supply to the face, scalp, mucosa of the ...

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