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

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

Comparison of Remimazolam and Propofol for Intravenous Anesthesia on Trigeminocardiac Reflex in Percutaneous Balloon Compression for Trigeminal Neuralgia: A Randomized Controlled Trial [PDF]

Drug Des Devel Ther
Background Trigeminal neuralgia usually presents as incapacitating facial pain. Percutaneous balloon compression (PBC) is frequently utilized to manage this ailment.

Evaluation of Trigeminocardiac Reflex in Patients Undergoing Elevation of Zygomatic Fractures. [PDF]

Cureus, 2022
Aim Trigeminocardiac reflex (TCR) manifests as typical hemodynamic perturbations including a sudden lowering of heart rate, mean arterial blood pressure (MABP), cardiac arrhythmias, and asystole.

Case Report: Trigeminocardiac Reflex in Endovascular Recanalization of Intracranial Internal Carotid Artery Occlusion. [PDF]

Front Neurol, 2022
Background The trigeminocardiac reflex (TCR) is a unique brainstem reflex that manifests as sudden negative hemodynamic changes. Although rare, TCR may develop during interventional neuroradiology procedures.

Atypical trigeminocardiac reflex during intranasal dexmedetomidine sedation of a 6-month-old premature baby. [PDF]

BMJ Case Rep, 2022
The trigeminocardiac reflex (TCR) is an established brainstem reflex leading to parasympathetic dysrhythmias—including haemodynamic irregularities, apnoea and gastric hypermotility—during stimulation of any sensory branches of the trigeminal nerve.

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.

Torsade de pointes during an oral surgery caused by a combination of herbal medicine-induced pseudoaldosteronism and trigeminocardiac reflex. [PDF]

Oxf Med Case Reports, 2023
Licorice can cause pseudoaldosteronism and QT prolongation as its side effect. Trigeminal nerve stimulation, including surgical intervention involving the face, can cause transient bradycardia, known as the trigeminocardiac reflex.

A near catastrophe from trigeminocardiac reflex [PDF]

Journal of Neuroanaesthesiology and Critical Care, 2017
Trigeminocardiac reflex is a brainstem reflex that results from stimulation of any branch of the trigeminal nerve along its course. It produces a constellation of signs and symptoms decrease in blood pressure (BP) and heart rate, dysrhythmias, apnoea and

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

Frontiers 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.
