Trigeminal Cardiac Reflex

Trigeminal Cardiac Reflex and Cerebral Blood Flow Regulation

The stimulation of some facial regions is known to trigger the trigemino-cardiac reflex: the main stimulus is represented by the contact of the face with water. This phenomenon called diving reflex induces a set of reactions in the cardiovascular and respiratory systems occurring in all mammals, especially marine (whales, seals). During the immersion of the face in the water, the main responses...

Trigeminal Cardiac Reflex: New Thinking Model About the Definition Based on a Literature Review

Trigeminocardiac reflex (TCR) is a brainstem reflex that manifests as sudden onset of hemodynamic perturbation in blood pressure (MABP) and heart rate (HR), as apnea and as gastric hypermotility during stimulation of any branches of the trigeminal nerve. The molecular and clinical knowledge about the TCR is in a constant growth since 1999, what implies a current need of a review about its defin...

Trigeminal Cardiac Reflex Caused by Onyx Embolization of Intracranial Dural Arteriovenous Fistula.

Trigeminocardiac reflex (TCR) is a reflexive response of bradycardia, hypotension and gastric hypermotility which is observed upon mechanical stimulation in the distribution of the trigeminal nerve. Previous articles have described TCR during intracranial operations, ophthalmic surgery, microcompression of the trigeminal ganglion and radiofrequency lesioning of the trigeminal ganglion. TCR may ...

Is prevention or knowledge better than a cure for the trigeminal cardiac reflex?

oculo-cardiac reflex during strabismus surgery

purpose: to evaluate the incidence of the oculo-cardiac reflex (ocr) and its associated risk factors during strabismus surgeries performed at a tertiary referral center between 1390 and 1392. methods: over a 2-year period, all strabismus surgery candidates were enrolled in the study after obtaining consent from the patients or their parents. vital signs were recorded before the initiation of th...
