Purpose: This review aims to summarize the complex nature of the trigeminocardiac reflex into a brief overview, focusing on its mechanism, anatomy, classification, manifestations, and treatment approaches.
Method: By examining the latest clinical studies and anatomical insights, we outline the neural pathways of trigeminocardiac reflex, identify subtypes on the basis of stimulation points, and describe the physiological responses it elicits.
Results: Trigeminocardiac reflex is a brainstem reflex characterized by symptoms, such as bradycardia, hypotension, hypertension, apnea, and gastric hypermotility. It has been reported in surgical procedures involving stimulation of sensory branches of the trigeminal nerve. Trigeminocardiac reflex management typically involves prophylactic measures to prevent intraoperative cardiovascular complications.
Conclusion: A comprehensive understanding of trigeminocardiac reflex mechanisms and subtypes is essential to anticipate and mitigate its effects during procedures that may trigger this reflex. This knowledge ensures patient well-being and optimizes surgical outcomes, highlighting the importance of continued research in this area.

This review emphasises the importance of the cardiovascular response to facial cooling (FC) and breath holding in both sexes. The trigemino-cardiac reflex, triggered by FC, reduces heart rate (HR) and constricts blood vessels. When combined with breath holding, this effect intensifies, enhancing the cardiodepressive impact.

Background: In recent years, β-blockers such as metoprolol have been upgraded to first-line antihypertensive drugs. However, metoprolol demonstrates poor prognosis effects on diseases such as stroke. Further clinical application may expand the possibility of its related adverse reactions.

Article Synopsis
- Trigeminal neuralgia causes severe facial pain, and percutaneous balloon compression (PBC) is a common treatment, though it can provoke trigeminocardiac reflex (TCR), resulting in heart complications.
- This study compares the effects of remimazolam and propofol anesthesia on the occurrence of TCR during PBC in patients with trigeminal neuralgia.
- Results showed that remimazolam significantly reduced the incidence of TCR and severe TCR compared to propofol, while also maintaining a higher heart rate, with no increase in adverse events.
