The protective role of lidocaine in surgeries involving trigeminal nerve manipulation: a meta-analysis of trigeminocardiac reflex prevention حسب Almonzer Al-Qiami (22393303)

"…<p dir="ltr">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 pressure, which can potentially lead to bradycardia, and cardiac arrest, with a prevalence of 14.5% during neurointerventional procedures (8). …"
