Comparative Study of Atropine Combined with Sodium Nitroprusside Pretreatment to Prevent Trigemino Cardiac Reflex after Trigeminal Ganglion Compression.

Introduction: Manipulation of percutaneous compression of the trigeminal ganglion (PCTG) for trigeminal neuralgia (TN) can lead to significant haemodynamic changes, which were termed trigemino cardiac reflex (TCR). Nevertheless, many studies indicated that atropine pretreatment can reduce the incidence of bradycardia and cardiac arrest, but do not take precautions against abrupt rise of blood pressure.

Aim: The purpose of our study was to compare control group {patients receiving Sodium Nitro-Prusside (SNP) pretreatment before PCTG} with study groups (patients receiving different doses of atropine combined with SNP pretreatment before PCTG) in cardiovascular parameters {Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR)} at 5 periods during Total Intravenous Anaesthesia (TIVA).

Comparative study of trigeminocardiac reflex after trigeminal ganglion compression during total intravenous anesthesia.

Background: Percutaneous compression of the trigeminal ganglion (PCTG) is an alternative surgical treatment for trigeminal neuralgia (TN). Manipulation of PCTG can lead to significant hemodynamic changes, which may increase the risk of cardiovascular complications. However, to our knowledge, few studies have focused on anesthesia experience during PCTG as treatment for TN so far.
