Effects of Dexmedetomidine on Cardiac Electrophysiology in Patients Under General Anesthesia During Perioperative Period

Summary

Perioperative stress may increase the incidence of adverse events in the cardiovascular system and lead to poor prognosis. Dexmedetomidine is a highly selective α2 adrenergic receptor agonist, which can inhibit stress response and reduce hemodynamic fluctuations. In different usage plans, dexmedetomidine can have different effects on hemodynamics, myocardial electrical activity, cardiac function. The main purpose was to observe its effects on myocardial electrophysiology and cardiac function during perioperative period. The secondary purpose was to explore the optimal dose of dexmedetomidine that has the least adverse effects on perioperative electrocardia action and cardiac function
