Transesophageal Echocardiographic Evaluation of the Effect of Dexmedetomidine Infusion as an Adjuvant to General Anesthesia on the Cardiac Function

• Status: Completed
• Trial end date: 2015-01-01

Summary

Dexmedetomidine is a selective alpha-2 adrenergic agonist that can be considered as an adjuvant to propofol or inhalational anesthetics. Dexmedetomidine mediate its cardiovascular effect through activation of receptors in central and peripheral nervous system. The classic cardiovascular response of dexmedetomidine is the biphasic with initial short-term increase in blood pressure followed by long-lasting decrease in BP and HR. There were several reports about these hemodynamic changes of dexmedetomidine, but not the evaluation of direct effects on cardiac function. The purpose of this study is to evaluate the effects of dexmedetomidine as an anesthetic adjuvant on cardiac function by using the transesophageal echocardiography.
