Impact of dexmedetomidine on hemodynamics in rabbits

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To evaluate the effects of single intravenous administration of Dexmedetomidine (DEX) on hemodynamics in rabbits. Methods: A total of 32 New Zealand white rabbits were randomly divided into the control group (Group C), Group D1 (2.75 μg/kg), Group D2 (5.5 μg/kg), and Group ...

Predictors of outcomes after correction of acute type a aortic dissection under moderate hypothermic circulatory arrest and antegrade cerebral perfusion

Abstract Introduction: Hypothermic circulatory arrest is widely used for correction of acute type A aortic dissection pathology. We present our experience of 45 consecutive patients operated in our unit with bilateral antegrade cerebral perfusion and moderate hypothermic circulatory arrest. Methods: Be...

An Alternative Method to Calculate Simplified Projected Aortic Valve Area at Normal Flow Rate

Arq. bras. cardiol; 110 (2), 2018
Abstract Background: Simplified projected aortic valve area (EOAproj) is a valuable echocardiographic parameter in the evaluation of low flow low gradient aortic stenosis (LFLG AS). Its widespread use in clinical practice is hampered by the laborious process of flow rate (Q) calculation. Objetive: This...
