- Primary Outcome Measures
Name Time Method To observe corelation between peak blood flow velocity variation in the internal carotid artery measured on transfontanelle ultrasound with the respiratory variability of peak aortic blood flow velocity on transthoracic echocardiography, as a marker of fluid responsiveness in infants on mechanical ventilation after cardiac surgeryTimepoint: one hour and six hour after cardiac surgery
- Secondary Outcome Measures
Name Time Method Toassess if the internal carotid artery peak blood flow variability corresponds to the change in central venous pressure, change in inferior vena cava diameter and plethysmographic variability index.Timepoint: One hour and six hours after surgery
