Brief summary
The purpose of this study is to evaluate whether carotid Doppler peak systolic velocity can be an easy to measure possible surrogate for echocardiographic measurement of aortic peak systolic velocity variation which is an index of fluid responsiveness in mechanically ventilated children intra-operatively.
Interventions
Aortic peak systolic velocity variation to be measured by echocardiography from apical five chamber and suprasternal windows alongwith carotid peak systolic velocity variation by Doppler ultrasound simultaneously at intermittent time points intermittently.
