Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
