Summary

After major surgery, fluid overload is associated with an increase of morbidity and mortality. Fluid administration should therefore be given wisely. However, there is a paucity of monitor to predict preload dependence in paediatric anaesthesia. The aim of this study is to determine if VTI variation, measured through the suprasternal window, with a cardiac doppler probe, can predict preload dependence. Indeed, cardiac probe are present in most operating room and suprasternal window is reachable in most surgical case, which should allow VTI monitoring for the vast majority of our patient.

Type	Name	Description
DIAGNOSTIC_TEST	Measurement of aortic Vmax and VTI with suprasternal doppler.	Measurement of aortic Vmax and VTI with suprasternal doppler. Measurement of VTI variation and cardiac output after general anaesthesia. After preoperative fasting compensation, measurement of cardiac output (CO). Search of a difference in the suprasternale VTI variability between the patients who have increased their CO after fasting compensation and the patient who haven't.
