NCT07099664

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Aortic VTI variation (%) measured by suprasternal doppler in percent of mean aortic VTI.

    During preoperative, after induction and fasting compensation, before incision.

Secondary Outcomes (3)

  • Proportion of patient (%) in whom we can use suprasternal aortic measurements.

    During preoperative period, after induction and fasting compensation, before incision.

  • Optimal threshold of aortic VTI variation (%) measured by suprasternal doppler to determine wether the patient is preload dependant or independent as defined above.

    During preoperative period, after induction and fasting compensation, before incision.

  • Correlation between : - fasting duration in hours, determined by patient or parent interrogation. - preload dependence as defined above. More than one outcome measure appears to be described.

    During preoperative period, after induction and fasting compensation, before incision.

Study Arms (1)

Measurement of VTI variation and cardiac output after general anaesthesia.

Measurement of VTI variation and cardiac output after general anaesthesia. Patients responding to volume expansion (more than 10% increase of cardiac output measured by transthoracic ultrasound after a 10ml/kg perfusion of cristalloids)

Diagnostic Test: Measurement of aortic Vmax and VTI with suprasternal doppler.

Interventions

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.

Measurement of VTI variation and cardiac output after general anaesthesia.
