Trial summary

Fluid overload increases morbidity and mortality of pediatrics patients in intensive care unit (ICU). It could be interesting to predict the decrease in stroke volume when diuretics are prescribed. Nevertheless, no test predict a decrease of stroke volume in a context of a diuretics induced depletion. Read more about this study

About this study

Fluid overload increases morbidity and mortality of pediatrics patients in intensive care unit (ICU). It could be interesting to predict the decrease in stroke volume when diuretics are prescribed. Nevertheless, no test predict a decrease of stroke volume in a context of a diuretics induced depletion. Abdominal compression (AC) coupled with echocardiographic measurement of the stroke volume can predict fluid responsiveness and is a good tool to assess preload dependency. Another point is that during depletion refilling can occur. We aim to assess the diagnostic accuracy of abdominal compression to predict a decrease of the stroke volume of 15 % during diuretic-induced depletion of 10 ml/kg of diuresis. Secondary outcome will assess the hemoconcentration during depletion to diagnose a decrease of stroke volume during diuretic induced depletion

Read the detailed description

Fluid overload increases morbidity and mortality of pediatrics patients in intensive care unit (ICU). The pediatric intensivist has a priority to decrease unnecessary fluid load and to make the fluid balance negative in case of fluid overload. Diuretics help to make the fluid balance negative but can lead to a reduction of volemia that can lead to hypovolemia. Hypovolemia can induce a reduction of stroke volume and cardiac index that can alter tissue perfusion and increase organ dysfunction.

It could be interesting to predict the decrease in stroke volume when diuretics are prescribed. Nevertheless, no test predict a decrease of stroke volume in a context of a diuretics induced depletion.

The concept of preload dependency described by frank-starling is interesting in that context.

Preload dependency is a state of the working heart characterized by a modification of stroke volume when a modification of preload is done. Conversely, no preload dependency is a state of the working heart characterized by no modification of stroke volume when a modification of preload is done.

If the heart is in a state of preload dependency, a reduction of preload induced by diuretics depletion might induce a reduction of stroke volume. Conversely, if the heart is in a state of no preload dependency a reduction of preload induced by a diuretics depletion might not induce a reduction of stroke volume Abdominal compression coupled with echocardiographic measurement of the stroke volume can predict fluid responsiveness and is a good tool to assess preload dependency.

Another point is that during depletion refilling can occur. Studies performed during hemodialysis have shown that refilling maintains a stable hematocrit during depletion. the absence of refilling is characterized by an hemoconcentration

We aim to assess the diagnostic accuracy of abdominal compression to predict a decrease of the stroke volume of 15 % during diuretic induced depletion of 10ml/kg of diuresis. Secondary outcome will assess the hemoconcentration during depletion to diagnose a decrease of stroke volume during diuretic induced depletion

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Abdominal compression (AC)Diagnostic test

    Also called Echocardiographic assessement of volume status

    An echocardiography with stroke volume measurement coupled with an abdominal compression will be performed before and after ta diuretics induced diuresis of 10ml/kg in pediatric patients hospitalized in a pediatric intensive care unit (PICU) diagnosed with fluid overload

  • blood sampleDiagnostic test

    proteinemia and hematocrit will be measured before and after a diuretics induced diuresis of 10ml/kg

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Stroke volume index (SVi) variation induced by abdominal compression ΔSVi-AC

    Variation of stroke volume index measured with echocardiography induced by abdominal compression. We will test if stroke volume index variation during abdominal compression can predict a decrease of 15 % of the stroke volume during a 10 ml/kg diuresis induced by diuretics administration.

    Measured: 2 hours

Secondary outcomes (4)
  1. Hemoconcentration with protides

    proteinemia variation. We will test if proteinemia variation can predict a diagnose a reduction of 15 % of the stroke volume during a 10 ml/kg diuresis induced by diuretics administration.

    Measured: 2 hours

  2. Hemoconcentration with hematocrit

    Hematocrit variation. We will test if hematocrit variation can predict a diagnose a reduction of 15 % of the stroke volume during a 10 ml/kg diuresis induced by diuretics administration.

    Measured: 2 hours

  3. Respiratory variation of the maximum aortic velocity of the left ventricular outflow tractΔVpeak

    Variation of the maximum velocity of the left ventricular outflow tract induced by ventilation. We will test if ΔVpeak can predict a decrease of 15 % of the stroke volume during a 10 ml/kg diuresis induced by diuretics administration.

    Measured: 2 hours

  4. Respiratory variation of the inferior vena cava diameter ΔIVC

    Variation of inferior vena cava diameter induced by ventilation. We will test if ΔIVC can predict a decrease of 15 % of the stroke volume during a 10 ml/kg diuresis induced by diuretics administration.

    Measured: 2 hours
