  • Child

Who may be able to join

  • 1-Patients from age of 1 month to 14 years old of both sexes.

About this study

The aim of the study is to detect wither dobutamine or milrinone have a privilege in the management of low cardiac output pediatric patients over the other.

Read the detailed description

Randomized controlled trials (RCTs) enrolling critically ill patients with low cardiac output syndrome (LCOS) admitted at pediatrics emergency and intensive care units ,Cairo University Children's Hospital, identified by treating medical team as requiring initiation of inotropic therapy based on healthcare team assessment of :

  • Capillary refill time > 3 sec
  • Hypotension (less than the 5th percentile or less than 90/50 mmHg for children 10 years or older (Kleinman et al.,2010) (Haque et al .,2007)
  • Oliguria (urine output that is less than 1 mL/kg/h in infants, less than 0.5 mL/kg/h in children ) (Nakano et al.,2022)
  • Metabolic acidosis with base excess > -2 (Nakano et al.,2020)

Patient randomization will be done by a computer based generation , serial enveloped numbers will be taken for the patients. Cardiac assessment will be done by a blinded pediatric cardiologist. If at any time the randomly assigned therapy considered to be failed or unsafe to continue, the treating physician will discontinue randomization and will continue with the appropriate medication according to the patients need.

Every patient will be evaluated after the first 24 hours of starting the inotropic therapy by :

  • pre and post inotropic therapy ICON measurements ( evaluating cardiac index and systemic vascular resistance pre and post inotropic support)
  • pre and post inotropic therapy echocardiography ( evaluating systolic and diastolic dysfunction by M-mode and two dimensional methods) through measuring LV EDD cm, LV ESD cm, LV EDV ml, LVESV ml, FS% , LV mass, EF% , MAPSE cm, TAPSE cm.
  • pre and post inotropic therapy clinical assessment of vital signs (heart rate , blood pressure, capillary refill time and urine output as mention before)
  • The need of titration up of inotropes :

Milrinone will start by 0.25 , 0.5 , 0.75 we can titrate up with time interval 3 hours after re-assessment.

Dobutamine will start by 5, 10 , 15, 20 we can titrate with time interval 15 mins after re-assesment.

-Time to achievement of therapeutic endpoints for hemodynamics

  • adequate blood pressure
  • clinically adequate cardiac output ( capillary refill time < 2sec , urine output that is more than 1 mL/kg/h in infants, more than 0.5 mL/kg/h in children, full conscious )

Data will be collected for each patient in form of [ Time Frame: Through first 24 hours up to first week since admission ] :

  1. Total time on inotropes (in hours)
  2. Non-invasive or invasive mechanical ventilation Total number of days requiring non-invasive or invasive mechanical ventilation
  3. Change in cardiac index ([CI] measured with ICON
  4. Change in systemic vascular resistance [SVR] measured with ICON
  5. Presence of acute kidney injury (defined as an increase in serum creatinine or a decrease in urine output or both over hours to days.) (Jacob J et al.,2020)
  6. Absence of metabolic acidosis (BE -2 to 2)
  7. Arrhythmia requiring medical team intervention, either through electrical or chemical cardioversion or any intravenous anti-arrhythmia medication administration
  8. Need for up-titration or addition of new vasopressor therapy
Being tested
Dobutamine

What participants receive

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

  • DobutamineDrug

    Also called milrinone

    Patient randomization will be done by a computer based generation , serial enveloped numbers will be taken for the patients. Cardiac assessment will be done by a blinded pediatric cardiologist. If at any time the randomly assigned therapy considered to be failed or unsafe to continue, the treating physician will discontinue randomization and will continue with the appropriate medication according to the patients need.

    Milrinone will start by 0.25 , 0.5 , 0.75 we can titrate up with time interval 3 hours after re-assessment.

    Dobutamine will start by 5, 10 , 15, 20 we can titrate with time interval 15 mins after re-assesment.

What is being measured

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

  1. time to achievemnets of theraputeic endpoints of hemodynamics

    ( normal blood pressure and clinically adequate cardiac output)

    Measured: first 24 hrs

Secondary outcomes (4)
  1. Correlation between the used inotropic support and the survival to discharge .

    Measured: first week

  2. Total time on inotropes and average length of stay at a pediatric intensive care unit.

    Measured: first week
