Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* 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
