Brief Summary:
Infants and children undergoing cardiac surgery require mechanical support for circulation called cardiopulmonary bypass. The artificial pump ensures that blood flow to the body is maintained during surgical procedure on the heart. However, the pump circulation disrupts regulation of thyroid hormone. This hormone is a critical regulator of heart and circulatory function. Deficiencies in thyroid hormone adversely affect recovery of the heart after cardiac surgery. A recent study by the principal investigator showed that supplementing patients younger than 5 months old shortened the time spent on the ventilator (breathing machine) after surgery. Populations undergoing heart surgery in developing countries such as Indonesia are different than those in the U.S. and other industrial nations. For many heart defects children undergo surgery at an older age. They are then sicker for longer periods, and are often malnourished. These older malnourished children have lower thyroid hormone levels even prior to surgery, and show dramatic further drops after surgery. Shortening time on the ventilator should improve their recovery, and also improve overall availability of resources in developing countries. The formulation of thyroid hormone provided in the U.S and given intravenous is relatively expensive. However, a much more inexpensive formulation is available in Indonesia, which can be given through a tube extending from the nose to the stomach. We propose testing this formulation made in Korea, known as Tetronine, in two vulnerable populations in Indonesia: children younger than 5 months of age, and those older than 5 months who are malnourished. All these patients will be undergoing cardiopulmonary bypass for congenital heart defects. This project will be an important collaboration between U.S and Indonesian investigators. If successful, it will have a general positive impact on care of the entire population of young children undergoing cardiac surgery in developing countries by reducing time on the ventilator and improving access to care.

Arm Intervention/treatment
Experimental: Tetronine
Oral T3 (Tetronine) is given 1 mcg/kg every 6 hourly through naso-gastric tube since induction of anesthesia for 60 hours
Drug: Tetronine
Oral T3 was given 1 microgram/kgBW q6h since induction of anesthesia for 11 doses (for 60 hours)
Other Name: Oral Triidothyronine (T3)

Placebo Comparator: Placebo
Placebo (saccharin lactic) is given every 6 hourly through naso-gastric tube since induction of anesthesia for 60 hours
Drug: Placebo
Placebo was sacharum lactis, given q6h since induction of anesthesia for 11 doses (for 60 hours)
Other Name: Saccharin Lactic

Primary Outcome Measures :
  1. Intubation time [ Time Frame: Up to 7 days post surgery ]
    All patients after undergoing congenital heart surgery will be supported by mechanical ventilation. Duration of this support on mechanical ventilation after surgery will be assessed in the treatment group and placebo group. Thyroid supplementation will increase the cardiac function and will make the patients extubated early than the patients without supplementation.

Secondary Outcome Measures :
  1. Inotropic score and vasoactive-inotropic score [ Time Frame: 1, 6, 12, 18, 24, 36, 48, 60 and 72 hours post Cross clamp removal ]
    The amount of inotropic drugs are calculated and reviewed serially since cross clamp removal until all drugs are stopped.

Other Outcome Measures:
  1. Fluid balance [ Time Frame: Until day 3 ]
    Fluid balances include amount of diuresis, chest drain production, peritoneal dialysis, and the use of diuretics.

  2. Hemodynamic parameter [ Time Frame: Every hourly until 12 hours post Cross clamp removal, every 3 hours until 24 hours, every 6 hours until 48 hours and every 12 hours until 72 hours post cross clamp removal, ]
    Hemodynamic parameter such blood pressure, heart rate, heart rhythm, and body temperature

  3. Low cardiac output syndrome [ Time Frame: 6 hours, 12 hours, 18 hours, 24 hours and 48 hours post aortic cross clamp removal ]
    Low cardiac output in which clinical sign and symptoms of low cardiac output are found with or without the increasing of arterial and venous saturation gap and metabolic acidosis and the condition needs 100% inotropic support or even more than that from the beginning of inotropic used, the use of new inotropic, mechanical support, or other maneuvers in order to increase cardiac output (e.g pacemaker)

  4. Ejection fraction [ Time Frame: Day 1, 2 and 3 after surgery ]
    Ejection fraction is measured by Echocardiography

  5. Cardiac output [ Time Frame: Day 1, 2 and 3 post surgery ]
    Cardiac output is measured by echocardiography

  6. Systemic vascular resistance index (SVRI) [ Time Frame: Day 1, 2 and 3 after surgery ]
    SVRI is measured by echocardiography
