Brief Summary

A condition of decreased serum T3 level in children after cardiac surgery using cardiopulmonary bypass has been commonly recognized as euthyroid sick syndrome (ESS). This syndrome has been closely associated with low cardiac output syndrome after heart surgery. The unique characteristics of pediatric patients with congenital heart disease (CHD) in Indonesia have caused ESS to arise in the population even before surgical managements. Thyroid hormones increase cardiac function, respiration and diuresis. Increased myocardial function occurred through the improvement of mitochondrial effectiveness as the body energy source by utilizing effective energy substrates, lactate and pyruvate. Prevention of decreased serum thyroid hormones level by T3 supplementation could be clinically beneficial. Intravenous T3 unit dose is very expensive and inapplicable for daily use. In adult studies, oral T3 was found to be effective for the prevention of decreased serum T3 levels; similar study on pediatric population, however, has not been elucidated.

Outcome Measures

Primary Outcomes (1)

  • Intubation time

    All patients after undergoing congenital heart surgery will be supported by mechanical ventilation. Duration of this support since cross clamp off removal until after surgery will be assessed in the treatment and placebo group. Thyroid supplementation will increase the cardiac function and will make the patients extubated early than the patients without supplementation

    Until patients extubated after surgery in ICU OR died OR still intubated within 7 days

Secondary Outcomes (2)

  • Number of patients with low cardiac output syndrome

    6 hours, 12 hours, 18 hours, 24 hours, 48 hours post aortic cross clamp removal

  • Drug adverse reaction

    Every hourly until 12 hours post cross clamp removal, every 3 hours until 24 hours, every 6 hours until 48 hours, every 12 hours until 72 hours post cross clamp removal, and until the patients discharge from hospital

Other Outcomes (9)

  • Inotropic and vasoactive-inotropic score

    1, 6, 12, 18, 24, 36, 48, 60 and 72 hours post cross clamp removal

  • Diuresis

    From day 1 until day 3 post surgery

  • Fluid balance

    From day 1until day 3 post surgery

  • +6 more other outcomes

Study Arms (2)

Oral triiodothyronine

EXPERIMENTAL

Oral T3 (triiodothyronine) is given 1 mcg/kg every 6 hourly through naso-gastric tube since induction of anaesthesia for 60 hours

Drug: Oral triiodothyronine

Placebo

PLACEBO COMPARATOR

Placebo (saccharin lactic) is given every 6 hourly through naso-gastric tube since induction of anaesthesia for 60 hours

Drug: Placebo

Interventions

Oral triiodothyronine is given peri-operatively through naso-gastric tube

Also known as: Tetronine, Lyothyronine
Oral triiodothyronine

Placebo consist of saccharin lactis that has the same appearance as Tetronine

Also known as: Saccharin lactis
