Study summary

This is a study to determine the safety and efficacy of liothyronine sodium/triiodothyronine (Triostat), a synthetic thyroid hormone, when given to infants with congenital heart disease during cardiopulmonary bypass surgery.

Read the detailed description

Patients will be randomized to receive study drug or placebo and randomization will occur stratified to each diagnostic category. All patients undergo preoperative echocardiograms to provide preoperative cardiac function data. The study drug or placebo will be provided in the operating room as an iv bolus just prior to cardiopulmonary bypass and as a bolus delivered on release of the aortic cross-clamp. This will be followed by iv for 12 hours. Operative data will be collected including CPB time, aortic cross-clamp time, length and degree of hypothermia. These data will be extracted from the anesthesia record.

Study arms

  • Active comparator
    Liothyronine Sodium/Triiodothyronine

    bolus administration of Liothyronine Sodium/Triiodothyronine (Triostat) immediately prior to CPB institution and after removal of aortic cross clamp, followed by repeated boluses, will be safe and will result in significant improvements in postoperative and clinical outcome parameters and cardiac contractile function.

    Drug: Liothyronine sodium/triiodothyronine · Procedure: Cardiopulmonary bypass and cardiac surgery

  • Placebo comparator
    Placebo

    bolus administration of Placebo immediately prior to CPB institution and after removal of aortic cross clamp, followed by repeated boluses

    Drug: Liothyronine sodium/triiodothyronine · Procedure: Cardiopulmonary bypass and cardiac surgery

What researchers measure

Primary outcomes

  1. duration of mechanical ventilation after cardiopulmonary bypass.

    Reducing the length of ventilatory support minimizes other postoperative complications, which can contribute to morbidity.

    Time frame: 0 to 72 hours

Secondary outcomes

  1. Assess other parameters

    * Need for mechanic circulatory support, fluid balance (intake and output); urine output * Echocardiographic measures to include end-systolic wall stress/fractional shortening ratio * Myocardial performance index (Doppler derived), cardiac index (Doppler derived) * Heart rate, blood pressure and central venous pressure * Free and total T3 levels * Others: All medications including inotropic agents will be recorded with respect to time initiated, terminated, and dosage will be recorded for exploratory analyses.

    Time frame: 0 to 72 hrs
