Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Nitric Oxide

Active Comparator: Intervention arm - • Intervention arm will receive nitric oxide 20 parts per million (ppm) into the oxygenator of a cardio-pulmonary bypass circuit

No Intervention: Control arm - Control arm will not receive nitric oxide, they will receive standard bypass as per local policy


Treatment: Drugs: Nitric Oxide
Addition of nitric oxide 20ppm into bypass circuit

Summary
Brief summary
This trial will test if adding nitric oxide (NO) gas to the cardiopulmonary bypass (CPB)
circuit in infants undergoing an arterial switch operation (ASO) for Transposition of the
Great Arteries (TGA) changes the incidence of major postoperative adverse events (AEs).

Major postoperative AEs include cardiac arrest, emergency chest opening, use of ECMO (machine
that acts as an artificial heart and lung during surgery), and death.

Participants will be randomised to receive oxygen plus nitric oxide (intervention arm) or
oxygen without nitric oxide (control arm) during CPB.
