In the treatment of hypoxic episodes in children with Tetralogy of Fallot, mild cases can be alleviated by positioning the child in a knee-chest position, while severe cases should receive immediate oxygen therapy, along with appropriate medication to correct acidosis. It is important to regularly eliminate factors that may trigger hypoxic episodes, such as anemia and infections, and to maintain a calm environment for the child. If these measures do not effectively control the episodes, emergency surgical repair should be considered.
