When infants have irritable stomachs, gastric catarrh, or when they persistently refuse food or are too feeble and marasmic to take sufficient food, they are fed by the method of "gavage," which consists in pouring liquid nourishment into the stomach through a glass funnel attached to a catheter. A soft-rubber catheter (No. 7) may be used. The child is wrapped in a sheet to restrain the arms, and then laid on its back upon a table. The catheter is passed through the mouth for a distance of about 8 inches, and warm milk or broth and, if necessary, medicines may be poured in.
