One must always be alert to see the very first attempt at breathing, for unduly prolonged manipulations may defeat their own object; the natural inclination always is to do too much rather than not enough. In some instances, however, the measures thus far indicated will not prove successful, and, if not, the cord must be tied and cut through, for subsequent treatment cannot be conveniently carried out while the child remains attached to the placenta. As soon as the cord is severed the child is placed in a tub of warm water, about the normal temperature of the body, and is moved about in the bath for a few moments, the attendant watching closely all the while, for the breathing is often very superficial. Should signs of beginning respiration not appear, the attendant should grasp the child by the shoulders, dip it up to the neck in a basin of cold water and quickly return it to the warm tub. This operation may be repeated five or six times; generally the instant the child touches the cold water it draws up its feet, opens its eyes, and cries. One must take care that the plunge lasts but a moment; if the child becomes chilled efforts to revive it will likely be unsuccessful. Indeed, the necessity for keeping it warm must be constantly borne in mind. With the very exceptional cases in which hot and cold tubs are ineffective, the following method becomes valuable. Wrap the child in a blanket and lay it face downward upon a table or chair, allowing the head to hang over the edge. Roll the body on one side or a little beyond; then slowly roll it back upon its face and onward to the other side. This maneuver is repeated fourteen times to the minute, but not more frequently. When properly performed it secures a flow of air to and from the lungs with the same rapidity as in the normal respiration of an infant. Efforts to revive the child must not be quickly given up, as a successful outcome occasionally requires half an hour of work or even longer. One method after another should be tried in the order which I have indicated. A physician always perseveres so long as the heart-sounds can be heard; but, since an inexperienced person might be unable to decide upon this point, the most reliable course for the layman is to persist in the resuscitation until the physician arrives.
