_To stop a bleeding socket_ the alveolus must be well cleared of clots, and fragments of sponge, soaked in a solution of perchloride of iron, one part of the salt to three of water, packed into the cavity. A plug of cork is placed between the jaws, and a four-tailed bandage (see page 32) carried round the head to keep them firmly closed. Should this plan fail, the socket must be cleared again, and the wire of the galvanic cautery pushed well down to the bottom and then heated till it has cauterised the cavity (see page 168). =Nipple Shields and Artificial Nipples= made of flexible ivory, vulcanized india-rubber, &c., are required when the nipple is chafed and excoriated by the child’s sucking, especially if his mouth be attacked by thrush, as is usually the case. When the nipple is sore it should be well washed and dried after suckling, covered with glycerine of starch or plastic collodion and protected by a shield. If much inflamed it may be wrapped in lint dipped in alum water or solution of sulphate of zinc (one grain to the ounce), and deep chinks should be freely rubbed with lunar caustic. The breast should be regularly emptied by the breast-pump if the child’s sucking gives much pain, lest the accumulation of milk in the ducts cause milk abscess. =Plugging the Vagina= is employed in cases of rapid hæmorrhage from the womb, &c. _Apparatus._—1. A silk pocket-handkerchief. 2. A dry new fine sponge or pellets of cotton wool. 3. Silk thread. 4. A body roller or folded sheet. The sponge should be cut into pieces the size of nuts; if the sponge is compressed it answers better. When prepared, the vagina should be cleared of coagula by a syringeful of ice-cold water; the handkerchief, unfolded and thrown over the right hand, is passed up the vagina till its centre reaches the os uteri, the borders and ends then project from the vagina. The interior of the handkerchief is next filled by firmly packing the sponge in bit by bit until the vagina is distended by the mass; the ends of the handkerchief are then tied together. The sponge swells as it absorbs the blood, and compresses the bleeding vessels by its distention. The abdomen and uterus are then supported by a body roller, or folded sheet, wrapped tightly round the hips and waist, while the patient, lightly clad, is kept quiet in a cool chamber. When the plug has answered its purpose it is removed, by withdrawing the sponge bit by bit, and the vagina is washed with tepid water.
