    The gi’eat objection bo the use of powerfully astrin- gent drugs (such as iron salts and silver nitrate) as local haemostatics is that they frequently cause in- flammation and sloughing of the tissues. Secondary haemorrhage sometimes occurs on the separation of the slough, though this is less likely to occur if the part be kept aseptic. Hence the use of such agents, except as a last resort, is to be avoided. In applying a styptic drug for the arrest of haemorrhage after tooth extraction, it is necessary first of all to remove clot and dibris from the socket, which can be effected by syringing or mopping. (When once the bleeding has ceased the clot must, of course, not be interfered with.) Then wipe the socket as dry as possible, so as to ascertain from which part the bleeding proceeds, and, in the case of multiple-rooted teeth, from the alveolus of which root; then quickly, before the blood collects again, apply the drug on a pledget of cotton-wool or lint, taking care that it comes in contact with the bleeding point. Leave the wool in place, and over this place pieces of rolled lint, so as, if possible, to obtain pressure from opposing teeth when the jaws are closed, or secure by ligature to neighbour- ing teeth. Bandaging the jaws together may bo necessary in the case of young patients. Instruct the patient to avoid lying down, or taking stimulants or warm food or drink. Internal hsemostatic medicines may be adminis- tered at the same time, though not much to be relied upon. Eemove the plug within twenty-four hours, or decomposition and consequent septic infection may result. Perri Perchloridum. perchloride of iron. Fcj Cfj. Materia Medica. Incompatibles.
