Note 3 — PART FIRST. OF INFLAMMATION.
Reading edition
[Leeches may be applied to almost any region of the body, excepting such as are abundantly supplied with loose cellular substance, as the eyelids and scrotum; or traversed by large subcutaneous veins. Parts in a state of high inflammation must also be avoided, otherwise gangrene may be induced, an effect which I have several times witnessed in hospital practice: in a case of this kind they should be placed in the immediate vicinity of the disease.
Previously to applying them, the skin should be thoroughly cleansed with a wet sponge, and moistened with a few drops of milk, blood, or sweetened water. Dipping the leeches in table beer is very effective in rendering them lively and active. Having been withdrawn from the water in which they are kept for a quarter of an hour before, they should be held to the part by means of a glass tube, a roll of pasteboard, or a piece of linen. When there is plenty of space, as on the abdomen, chest, or back, and it is designed to use great number, they may be confined by an inverted tumbler or a wire-gauze cage. They should not, however, be crowded too closely together, as erysipelatous inflammation is apt to arise when this is done; and they ought not to be touched until they drop off of their own accord. If they remain on too long, their separation may be facilitated by sprinkling them with a little salt or vinegar: pulling them away is painful and liable to occasion irritable sores. The subsequent flow of blood, which is generally considerable, especially in children, is to be promoted by cloths wrung out of warm water, and reapplied every ten or fifteen minutes for several successive hours.
If the bleeding be profuse or continue longer than is desirable, it may be arrested by some styptic powder or lotion, either alone or assisted by a compress and roller. In obstinate cases, it may be necessary to apply the nitrate of silver or chloride of zinc; or, what is better, because more effective, to use the twisted suture made with a very fine needle and ligature passed through the sides of the little wound.—ED.]
