Poisoned wounds are chiefly punctured. The danger of these wounds lies in the possibility that the poison is absorbed by the lymphatics and veins, and conveyed to the heart, whence the entire blood becomes infected. To prevent this a ligature should be tied above the wound, by means of a strip of muslin or preferably an elastic suspender, so as to check the free return of the blood by the veins and lymphatics. After which the poison should be sucked from the wound, or the wound should be cauterized, with carbolic or nitric acid by means of a sharp-pointed stick dipped into the acid and then applied to the wound, or _fired_ with a red-hot iron, crochet or knitting needle. The poison of snakes and tarantulas is neutralized with an alkali; the most efficient seems to be spirits of ammonia, but a strong solution of washing or even baking soda should be substituted when ammonia is not at hand. I would puncture and enlarge the wound of the sting with the point of a sharp knife or scissors, so that the alkali can come into immediate contact with the injected venom; the patient must be given frequent drinks of whisky, brandy or strong wine until a physician arrives to supervise further treatment. Wounds inflicted by poisonous insects like the bumblebee, honeybee, wasp, hornet, yellow jacket and mosquitoes produce wounds which are instantly followed by a sharp, pungent, itching pain, and in a few moments after by a pale, circumscribed, inflammatory swelling. Some persons have a peculiarity in their constitution that the poison of an insect gives rise to exceedingly alarming symptoms, such as palpitation, nausea, dizziness, dimness of sight and an indescribable sense of suffocation. The sting is sometimes left in the skin; for this the wound should be carefully examined, and when present drawn out. The most prompt and useful application is water of ammonia, or strong salt water, or strong soapsuds. Turpentine is also a valuable application. If the insect has lodged in the throat, large quantities of warm salt water and mustard must be immediately administered until the patient has vomited freely, and if there is a sense of suffocation leeches and afterwards hot poultices should be applied to the neck. If the system has become poisoned, and some of the distressing symptoms that were above enumerated are present, the internal use of whisky or brandy is called for. Hemorrhage is common to all wounds, and the loss of the blood depends upon the size and nature of the vessel that is injured. The bleeding that takes place in ordinary superficial wounds oozes from minute vessels, the capillaries, and slight pressure temporarily applied controls it. When an artery is wounded, the blood flows in intermittent jets, or in a running pulsating stream from the vessel. The venous blood is dark red and flows in a continuous stream and not under the same pressure as that coming from the arteries, hence it is much easier controlled.
