If the object which produced the puncture is still lodged in the tissues, it must, as a matter of course, be withdrawn. After which, the further measures to be adopted may be enumerated under the following heads: careful regulation of the manner of living; removal from the system of all material which--attracted to the wounded part by the pain--might there cause irritation or inflammation; and protection of the body against any harm that might come to it through the occurrence of convulsions. These three measures are indicated for all wounds of nerves. But, in the case of a punctured wound, still other procedures should be employed, as will be discussed under a fourth head. The four heads mentioned by Guy may be briefly stated in the following terms: I. The patient should be put upon a light and very simple diet; and, in addition, he should be given a bed that is soft and humid (“_humidus et mollis_”). His surroundings should be kept quiet, and nothing should be permitted to disturb his peace of mind. II. To protect his tissues from the injurious influence of any superfluous matters of an irritating nature that may be circulating in the blood (_i.e._, cacochyme), a vein on the opposite side of the body should be opened and a certain amount of this fluid withdrawn. In certain cases, furthermore, it may be well, in addition, to administer an aperient remedy. III. If convulsions develop, the head, neck and the entire back should be anointed with well-warmed linseed oil or common (? olive) oil, as recommended by Galen. IV. Special measures should be adopted for providing a free outlet for any pus that may form in the deeper parts of the wound; and here again Galen recommends for this purpose the employment of one of several medicinal preparations which he enumerates. “But the more certain course,” Guy adds, “is to make an opening in the skin either with the razor or with the actual cautery (which latter, according to Henri de Mondeville, is the better plan of the two), and then to apply some subtle drying remedy which possesses the power to penetrate into the deepest recesses of the injured nerve--for example, savin oil.” (Guy has a good deal more to say on the subject of wounds of nerves, but the few extracts given above should suffice.) It is now a well-known fact that Guy de Chauliac was in the habit of treating fractures of the thigh by the employment of the weight and pulley as means of keeping up a continuing extension of the damaged limb. As his description of the method in question is very brief, it may not seem out of place to reproduce it here. Translated into English it reads as follows:--
