Stimuli, however, should always be used with much caution and prudence, and never unless fully warranted by the train of symptoms under which the patient is labouring at the time; when the circulation is restored in the limbs, and is becoming throughout steady and more natural, all sources of excitement must be abandoned and carefully avoided, as there is considerable risk of reaction proceeding to too great a height. The patient is to be kept quiet in a darkened room, cold applications made to the head, previously shaved, and free motion of the bowels procured by neutral salts with antimony, or by other purgatives not of an irritating nature, and not given in such doses as to prove violently cathartic. Enemata are in some cases preferable, and are always a valuable adjunct, to the employment of purgatives by the mouth; they procure evacuation from the larger intestines, in which feculent matter chiefly accumulates; they ought to contain asafœtida and turpentine; with these additions more salutary effects are produced than from mere evacuants. The latter ingredient would seem, by its local stimulus, to impart energy to the bowels sufficient for the correct performances of their functions, while the former tends to allay spasm and irritation, both locally and generally. If the circulation becomes unduly excited, abstraction of blood from the system, in sufficient quantities and at proper intervals, is absolutely necessary; and the depletion must be regulated by the symptoms and circumstances of each case. The action will in general be more speedily and effectually moderated by one copious bleeding at the commencement, than by repeated bleedings to a less extent. An easy and open state of the bowels is of much importance in the excited stage. Mercurial preparations are sometimes useful, as they are known to possess the power of causing the absorption of coagulated lymph and serum, and probably of preventing their effusion. In cases where insensibility continues after the arterial excitement has been subdued, counter-irritation on the head or the back of the neck is often useful, as the application of blisters, or the rubbing in of antimonial ointment. These are supposed to act by causing an unusual influx of blood to the surface, producing a change in that fluid by the copious purulent, serous, and lymphatic secretions from the irritated part, and thereby diminishing the distended and engorged state of the internal vessels, which might produce considerable compression of the brain.
