From bruised and lacerated wounds there is little or no hemorrhage, but in proportion to the severity of the bruise, is the bleeding slight, and the danger great. The bloodvessels are so torn and twisted as to permit the spontaneous and temporary suppression of hemorrhage to occur almost immediately; and the larger arteries may escape entirely, owing to their elasticity. Sometimes after bruised wounds, such as those inflicted by gunshot, the large vessels bleed instantly and violently; often, however, hemorrhage occurs only after the sloughs separate, many days after the infliction of the injury, and then it is generally very profuse; in some instances, limbs are torn, bruised, or shot away, without hemorrhage occurring to any great degree, or at any period. Frequently the vitality of the parts surrounding the wound is much diminished; and the whole limb is apt to become gangrenous, either immediately, on account of the extreme violence of the injury, or consecutively, from greatly excited action going on in parts whose power of resistance has been much impaired: it often arises also from constitutional peculiarity. The gangrene extends often rapidly, in consequence of the infiltration of putrid serosity into the cellular tissue. In the treatment of bruised wounds, the position of the parts must be carefully attended to; they must be placed in a state of relaxation. In general, it is unnecessary to retain the margins of the wound in contact, for adhesion cannot occur—suppuration must ensue, and is to be desired—and the dead and dying parts must be loosened and discharged before union can take place. Sometimes, as when a large flap has been detached, and the parts not much injured otherwise, approximation ought to be accomplished, for the reasons already mentioned. In almost all cases, and most certainly in those in which the mechanical injury has been severe, and its effects extensive, violent inflammatory action is to be dreaded, and measures must be taken to ward it off: notwithstanding the prophylactic treatment, violent inflammation often comes on, and then recourse must be had to the means proper for the subduing of it. Blood is to be taken from the part, if necessary, and soothing applications used, in the form of fomentation and poultice. The main indications are to prevent extravasation into the substance of the limb, and strongly excited action. When the sloughs begin to separate, emollient poultices promote the suppuration and discharge of dead matter, and afterwards the sore must be dressed, according to the nature of the case, with the applications most fit for granulating sores in their different degrees of action and advancement. During the after treatment, the sides of the sore ought to be well supported, so as to prevent, as much as possible, suppuration from extending along the neighbouring cellular tissue; but, at the same time, the dressing must not be so tightly applied as to cause irritation.
