52. When the sufferer is brought to the surgeon at the end of half an hour, having lost a limb below the thigh or shoulder by a cannon-shot, he will often be found in a state of such great depression as to be likely to be destroyed by the infliction of a serious and painful operation like amputation, unless chloroform should relieve it. This has occurred to me so often as to induce me formerly to recommend delay for four, six, or even eight hours, if the unfortunate person did not suffer much, and appeared likely to be revived by the proper use of stimulants. If he should be in great pain, the limb should be removed under chloroform.
53. This recommendation originated from the fact that, as one seriously wounded man has as much claim as another to the attention of the surgeon, all could not be attended to at the same time; and the success following the deferred cases of amputation was as great, if not greater, than in those on which the operation was more immediately performed.
54. The advantageous results of _primary_ amputations, or those done within the first twenty-four, or at most forty-eight hours, over _secondary_ amputations, or those done at the end of several days, or of three or four weeks, have been so firmly and fully established as no longer to admit of dispute.
55. When an amputation is deferred to the secondary period, a joint is often lost. A leg which might have been cut off below the knee in the first instance is frequently obliged to be removed above the knee when done in the second.
56. In the secondary period after great injuries, the areolar and muscular textures near the part injured are often unhealthy, the bones are in many instances inflamed internally, and their periosteal membranes deposit on the surrounding parts so much new ossific matter as frequently to envelop in a few days the ligatures on the vessels, and render them immovable, necrosis of the extremity of the bone following as a necessary consequence, thus protracting the cure for months.
57. Sloughing of the stump, accompanied by inflammation of the vein or veins leading to the cava, frequently takes place. This state of stump is often followed by purulent deposits in and upon the different viscera, and principally in the cavities of the chest. Where febrile diseases are endemic, they often prevail; the constitutional irritation is great; the stumps do not unite, or, if apparently united, open out and slough, and frequently after a few days implicate the veins.
