COMPLICATIONS AND THEIR TREATMENT. Though the operation of castration is comparatively simple in its various methods and is generally successful in its results, still it is not entirely free from accidents or complications. Indeed, among those likely to meet our notice, there are some of quite a serious character, which will develop themselves independently of the skill and care with which the operation may have been performed or whatsoever attention may have been bestowed upon the patient. Among these may be enumerated _colics_, _hemorrhage_, _swelling_ of the scrotum, _gangrene_, _abscesses_, _champignon_, _fistula_, _hernia_, _peritonitis_, _tetanus_, and _amaurosis_. COLICS. This, we have already seen, usually appears a short time after the completion of the operation, the suffering animal becoming uneasy, restless in his stall, pawing the ground with his fore feet, and sometimes lying down and rolling. As I have before stated, these symptoms, as a rule, are of short duration, and subside without other treatment than a little walking exercise. It is rarely the case that they fail to yield to an anodyne, or a dose of chloral may be demanded before the symptoms are subdued. TEARING OF THE CLAMPS. When this accident occurs it is commonly attributable to the omission of a careless operator to secure the tail of the animal in such a manner as to prevent its interference with those implements by its entanglement, and tearing them from the end of the cord, as a consequence. The result of this is the appearance of a hemorrhage from the spermatic artery, which can only be controlled by either a reapplication of the clamps to the end of the cord--if it can be thus secured--or by other means, which will be considered when we reach the subject of bleeding in general as connected with other causes. HEMORRHAGE May be primary or secondary. In the first instance it occurs in consequence of the insufficiency of the means of hemostasis applied to the end of the cord, as in the case of the operation by simple excision, by cauterization, the too rapid crushing of the cord, torsion, or the accident before referred to--when the clamps have been torn off and the cord lacerated about the point of their application.
