SURGICAL OPERATIONS.

Surgery is both a science and an art. The success of surgical operations depends on the judgment, skill, and dexterity, as well as upon the knowledge of the operator. The same fundamental principles underlie and govern animal and human surgery, although their applications have a wide range and are very different in many essential particulars. We must not lose sight of the fact that hygiene and sanitation are essential to the best results in veterinary as well as in human surgery.
Asepsis is an ideal condition which, although not always possible in animal surgery, is highly important in connection with the mechanical details of all surgical operations in proportion to the nature and seriousness of the same.
Aseptic surgery is considered to be the performance of operations with sterile instruments with the hands of the operator and the site of operation being rendered as nearly sterile as possible, and the wound treated during operation with sterile solutions and protected following the operation with sterile bandage material. In other words, it is the preservation of the highest degree of cleanliness in connection with operations.
Local or general anesthesia should be resorted to in painful and serious surgical operations, as operations upon all living creatures should be humanely performed and all unnecessary pain and suffering avoided. Anesthesia is necessary where absolute immobility of the patient is essential and where entire muscular relaxation is indispensable. The anesthetic condition is also favorable for the adjustment of displaced organs.
Large animals have to be cast and secured before an anesthetic is administered. For complete anesthesia inhalations of chloroform are generally employed; sometimes of both ether and chloroform. The quantity of chloroform required to produce insensibility to external impressions varies much in different cases and must be regulated, as well as the admixture of air, by a competent assistant.
If the probability of the success of an operation is remote and the animal is in healthy physical condition, so that its flesh is good for human food, it is more advisable to butcher the animal than to attempt a surgical operation that offers little encouragement to the owner. The best judgment has to be exercised in determining a matter of this kind, for no animal suffering from inflammation or that is in a feverish condition is fit for human food.
