Diseases of domesticated birds (1920) Diseases of domesticated birds diseasesofdomest00ward Year: 1920 SURGICAL DISEASES 297 In some cases fluctuation occurs and in others the tumor remains hard. Surgical treatment involves incising the bottom of the swelling to allow the escape of the grayish semi-fluid contents. Sometimes the swelling contains a caseous mass of a lamellated structure. The cavity may be packed with gauze wet with perchloride of iron as a hemostatic and the whole foot bandaged. The bird is confined to an area not provided with a perch. The wound may be dressed every few days, some disinfectant being substituted for the per- chloride of iron. Likely the wound will continue to slough, and dis- charge an ill smelling secretion. In this event the foot may be bathed in a warm solution of compound solution of cresol. Iodine, zinc chlo- ride or lunar caustic may be applied to the interior of the wound. Often treatment may require months, and necessitate trouble out of proportion to the value of the bird. Bumblefoot has been attributed to injury resulting from jumping from high perches or to roosting on perches of an unsuitable, angular character. CUTANEOUS EMPHYSEMA Emphysema of the skin designates a condition in which there is an abnomial amount of air in the subcutaneous region. The cause is either a wound or spontaneous rupture of the or- gans containing air, such as the trachea, or the various air sacs and passages communicat- ing between them. The air imprisoned beneath the skin may so distend the skin that the bird appears almost like a ball. The condition occurs in young canary birds and has been reported in fowls, turkeys and pigeons. Radical correction of the trouble by preventing the leakage is not possible, but relief of the condition may be accomplished by slitting the skin to prevent accumulation of air. Fig. 56.
