278 DISEASES OF THE DOMESTIC ANIMALS 



the wound is to be sealed with iodoform and collodion (1-8), and 

 iodoform gauze or gauze saturated with the corrosive solution ban- 

 daged over the puncture ; whenever this is possible, Bier's treatment 

 is in order. Immobilization of the joint is also desirable. 

 For this purpose slings, for horses, and a covering of plaster of 

 Paris or adhesive plaster and splints may be used. Sometimes 

 blistering with mercury biniodide (1-8) of the neighboring parts 

 is practiced, and when a bandage can not be used this may properly 

 be done. In dogs, plaster of Paris, with a window for inspection 

 of the wound, is indicated. 



Large penetrating wounds of the joint should be irrigated for 

 half an hour or so with lysol (2 per cent.) or corrosive (1-3,000) 

 solution and closed by suture, when the wound is fresh and there 

 is any probability of an aseptic result. Even with fracture of the 

 bones entering into the joint, a favorable recovery sometimes fol- 

 lows this method, providing the joint is thoroughly covered with 

 gauze saturated with corrosive sublimate solution and immobilized 

 as just advised for punctures. If infection occurs the wound must 

 be reopened and drained. With infection of the large joints in the 

 large animals — especially if there is fracture associated — the out- 

 look is unfavorable and at best anchylosis is to be hoped for. In 

 dogs, where the limb can with ease be completely immobilized in 

 plaster of Paris and a window left for treatment, the prognosis is 

 much better. Thorough drainage and frequent antiseptic irrigation 

 of the joint are then required for joint infection.

Bier's Hyperemia Treatment. 



In human surgery no new method of treatment has proved so 

 valuable as this within the last decade in which it has been used. 

 Bier's treatment depends upon hyperemia produced artificially. 

 Active hyperemia is brought about by heat, as hot air, etc. Passive
