WOUNDS AXn Til KIR TREATMENT. 493 



to lOG' F., the appetite is lost, thirst is present, the horse reeks with 

 sweat, and his anxious countenance shows the pain he suffers. Tie 

 may lie clown, thou*;!! mostly he persists in standing, and the oppo- 

 site limb becomes greatly swollen from bearing the entire weight 

 and strain for so long a time. The wound, which at first appeared so 

 insignificant, is now constantly discharging a thin, whitish or yel- 

 lowish fluid — joint oil or water, which becomes coagulated about the 

 mouth of the wound and adheres to the part in clots like jelly, or 

 lesembling somewhat the white of an egg. Not infrequently the 

 joint opens at diHerent places, discharging at first a thin, bloody fiuid 

 tluit soon assumes the character above described. 



Trcatmeni of these wounds is most diilicult and unsatisfactory. 

 We can do inuch to prevent this array of symptoms if the case is 

 seen early — within the first 24 or 48 houi-s after the injury; but 

 when inflammation of the joint is once fairly established the case 

 becomes one of gi'ave tendencies. Whenever a punctured wound of 

 a joint IS noticed, even though apparently of but small moment, we 

 should apply without the least delay a strong cantharides blister over 

 the entire joint, being even careful to fill the orifice of the wound 

 with the blistering ointment. This treatment is almost always effec- 

 tual. It operates to perform a ciu'e in two ways — first, the swelling 

 of the skin and tissues underneath it completely closes the wound 

 and prevents the ingress of air; second, by the superficial inflamma- 

 tion established it acts to check and abate all deep-seated inflamma- 

 tion. In the great majority of instances, if pursued soon after the 

 accident, this treatment performs a cure in about one week; but 

 should the changes described as occurring later in the joint have 

 already taken place, we must then treat by cooling lotions and the 

 application to the wound of chlorid of zinc, 10 grains to the ounce 

 of water, or a paste made of flour and alum. A bandage is to hold 

 these applications in })la(e. which is only to be removed when swell- 

 ing of the leg or increasing febrile symptoms demand it. In the 

 treatment of open joints our chief aim must be to close the orifice as 

 soon as possible. For this reason repeate«l probing or even injec- 

 tions are contraindicate<l. The only probing of an open joint that 

 is t() be sanctioned is on oin' first, visit, when we should carefully 

 examine the wound for foreign brulies or dirt, and aft<n' removing 

 them the probe must not again be used. The medicines used to 

 coagulate the synovial dischai'ge are be>;t simply applied to the sur- 

 face of the wound, on pledgets of tow, and held in place by band- 

 ages. Internal treatment is also indicated in those cast»s of open 

 jf)ints in which the sulTeiing is great. At first we shoidd administer 

 a light physic and follow this up with se(latives and anodynes, as 

 directed for contused wounds. Later, however, we should give qui- 

 nin or salicylic a<id in l-draui doses two or three times a day.
