70 ANIMAL CASTRATION 



the omeiiTimi with tlie ema.sriilator, after which return that portion which 

 remains in the inguinal canal back through the internal abdominal ring into 

 the abdominal cavity. If there is evidence of the internal abdominal ring 

 being abnormally enlarged it is safest, in fact advisable, to gather up the 

 tunica vaginalis and ligate it as near the internal abdominal ring as possible 

 with chromicized catgut (14 day) large size. Proceed the same as for in- 

 guinal and scrotal hernia, page 46. If thought advisable tluTc is na 

 special oljjection to jjacking tlie scrotum with sterile gauze and suturing. 

 Remove the sutures and packing in twentj'-four to thirt,y hours and irrigate 

 the canal and scrotum once dail.v for eight days witli Lysol or cresol com- 

 pound (U. S. P.), one tablespoonful to eacli quart of water. Daily exer- 

 cise at pasture or walking exercise is advisable. 



PR(IL.\PSE OF INTESTINE 



This is another rare tliougli dangerous and annoying sequel of castration, 

 which is always fatal unless treated promptly and properly. 



Operative Techiiic — Same as outlined above for treatment of prolapse of 

 the omentum, with the exception that if the loop of intestine is distended 

 Ijy gas, tile gas slKndd be released by using the small trocar and eanula. If 

 the internal abdominal ring is contracted or too small to permit the return 

 of the intestinal loop, it becomes necessary to enlarge the ring (kelotomy) 

 l)y using a probe jioint bistoury. 



IN.JURIES AS RESULT OF CASTING 



It is ]5ossil)le f(U' tlie animal to receive lialter burns, lacerations and abra- 

 sions of various kinds. Rupture of tlie muscles and tendons sometimes oc- 

 curs. The vertelirac and other lioiies may become fractured. Home horses 

 present radial paralysis as a sequel of casting, while others be. ome ex- 

 hausted and never rise after being released. The correct treatment of these 

 conditions must be left to the judgment of the operator. Thcj' are men- 

 tioned more as a warning to him to exercise care, good judgment, and dis- 

 cretion in manipulating his restraint teclmic than for any other reason. 

 "Safety first" should be the motto. 



COLIC 



Post-operative colic characterized by abdominal and scrotal pain, and 

 not infre(iuently by more or less flatulence, is by no means a rare occur- 

 rence, especially in old stallions and cryptorchids. 



Treatment — Choral hydrate or fluid extract Cannabis Indica in one ounce 

 doses at two-hour intervals until the pain subsides. 



Peritonitis 

 Septic infection is the direct cause of peritonitis as a sequela of castra- 

 tion. The infection ma.y be introduced at the time of operation by contami-
