Check for inguinal hernia (or history of)
Size
Demeanour
Henderson Castration
Crushing forceps attached to closed vaginal tunic/cord
Forceps fits onto a drill
Haemostatsis is by crushing and elastic recoil of arterial wall
Donkeys do not require GA for castration
False they always do
Tool used in castration
emasculator
Common side effect of castration
Haemorrhage
Eventration
Oedema
Infection
Excessive Hemorrhage Treatment
Identify bleeding vessel
Must identify stump of cord and tunic
clamp/ligate artery (realistically you may need to re anesthetise the horse)
Beware of horses bleeding in to their abdomen
Evisceration of Small Intestine happens when?
Intestine enters inguinal canal, Intestine strangulates
Because you performed an open castration under general anesthesia
Because of the presence of an inguinal hernia
Excessive oedema from castration can be relieved by:
opening sealed wound and with scrotal massage or by inserting finger into scrotal cavity
rigorously exercising horse
vigorous hosing of scrotal wound
NSAIDs
Champignon
Persistent Strep. infection
Large red, granulation tissue within the open castration wound, often on the end of the cord
Treatment involves resection of the affected portion of the cord
Not common
Hydrocele (vaginocele)
Fluid build up within closed tunic post castration
Hydrocele (vaginocele)- Treatment
Drainage only temporarily alleviates the condition
No treatment is necessary if hydrocele does not inconvenience horse
Champignon- Treatment
Treatment involves resection of the affected portion of the cord
Scirrohous cord
Infection with Staph aureus
Microabscesses
Caused by contaminated emasculator or ligature
Open method of castration may predispose
Scirrohous cord-Treatment
May resolves with antimicrobial therapy & re-establishment of drainage
Removal of infected stump may be required, esp if cord was ligated
