why and why not

unwanted seasons ( rubbing on owner )



population control ( has a greater effect than castration )



pyometra



why not- increased risk of cruciate damage

when

anoestrous or late metoestrous ( after oestrous ) if in oestrous then wait 3 months.



no evidence to say that it is better or worse for urinary incontinence if done before or after 1st season. It is easier to do prior to 1st season ( as early as 6 months ) because the is less development of musscle

approach location for new graduate

2cm Cd to umbilicus to near pubic rim ( 8cm)

bitch technique ( main variations )

both start the same, get uterus ( horn usually ) by sliding fingers down the body wall/ break the ovarian ligament ( aka suspensory ligament ) - attached to body wall near last rib - using dry swab or cut !/ create window in broad lig- suspends tract from body wall - /place clamps on - 2 proximal to ovary and 1 distal and remember to not place the clamps over each other/A- cut prior to putting ligatures on or B- put ligatures through window then cut/ tear broad ligament to reflect uterus cd/ put ligatures in crushed area/ hold stumps for 30 sec bac inside cavity then release if not bleeding/put two clamps on Cr vagina and ligate making sure your clamps are close.

ligature material ( no. 1 choice and reasons )

PDS gives the best ligatures as it does not loosen.



vicryl tends to slip.


cat gut tends to break.

pyometra spay technique

ligate uterine arteries separately then put your 2 clamps on the Cr Vagina as normal and ligate

closure technique

linea alba - simple interupted



subcut- simple continuous



skin - simple interupted ( can do intradermal but means that owner might let do exercise too soon as the linea alba takes 3 months to regain 75 % of its strength )

cat flank spay ( landmarks, incision, tips )

landmarks - last rib/lumbar muscle and greater trochanter.



incision - 2cm below lumbar muscle 2-3 cm long. 2 muscle layers.



tips - make sure the peritoneum is included in the muscle layer or else it will be hard to cut/ should be beneath sublumbar fat/ use a single ligation/ if in season dont clamp horns just broad lig.

rabbit spay problems

GI is just waiting for your blade/ large amount of fat around ovary / ovary and oviduct are quite far apart/ all very friable/ should use a ligature which encircles everything as any individual blood vessels in the broad ligament must be ligated
