34
what suture material is commonly used for cat spays?
Ligatures: Synthetic absorbable multifilament or monofilament, Catgut sometimes used Muscle: Synthetic absorbable short-duration monofilament, e.g. Monocryl Subcutaneous layer: Synthetic absorbable short-duration monofilament, e.g. Monocryl Skin (commonly using an intradermal suture pattern): Synthetic absorbable short- duration monofilament, e.g. Monocryl
35
what are the possible complications due to spay surgery?
Haemorrhage Ovarian remnant syndrome (bit of ovary left behind) Stump granuloma/pyometra (rare) Urinary tract injury (trauma to the ureter during resection of the uterus) Abdominal hernia Wound infection
36
what are the key areas of post op monitoring following a spay?
Standard GA monitoring and post GA care Signs of internal haemorrhage – dropping BP, pale mms, lethargy Problems with wound – oozing, swelling, discomfort Ensure no patient interference with wound
37
what are the main areas involved in spay post op care?
``` pain relief stop patient interference with wound rest feeding post op checks ```
38
what pain relief is usually given to spay patients?
opioid and NSAID common on day of op | often sent home on oral NSAIDs
39
how can patient interference with wound be prevented?
buster collar body suit supervised time with it off only
40
how long should patients be kept rested for following spay?
10 days short lead walks avoid jumping etc
41
how should the spay patient be fed post op?
bland diet immediately post GA back to normal food after warn owners of need to reduce calorie intake in long term
42
when are post op checks for spay's needed?
2-3 days and then 10 days post op | check recovery from GA and wound healing
43
what are the main techniques for castration?
surgical (orchiectomy) | medial (chemical castration)
44
what is scrotal ablation?
removal of testis and scrotum usually performed if there is a problem with the scrotum itself
45
what extension of the peritoneum covers the testis?
vaginal tunic
46
what is open castration?
vaginal tunic is incised
47
what is closed castration?
vaginal tunic left intact
48
how is the epididymis attached to the vaginal tunic?
via a ligament
49
what approach is used for dog castration?
pre-scrotal midlien
50
where is the dog positioned for castration?
dorsal recumbency | surgeon may stand on either side
51
what must be checked before GA for neutering?
presence of both testis | that the animal is definitely female (cats)
52
where should the clip for dog castration be placed?
Clip area between tip of penis and scrotum and several centimetres on either side
53
why should you take care when clipping a dog for castration?
avoid clipping too close on the scrotum itself – the skin in this whole area is very sensitive, beware clipper rash!
54
what is sometimes placed in castrations during prep?
LA in testicles / incision site
55
what instruments are needed for dog castration?
Standard soft tissue kit – at least 3 artery forceps
56
what are the common suture choices for dog castrates?
Ligatures: Synthetic absorbable multifilament or monofilament, e.g. Vicryl or PDS. Catgut may still be used Subcutaneous layer: Synthetic absorbable short-duration monofilament, e.g. Monocryl Skin (commonly using an intradermal suture pattern): Synthetic absorbable short-duration monofilament, e.g. Monocryl
57
what approach is used for cat castration?
scrotal - an incision on each testicle
58
what position should cats be in for castration?
lateral recumbancy
59
where should be clipped for cat castration?
Clip just the scrotum and immediate surrounding area
60
are drapes usually used for cat castration?
no
61
what instruments are needed for cat castration?
Common to only use a scalpel blade and no kit | Some surgeons prefer to use a pair of artery forceps
62
when do testicles normally descend?
30-40 days
63
what is advised if testis have not descended by 6 months?
surgical removal
64

the both testicles even if one not retained
66
where can retained testicles be found?
anywhere along normal path of descent
67
what are the main classifications of location of retained testicles?
pre-scrotal inguinal abdominal
68
how should the patient be prepped for an inguinal or pre-scrotal castration?
similar to routine castration but with wider clip
69
what is needed to remove a retained testicle if it is abdominal?
exploratory laparotomy
70
what are the possible complications due to castration?
Scrotal bruising/swelling Haemorrhage - either Scrotal haematoma or haemoabdomen Infection Self-trauma – very common without a buster collar
71
what are the key areas for peri-operative monitoring of castration patients?
Standard GA monitoring and post GA care Signs of haemorrhage – internal (dropping BP, pale mms, lethargy) or external (swelling/bruising of scrotum) Problems with wound – oozing, swelling, discomfort Ensure no patient interference with wound
72
what causes most of the complications in castration patients?
patient interferance
73
what pain relief is given following castration?
opioid and NSAID injections on the day dogs sent home with oral NSAIDs cats often fine with just injections
74
how is patient interference with castration site prevented in dogs?
buster collar | suit can be used but dog may lick outside or still be able to reach incision
75
how is patient interference with castration site prevented in cats?
not often prevented as cats don't tend to lick and it is of benefit for them to keep their bottom clean
76
how long should dogs be rested for following castration?
10 days - short lead walks, no jumping
77
how long should cats be rested for following castration?
~2 days
78
when are castration post op checks needed for dogs?
2-3 days and then 10 days post op
79
when are castration post op checks needed for cats?
may have on at 2-3 days but don't usually need more | some practices don't do any
