Difficult to get accurate drug calculations
Hypoglycaemia - don’t starve too long
Where does the ovarian blood supply sit
Caudal pole of each kidney
Common concerns/issues of ovariohysterectomy
Patient positioning
Finding the uterus
Breaking suspensory ligament
Safe ligation of ovarian pedicle
Safe ligation of uterus/cervix
Indications for flank ovariohysterectomy
Enlarged mammary gland
Pregnancy
Pyometra
Oestrus
Obesity
Under 12 weeks old
Disadvantages for flank
ovariohysterectomy limited exposure to contralateral side
Difficult to identify previous OHE
Imperfections in hair colour
Best knot for ovarian pedicles
Modified Millars
Most common complication of ovariohysterectomy
Haemorrhage
Dealing with haemorrhage in ovariohysterectomy
Increase exposure
Use suction
Convert to midline
Get assistance
Retract bladder caudally
Sinus/discharging tracts post ovariohysterectomy
Soft painful swelling with or without discharge
Can be caused by FB reaction
Issues of residual ovarian tissue
Continued cyclicity
Right more common than left as more difficult to expose
Can be easier to find remnant in oestrus
Always open ovarian bursal to ensure whole ovary removed
Suture pattern for uterus
Double layer continuous
Appositional inner - simple continuous
inverting outer - Cushing, lembert, Utrecht
Closure of uterus
3/0 or 4/0 monofilament absorbable suture with taper point or taper cut needle
Uterine stump granuloma
Signs consistent with infection
Vaginal discharge
Attractive to males
Neutrophilia with left shift
Surgical intervention required
Most cases need broad spectrum antibiotics
