547. How long does it take to spay a female dog at Toa Payoh Vets? 26 minutes
KEY PERFORMANCE INDICATORS FOR SPAYING A HEALTHY
FEMALE DOG AT TOA PAYOH VETS

How long does it take to spay a female dog without complications? A case is illustrated.
The answer is around 26 minutes from skin incision to the end of stitching.
The whole process from sedation to the end of stitching is 31 minutes.

A case spayed by me as an example:

Fox Terrier, Female, 1 year, 9.3 kg
Last heat 3.5 months ago. Skin incision 1.5 - 2.0 cm long. Spay hook is used. No subcuticular or subcutaneous sutures as they do irritate the dog. No IV drip set up.

1. Time when the dog is given Domitor + Ketamine IV*. Atropine IM (A).
2. Wait 5 minutes. Isoflurane + oxygen gas in mask. Intubate.
3. Time when the skin is incised (B).
4. Time when the skin is stitched (C).

The following key performance indicators are as follows:
C - A should be less than 35 minutes
C - B should be less than 30 minutes




No. of suture packets used - one packet 2/0 absorbable
No. of stitches to close the linea alba - 3 simple interrupted
No. of stitches to close the skin - 2 horizontal mattress
Skin incision 1.5 - 2.0 cm
DOMITOR + KETAMINE IV WITHOUT NEEDING ISOFLURANE + O2 IN HEALTHY YOUNG DOGS
At 10kg bodyweight, Domitor = 0.4 ml. Ketamine = 0.5 ml. Total = 0.9 ml in one syringe. Give via IV.

If the above is given at 50% of the calculated dosage, isoflurane + O2 top up for less than 60 seconds, to effect (eyeball rolls ventrally and other signs) will be needed. Intubation is needed. Atropine IM is advised before surgery. Antisedan IM after surgery may be useful to get the dog to wake up within 2 minutes.
