PAYOH VETS
1. INJECTABLE ANAESTHESIA from a practice in Malacca.
According to the vet who runs a practice in Malacca, the UPM professors had been using the following formula safely and effectively for the past 15 years in dogs and cats. He had been using it for the past 10 years.
1.1
Zoletil 100 (don't use the diluent provided).
Add in the bottle 8 ml of ketamine
Add in the bottle 2 ml of xylazine
Dose: 0.04ml/kg IM. 0.03ml/kg very slow IV.
Use isoflurane gas if needed or top up 1/2 to 1/3 dose IM when the dog wakes up.
1.2
Zoletil 50 (don't use the diluent provided).
Add in the bottle 4 ml of ketamine
Add in the bottle 1 ml of xylazine
Dose: 0.04ml/kg IM. 0.03ml/kg very slow IV.
Use isoflurane gas if needed or top up 1/2 to 1/3 dose IM when the dog wakes up.
|
1.3
For CATS Be careful. Use the IV dosage for IM injection. That is 0.093 ml/kg for IM. Top up if necessary. |
Zoletil is an expensive drug and therefore the above combinations is less expensive and effective and safer.
|
2.
Dr Kieren Maddern's tips Ketamine & ACP - excellent for cats. Ketamine alone makes the cat's body rigid. Seldom use atropine (makes throat dry). 3. A Singapore's vet's tips Xylazine + Atropine + Ketamine. Then use isoflurane gas. Once he used nitrous oxide, the dog died. |
Each vet has is own method. Therefore vets stick to what has been successful in the past.

Injectable Anaesthetics For Cats
e.g. animal shelter work in the field and cost considerations. Zoletil, Domitor and isoflurane are costly.
CATS
1. XYLAZINE + ZOLETIL ANAESTHESIA
5 kg
Xylazine 0.1 ml + Zoletil 100 0.1 ml in one syringe IM
If insufficient, top up with Zoletil 0.01 ml IV to effect.
|
In one case of a 5kg male cat, I topped up with Zoletil 100 at 0.05 ml + 0.1 ml saline IV after 10 minutes of the xylazine 0.1 ml + Zoletil 0.1 ml IM combination. Effective analgesia for neuter. |
2. XYLAZINE + KETAMINE
3-4 kg
Xylazine 0.1 ml + Ketamine 0.4 ml in one
syringe IM. If insufficient, top up with
Zoletil 0.01 ml IV to effect.
For cats 4-6 kg, double the above dosage
IM.
|
I
use this xylazine:ketamine
combination formula frequently for
spay and neuter of cats without
problems. Duration of anaesthesia is
half an hour. I find that xylazine
0.15 ml + ketamine 0.6 ml in one
syringe IM is sufficient for cats
around 4 kg. The cat sleeps over
half an hour. If IV is needed, consider the cat's femoral vein if the cephalic vein is too small. |
3.
DOMITOR + XYLAZINE
Domitor 0.1 ml + Xylazine 0.1 ml in one
syringe IM.
If insufficient, top up with Zoletil 0.01
ml IV to effect. Domitor is expensive for
stray cat spays.
I have not used this before.
4. IF USED ALONE, adverse effects are
as follows:
1. Insufficient analgesia. Needs to top up
IV.
2. Salivation and legs rigid (ketamine IM)
3. Wakes up fast
Combined with xylazine will make the cat
sleep longer.
There are many combinations in practice
and each vet has his own favourite
combination used safely and with great
efficacy.
