and you have had no problems using lignocaine with cats (is lidocaine different to lignocaine?? ). As I mentioned one lecturer said it is contraindicated in cats as may cause bradycardia - I meant to ask the lecturer after the talk but forgot.

Have to say have never had any apnoea problems with our bags, whether it is the rate or amount that is different to the people who have known problems, never been commented to any of us that there may be problems and Dan Lewis who drew up the recipe we use would most defiantly have said if there was, and have never used any loading bolus.

We tend to use an infusion pump but can run on own on big dogs if need be.

Do not use patches for the reason Nick said and also no real idea of how long they last it varys and how much yes l know a patch but it is to vague/animal.

Fentanyl patches: have used them can take up to 24hrs to take effect, therefore pain relief must be provided up until this point, plus if using warming devices, such as bair huggers, patches must be removed as the heat will cause increased blood supply to the skin, therefore speeding up drug in take and possibilites of overdosing. althou patches are good for post op pain relief as they last up to 72hrs.

we use a few combinations for anagesia. the most common being ketamine & morphine and ketamine alone. If you use ketamine as a CRI you ahve to give a loading bollus to ensure serum levels are high enough prior to starting infussion. We also use fentanyl as an infussion drug using a syringe driver. Just as a word of warning if using fentanyl or ketamine as CRI under anaesthesia they can cause apnoea, so get ready to start IPPV or have the ventilator handy. haven't got any doses to hand, but will check them out at work tomorrow and get back to you. We generally dilute the drugs in 100ml bags of saline to prevent wastage

dont have personal experience of the bags - but have heard of them. Have you considered fentanyl patches at all for cats?

If you check out the Wiki on here l put up the formula for analgesia bags some time ago from 100ml to 1ltr saline bags, flow rate additives etc. It is under the Fluid section under Clinical documents.

Use them a lot and they make a big difference as get some pretty horrendous injuries come through emergency clinic.
