Glad to hear the anaesthetic went well.

Shame about the outcome

The anaesthetic went fine. After a sleepless night, pouring over my anaesthesia books and you lovely lot helping me!

Started off with a 4litre bag on a circle with a fully opened valve. Put him on 8litres of oxgen/min.

The bag seemed at full capacity so after a chat with the vet, we swapped him to a 6litre bag, which seemed to be a bit better.

Bad outcome however. He was PTS due to osteosarcoma.

Thank you all so much for helping me.

Haha you beat me to it nick - dont touch the valve - leave it open!Semi closed and closed system has nothing to do with the valve just reduce your FGF if its low flow anaesthesia your attempting after circuit has been primed with your initial flow rate- but if this is the case you should also be using capnograph like Nick said.Also agree no point in using HME as the circle already does this job for you.

Just for fun, it's his pelvis. DV!!!

So 8 litres to start then turn shut valve half way and reduce to what? 4litres?

You can go lower! but watch your inspired CO2 (not sure if you have capnograph or not....)

I always use the circle semi-open.

Thank you for being kind to me... he is lame on his left hind. We have a lateral and a DV of his left hind conscious but the vet would like a VD of the pelvis.

Bless him. He is 8 yrs old and a sweetie.

It is wonderful that everyone helps each other on this site. Thank you. x

which part of the dog is to be RADIOGRAPHED ()????

Can you try and elevate the patients chest a bit take some pressure off her diaphragm

Aww I wanted to say that but just SVN! Good to know that you ask the same NIck!

Is it a hip score? Or could you get away with rotating pooch a wee bit, as well as elevating them?

I would go for the circle too!

I'm sure Nick will be along soon, with more detailed advice

Here I am!!!!

I would echo what others have said and also pick a circle, plus use a 4litre reservoir bag. Once under GA resp rate might settle. Capnograph would be handy as low end title CO2 might be a prob due to tachypneoa (sp)

would start with a FGFR (frsh gas flow rate) of around 8litres/min and reduce it after around 15-20mins all things being well.

Can't think of anything else currently......

Good luck with it!

I also would use a circle, and if you have a heat and moisture exchange filter to attach between the et tube and circuit, I would use one of those as well. I believe your flow rate totally depends on what anaesthetic machine you have. Hope everything goes well

I personally would NOT use an HME. If using a circle frsh gas will be warmed once using low flow rates as it passes thru the soda lime, plus will add to mechanically dead space of the circuit which may cause probs with carbon dioxide levels

I would definately go with the circle, good luck!

I have gone for the circle circuit in this situation before

2nd vote for circle

I'm rubbish on Ga's but my choice would be a circle...
