I therefore switch off after the last skin suture (the skin is sensitive and painful)

I have been to lectures where veterinary anaesthatists will say you don't even need to flush patients with O2 and the diffusion hypoxia concern has been 'shunned' but I'd always give at least a good few breaths of 100% oxygen before moving to recovery.

great reply and totally agree

I had a crash section uga and when i came round i had not been given ANY pain relief, what so ever Hand on heart i can truthfully say all the hideous demonic pain i felt was in the skin, i was dopey obviously but can just recall the feeling of searing hot pain shooting across y abdo

I also went to a cpd thing with a lovely chap from the vds and he said that the second gas effect wasn't really an issue.

Nitrous has a similar effect to ketamine. It works on GABA receptors and stimulates the bodys own opioid system. It is the equivelant of giving a CRI of a pain killing drug during a GA.

It is therefore an awesome tool for analgesia during painful surgery, especially spays. Once turned off, it stops working, I notice many of my spays which I have managed to wean down to a very low % iso will become light quickly once it is turned off, meaning I have had to increase the % iso a little which is frustrating! I therefore switch off after the last skin suture (the skin is sensitive and painful) and provide 100% oxygen for a minute or 2 (while we tidy the wound, come off iso).

Cheers.

I tend to go 1:1 for dogs, never used it in cats.

When using it for a bitch spay, once the vet has the uterus & ovaries out and isn't doing anything too painful anymore, I like to start gradually decreasing my nitrous and increasing my O2 so that they have a smoother recovery.

Also, they need to have been on O2 ( +/- iso/sevo) for 10 minutes before you use nitrous, and make sure they get 10 mins O2 once the nitrous is turned off.

Hi Adam,

You can go for a 2:1 (66%nitrous to 33%oxygen) OR 1:1( 50%:50%), if your using a circle without ins/exp gas analysis go for 1:1 and leave the valve partially open if you using a non-rebreather gor for 2:1

if you've got insp gas analysis Keep the FiO2 above 33% :-)

Hope this helps
