Not that I'm aware of Bongo, but will cehck with our anaesthetist at work and get back to you next week. I always thought it was for denitrogenation due to high concerntrations within room air......

I know this is slightly off point but does anyone else find some staffies difficult to read under GA? This has happened to me a few times with different circuits/drugs etc.

Had one young staff the other day with brick red membranes, really slow resp rate, HR110-120, no pulse deficits, eye half way, according to sp02 he was fairly well oxygenated but I know these machines have their flaws! Pre med was pethidine and ACP.

Dog was having surgery to correct luxating patella. O2/N2O and just 1% isoflurane!! I ended up having a complete wibble and getting a vet to check it. She said she thought he was fine but said we would just have to leave him on 1% and watch him.

is that why we use higher flow rates to begin with when using a circle. I know its for denitrogenation but is it also for this?? I've had it before but am in two minds as to wheter the et tube had been tied too tied by another nurse??

if I am completely wrong with this please let me know cos I am a student!!

We only use oxygen and isoflurane.

Do you use circle systems???

Have been having a read and have found that 'Cherry Red' mucous membranes can be an indication of carbon monoxide present in the body

'The passage of some volatile anaesthestic agents over very dry CO2 absorbers (soda lime) results in accumulation of carbon monoxide within closed anathestic systms. Of the volatile agents desflurane produces the greatest amount, halothane produces the least (fang et al, 1995). this problem can be avoided by turning off the O2 flow of fail-safe macines when they are not in use to avoid the drying effects of continuous gas flow through the system'

The above was taken from the 10th edition of Veterinary Anaesthesia by Hall, Clarke & Trim.

Hi congested mucous membranes usually relate to toxic things like poisonings, pyos chf etc, but I have seen a few under ananesthesia, particularly border collies?? and the odd gsd I have seen it in, if they are not toxic looking they are usually so bloody pale you think they are gonna drop off the end of the et tube.

Ive normally only seem this to when the patient is toxic.

The other thing to check is that she isnt tying the wow bandage to tight and restricting the blood flow to the lips?? Have seen that happen with a trainee before!!
