Veterinary Anursethesia

The circle breathing system that uses a carbon dioxide absorber should have a Fresh Gas Flow (FGF) that replaces oxygen which was ACTUALLY used for cellular metabolism.
The oxygen requirement for dogs and cats under general anaesthesia is 2-7ml/kg/min, but by using a calculation of 10ml/kg/min, we ensure patient safety.
A higher FGF is used initially to saturate the system with 100% oxygen and volatile agent, and also to push all the room air out the scavenge (room air is fu...ll of nitrogen = denitrogenise).
Then the FGF can be reduced to replace the amount of oxygen used in cellular metabolism. The unused gas from the anatomical dead space, which doesn't undergo gas exchange, and all the gas that are present in the hoses etc can be used again and not pushed out the scavenge.
NB: some vapourisers require a minimum of 0.5L/min for accurate delivery of a volatile agent. And thanks to Emma for the reminder that if using sidestream capnography this can take up to 250ml/min for analysis! This needs to be considered. Want to keep it easy for everyone to understand? Use a FGF of 1L/min.

Treat an intubated cats trachea SO gently! Disconnect the breathing system when turning the patients position during anaesthesia. Also - don't over inflate the cuff and always listen for a leak before inflating!
This kitty was "..diagnosed as having severe subcutaneous emphysema, most likely from a tracheal wall compromise that would have occurred as an adverse event from tracheal intubation".

New Anaesthesia guidelines for cats! Get your nerd on, it’s a big read! 😍

Exciteeeeement - no more throwing the bottle out on the day!
And if it is news to you, the original Alfaxan does actually need to be thrown out at the end of the day :) But not anymore!

An ECG pad/clip doesn’t always have to be stuck to, or clipped onto to the paw pads. The probe can be placed anywhere that makes reasonable contact!
This is one of my favourites - the inside of the ear.
This patient was having a bilateral foreleg procedure, so the ECGs were attached on the Left Hind, Right Hind and Left Ear. Which is where they would normally go, but upside down instead - the ECG trace appears normal too, just also upside down!

If you love anaesthesia and you’re not a member of the AVA, considering joining! Look at these meatier than the average webinars they put on.

Teach, mentor, support, guide, influence, inspire.
It’s so rewarding - share your knowledge and enthusiasm! I am so proud to be involved in the next generation of veterinary professionals going into the industry and (hopefully) enjoying anaesthesia that little bit more :)

Think quick - a 'blocked bladder' cat is on its way to your practice. Sedation and/or anaesthesia will need to be provided. Are you familiar with the special anaesthesia considerations?

Fancy a quick early morning refresh on capnography traces? Enjoy! ☕️ ☀️ 🤓

Invasive arterial blood pressure (IBP) vs non invasive arterial blood pressure (NIBP) monitoring with both Doppler and Oscillometric machines: invasive monitoring usually the most reliable!
But why the difference here on the on the same patient but different techniques? The NIBP cuff is placed on a leg that is hanging off the table, and the patient is in sternal recumbency = the cuff is well below the level of the heart. This can lead to an overestimation of the blood pressure by around 7mmHg per 10cms of height difference. If the cuff is placed higher than the heart it will underestimate by around 7mmHg per 10cms of height.

This #refreshingmonday is a nice one - a bite sized picture of oxygen going into the blood for cellular metabolism, and the carbon dioxide waste product on its way out to be expired!

A #pharmacyfriday fun read on adrenergic receptors! The what now? The ones where the epinephrine (Adrenaline) works ;) Its a short but meaty refresh!

Intratesticular Local Block:
A pretty straightforward video for a straightforward procedure! Tag your vets, and together - jab those testicles #locoforlocal
This #watchitwednesday is a nice short video, and ends with the person performing the local block patting the testicles 🤭 job done!

This #popuptip gives you a couple of ideas on where you can place ECG probes or clips when you may not have access to all the limbs. Place two of them on either the hind or foreleg paw pads, and place the 3rd one by the ear, under the tongue or even up the nose. ​

VA Case: What’s going on here? . This patient is a #brachycephalic dog, in #anaesthesia recovery and has just been #extubated after a soft palate resection and the nares widened. In the series of photographs, can you see what is happening? . This patient is unable to maintain normal #oxygen saturation on room air post-anaesthesia.... . Under anaesthesia, the Fraction of Inspired Oxygen (#FiO2) provided by an oxygen source is close to 100%, versus 21% in room air. Some patients need support through the transition back to room air. . Anaesthesia drugs that are still on board during recovery can depress the #respiratory centre as well as an anatomy related obstruction, potentially leading to #hypoxaemia. . Do you monitor oxygen saturation in the immediate post-operative period? This can be done while the patient is still #intubated but all anaesthesia gases have been disconnected, or in recovery for brachycephalic breeds as they often have their tongue hanging from their mouths! . Providing flow by oxygen can raise the FiO2 to 40% depending on the method used. This was done for this patient who went on to make a full recovery.

This video highlights the trouble that brachycephalic breeds have due to their excess soft tissue. Not only in everyday life, but also anaesthesia!
Look after that airway!

your posts are so helpful xx
