Study reveals sustainable possibilities for veterinary anaesthesia
An online version of the study is available at
A recent study highlights the potential for conservative low-flow anaesthetic techniques

A study published in the Journal of Small Animal Practice (JSAP) has found that low flow anaesthetic techniques could significantly reduce greenhouse gas emissions and financial expenditure in veterinary practices.

The study. “Sustainable veterinary anaesthesia: single centre audit of oxygen and inhaled anaesthetic consumption and comparisons to a hypothetical model”, considers the way in which anaesthesia delivered via a circle system, lowering fresh gas flows, can reduce the carbon footprint of veterinary practices. 

The study retrospectively reviewed records of one hundred consecutive anaesthetics from a typical week at the Queen Mother Hospital for Small Animals, RVC, UK. The study included cases in which the anaesthetic had an accompanying record of the animals' bodyweight and all the five minute recordings of fresh gas flows and vaporiser settings for the duration of the anaesthetic. 

The anaesthetics in the study were reassessed to establish whether reductions could be made by utilising a conservative low-flow technique, and desflurane was swapped for an equipotent dose of sevoflurane when there was not a clear benefit to its use. 

Study author, Matt McMillan, said: “All inhaled anaesthetic agents are greenhouse gases and by reducing the fresh gas flows we use as much as possible, through the utilisation of rebreathing systems, we can reduce the amount of them released into the atmosphere. Ultra-low flow anaesthesia may not be achievable in many situations but this study demonstrates that, by adopting a simple conservative-low flow anaesthetic technique, practices which routinely use non-rebreathing systems should be able to significantly reduce the carbon footprint of anaesthesia.”

Commenting on the importance of the work, McMillan said: “We often don’t think of the environmental impact of veterinary practice, but it can be extremely wasteful. Just like in every other aspect of modern life, we have a duty to reduce emissions of greenhouse gases to help slow climate change.”

The editor of JSAP, Nicola Di Girolamo, commented: “As veterinary professionals, we recognise the importance of protecting the environment and doing what we can to reduce our carbon footprint. This study was a good first step towards understanding the potential reductions in IAA consumption that can be made in veterinary practice.”

VetCT app offered to students and new graduates

News Story 1
 The VetCT app is being offered for free to students and new veterinary graduates for their first three months in practice. The app provides a service for vets to send case information to a global team of Diploma-holding specialists, who can provide advice and support via instant call-back, text chat, written report, or virtual appointment.

Time on the app is automatically logged as CPD with quarterly certificates being generated for users. Additional services include the ability to book bespoke CPD, significant event reviews, and live training sessions such as surgical procedures.

The app is downloadable for both iOS and Android systems.

HORIBA to host CPD webinar

HORIBA has announced that it will host an online CPD meeting focusing on 'Exotic Parasites - The Importance of Testing in The Imported Dog'. Ian Wright (BVMS, MSc, MRCVS), head of ESCCAP UK and Ireland, will present on the importance of testing protocols in diseases of imported dogs.

The meeting will provide attendees with an overview of emerging veterinary diseases with a particular focus on exotic parasites, and discuss the importance of accurate testing protocols and equipment, alongside a final Q&A session.

The webinar will take place on Thursday July 1, from 19.30pm to 21.00pm BST. For free registration and more information visit the Horiba website or
