analgesic gases like nitrous oxide.7 Every year in the UK, 97,000 tonnes of CO2e(t/ CO2e) is released from volatile anaesthetic gases8
for ~450,000 surgical procedures.9 The
environmental impact is significant - one of the most common anaesthetic gases is desflurane and using just one bottle has the same global warming effect as burning 440 kg of coal.10 “As a Trust we’ve committed to being as green as possible,” explains Craig Murdock, Senior General Manager Clinical Engineer at Castle Hill Hospital in Cottingham. In 2023, NHS Humber Health Partnership opened the first phase of its £40m day surgery centre (DSC) to help reduce waiting times and address the surgical backlog resulting from the COVID-19 pandemic. The Centre includes pre-assessment facilities and 10 operating theatres for planned procedures, ranging from ear, nose and throat procedures to joint replacements and spinal surgeries. Mindray’s A9 anaesthesia workstation is among the cutting-edge equipment at the centre. “The A9’s AnaeSight feature will help us monitor
how much volatile agents are being used so we can accurately benchmark our environmental impact. Compatibility with SageTech’s gas scavenging system is a bonus too. We can capture exhaled waste volatile anaesthetic agents and reuse them before they are released into the atmosphere. Anything that can monitor and reduce our footprint is so useful.” Castle Hill’s DSC will also benefit from a range
of gas reduction tools on the A9 to efficiently manage leakages and gas delivery. Anaesthetic Gas Scavenging System (AGSS) terminals measure the flow of waste gas, and an e-AGSS system automatically turns the AGSS off during standby to prevent waste gases going to the atmosphere. Automatic Controlled Anaesthesia (ACA) also automatically adjusts the fresh gas and vaporiser output to quickly achieve preset target end-tidal agent and inspiratory oxygen concentration to avoid waste. “It’s been quite a transition to using a whole
new anaesthesia solution, and the Mindray team have been very responsive to our needs.” adds Craig. “Mindray proved to be the best and most cost-effective option during our procurement process, which was great as it also meant we could standardise equipment across the DSC, alongside the Mindray BeneVision monitors we already had in place. Efficiency and cost- effectiveness are key priorities for us with the DSC. The build is on phase 3 now and it truly is a state-of-the-art site with state-of-the-art equipment.”
Flexibility for the future As the population ages and patients become more medically complex, there are increasing
numbers of diagnostic and therapeutic procedures performed outside the main theatres environment. This poses several new challenges. Anaesthetists may be physically distant from patients or colleagues, the workspace may be small and unfamiliar, and there may be a lack of manpower. With this in mind, Mindray has released the A3 anaesthesia system. Its customisable gas supply options make it safer to work in unpredictable environments. To enhance patient safety further, high-flow nasal cannula oxygen (HFNC) can be delivered via integrated or standalone systems and gas flow can be precisely measured with the digital flowmeter. To improve efficiency, the A3 anaesthesia
system provides comprehensive connectivity and data management features for better visibility of patient statuses in each operating room and to streamline maintenance. For full flexibility, the A3 has four configurations to make the most of the space available, making it ideal for the induction room.
Stronger together So where does anaesthesia go next? David Britton, PMLS Marketing Manager for Mindray UK outlines the company’s approach, “It’s all about working with our customers. Understanding their initial pain points, where we can help, and what they see as the biggest challenges on
the horizon. Advanced tools, convergence of equipment and interoperability will be key, while presenting data in user friendly formats. “As a global business we invest 10% of our
turnover into R&D across all our product lines. That doesn’t happen in a bubble. We always encourage conversations and knowledge exchange between our customers and R&D team. For anaesthesia at the moment, there’s rightly a lot of focus on managing the sustainability of theatres. As more Trusts digitalise we’re actively collaborating with them to implement the right digital workflows so they can work efficiently, and ultimately, deliver excellent and safe patient care.” References available on request.
