Oxygen – too much of a good thing? | ESAIC 2023
Our coverage of Euroanesthesia 2023 continues; The European Society of Anaesthesiology and Intensive Care (ESAIC) is the leading European Organisation for Anaesthesia, Intensive Care, Pain and Perioperative Medicine. TopMedTalk is proud to bring you ‘as live’ coverage of their annual conference. For more information on the work ESIAC do check out their website here https://euroanaesthesia.org/ This piece is a discussion about oxygen; can you have too much of a good thing? Join Desiree Chappell, Monty Mythen and Andy Cumpstey, NIHR Clinical Lecturer in Anaesthetics & Intensive Care Medicine, Southampton. We mention this paper here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9438193/ And we discuss www.exovent.org
Perioperative oxygenation | EBPOM London 2020
“Oxygen is the commonest drug that we give to our patients today during surgery and the general anaesthetic” but what do we really know and understand about it from a perioperative perspective? This talk illustrates why, even with some of the evidence and background physiology that we have at our fingertips today, the following questions are still perplexing: How much is too little oxygen? How much is too much oxygen? And how much is just the right amount of oxygen? Presented by Daniel Martin, OBE, Professor of Perioperative and Intensive Care Medicine, University of Plymouth and the Royal Free Hospital, London.

COVID 19 | Oxygen economy, CPAP and ventilators
Our guest is an intensivist and specialist in dangerous transmissible diseases as well as being one of the scientists who took part in the Xtreme Everest expedition which investigated the effects of human tolerance of hypoxia. What about continuous positive airway pressure (CPAP)? Information suggests this may be more useful as we head into the pandemic stage “based on the experience the Italians are describing to us”. This piece looks at how the UK is preparing to tackle the global pandemic before asking some important questions about oxygen supplies. There’s a tendency for people to use more rather than less, should we look to reverse this? “We give people a range to put their oxygen saturation between and people naturally want to go for the higher end of that target,” in this time of crisis and potential shortages is it important to change that habit? “The whole National Health Service has changed its thinking…” the piece wraps with some thoughts about how enticing it is to see the UK’s Government and health service move to stop medics being bound by red tape and overly strict guidelines. Presented by Monty Mythen with his guest Dan Martin, OBE, Anaesthetist and Intensivist at the Royal Free Hospital and Reader at University College London (UCL).

Near infrared spectroscopy (NIRS) Round Table | EBPOM Chicago
Near infrared spectroscopy (NIRS) … ‘a variation of pulse oximetry; it transmits red and infrared light into tissue’ measures information from arterial venous and capillary blood simultaneously to deduce tissue saturation; an aggregate estimate of arteriovenous capillary blood and whatever tissue you’re shining the light into. ‘So typically, we’re using it in on the brain at least in the cardiac and vascular space, but people also in other areas like the surgical ICU, can use it to measure muscle oxygenation as well’. Learn how this technique could enhance your practice, what its potential for advancement is and where its limits lie. This piece is likely to be of critical interest to most cardiac surgeons and those who work alongside them. This piece was generously supported and brought to you by Medtronic. Presented by Desiree Chappell and Monty Mythen with their guests Robert Thiele, Cardiac Anesthesiologist and Intensivist at the University of Virginia, Carol Ann Rosenberg Associate Director of Perfusion and ECMO, Kenan Yount, Cardiac Surgeon and Director of the Valve center and Director of the Aortic Center at the University of Virginia.
Ernest Henry Starling Plenary Lecture, David Story | EBPOM 2021
One of the standout moments of Evidence Based Perioperative Medicine (EBPOM) 2021 this piece is a bonus podcast for the holiday season which looks in detail at oxygen from a perioperative medicine perspective, amongst other things this talk throws up some troubling and challenging observations about pulse oximetry. The piece is introduced by Mike Grocott, Professor of Anaesthesia and critical care at the University of Southampton. Presented by David Story, Professor and Foundation Chair of Anaesthesia at the University of Melbourne; Head of the University Department of Critical Care and a member of Council of the Australian and New Zealand College of Anesthetists (ANZCA) and the Chair of the ANZCA Safety and Quality Committee.

Finding Goldilocks, more or less | EBPOM 2020
With questions from the online audience, this piece looks at the “not too much and not too litte” sweet spot regarding fuel, fluid and oxygen; where is it and how do we get there, according to our distinguished panel? This podcast works well as a companion piece to the following talks which have already been released here on TopMedTalk: Helen McKenna, “Fuel, can you have too much?” https://www.topmedtalk.com/ebpom-2020-london-fuel-can-you-have-too-much/ Tim Miller “Optimising fluid and hemodynamic management during major surgery” https://www.topmedtalk.com/ebpom-london-2020-optimizing-fluid-and-hemodynamic-management-during-major-surgery/ Dan Martin “Perioperative Oxygenation” https://www.topmedtalk.com/ebpom-london-2020-perioperative-oxygenation/ Presented by Mike Grocott and Dennie Levett with their panelists; Tim Miller, Associate Professor of Anesthesiology from Duke University Medical Centre, Helen McKenna, is in the final year of her PhD at University College London, investigating bioenergetic and redox function in critically ill patients and Dan Martin, OBE anaesthetist and intensivist at the Royal Free Hospital and Reader at University College London (UCL).
Fuel: can you have too much? | EBPOM 2020 London
“As Anaesthetists the ultimate goal of almost all of our interventions and monitoring is to support cell energy production to provide mitochondria with the oxygen and the fuel they need to produce enough adenosine triphosphate (ATP) to power cell function and integrity”. How human cells produce energy, how this changes in response to stress and how this may influence survival; this piece focuses what we know about how our bodies get the fuel they need to survive surgery and thrive as a result, providing a positive long term outcome. This is not a piece about nutrition, it’s a provocative session exploring concepts designed to provide food for thought. Presented by Helen McKenna, is in the final year of her PhD at University College London, investigating bioenergetic and redox function in critically ill patients.
