HEMS Debrief – Cardiac Arrest Focus. #11, Dr Úna Nic Ionmhain

Welcome back to the Sydney HEMS debrief. We are up to episode 11! Today, we are pivoting towards toxicology. Specifically, we discuss some of the more common toxidromes encountered pre-hospitally, how they cause cardiac arrest, and what providers – in particular pre-hospital providers – may do in order to best resuscitate these patients. In addition to some broader and very applicable learning themes pertinent to any toxidrome, we discuss Beta-blockers Calcium channel blockers Amitriptyline Quetiapine …and more Of course we are not doing discussing this alone. We are so luck to be joined today by a clinical toxicologist, Dr Úna. Dr Úna Nic Ionmhain graduated from Trinity College Dublin, and subsequently trained in Emergency Medicine in Perth. She completed a Pre Hospital and Retrieval Medicine year with CareFlight NSW as well as a poisons fellowship. She is now a staff specialist FACEM at Liverpool Hospital NSW, and a clinical toxicologist with the NSW Poisons Information Centre. She has an academic interest in HIET in toxicology for cardiogenic shock, which was the focus of her masters thesis, and is a passionate educator with a particular interest in cardiotoxicity. We sure hope you enjoy this episode, and until next time, we hope you have a great week.
