Subarachnoid haemorrhage is one of the most time-critical and high-stakes emergencies in medicine. But in the real world, it rarely presents neatly. In this episode, Oli Flower is joined by two AI co-hosts — Simon (GPT-5.3) and Claude (Sonnet 4.6) — to work through the pre-hospital and emergency department management of SAH using a real-world scenario: a 42-year-old woman with a thunderclap headache, collapse, and reduced GCS. What follows is a mix of clinical reasoning, practical decision-making, and occasional AI overconfidence getting corrected in real time. What we cover: Airway decisions in SAH: Is GCS 8 an automatic intubation? Pre-hospital priorities and seizure management Blood pressure targets: physiology vs reality ED workflow: stabilise first or scan first? Hyperventilation and ICP: when it helps and when it harms Communicating with neurosurgery (and what actually matters) Nimodipine: what the evidence really says (and doesn't say) Why listen: This is not a guideline recitation. It's a practical, frontline discussion of how SAH actually presents and how decisions get made under pressure — including where the evidence is thin, debated, or misunderstood. Along the way: Dogma gets challenged Nuance matters And one AI model learns, the hard way, what happens when you misquote trials Key takeaways: SAH management is a balance between competing risks: perfusion vs rebleeding Early decisions in airway, blood pressure, and transport matter Much of what we do is still based on physiology and consensus, not definitive trials And yes — sometimes you're managing a brain with "buggered autoregulation" 🎧 If you work in emergency medicine, ICU, anaesthesia, or pre-hospital care, this episode will sharpen how you think about SAH from the moment the patient hits the floor to the CT scanner. 📍 ISAH 2026 — Sydney, 17–20 November Where these debates happen for real, with real humans.

This podcast episode features a conversation between Dr Oli Flower and his AI co-host, Simon (ChatGPT 4o), focusing on vasospasm and delayed cerebral ischemia (DCI) in aneurysmal subarachnoid haemorrhage (aSAH). The discussion covers: The distinction between radiological vasospasm (imaging finding) and DCI (clinical syndrome). The evolution of understanding DCI's multifactorial causes, beyond just vasospasm. Evidence and controversies around ICU management, including blood pressure targets, nimodipine use, and the role of other interventions. Screening and monitoring strategies: transcranial Doppler, CTA, CTP, and the limitations of each. Post-management assessment, therapeutic hypertension, and the emerging role of milrinone. The importance of multimodal monitoring and the future potential of AI and global data sharing. The episode closes with a lighthearted off-topic discussion about casting for the new Naked Gun movie. The conversation is rich in clinical nuance, highlights current evidence gaps, and emphasises the need for individualised patient care and ongoing research.

Catherine Bell takes us through how to troubleshoot problems commonly encountered when looking after patients who have an external ventricular drain (EVD) in situ. Issues with using brain tissue oxygen monitors are also discussed. A highly practical session aimed at bedside clinicians. This presentation was delivered by Catherine Bell at CODA2022.

Angiographic vasospasm and more accurately, delayed cerebral ischemia, continue to contribute to morbidity and mortality in patients with aneurysmal subarachnoid hemorrhage (SAH). It is known that angiographic vasospasm is common after SAH, occurring in two-thirds of patients. This presentation was delivered by Rob Loch MacDonald at CODA2022. Want more content about aSAH?

Lizzy suffered a substantial aneurysmal subarachnoid haemorrhage that left her critically unwell, requiring a long stay in intensive care recovering from the consequences and complications of this devastating form of stroke. Now a couple of years after her haemorrhage, Lizzy has come so far. She and her husband Gordon describe their experiences, right from the day it all began and through those tumultuous first few weeks, to where she is today. This open and honest account gives us all invaluable insight into what it's like to go through the subarachnoid haemorrhage journey from a patient and family's perspective, hopefully helping us empathise more and deliver better patient-centred care.

Andrew Udy talks about the ongoing BONANZA Trial which is assessing whether an algorithm that incorporates both ICP and brain tissue oxygen (PbTO2) can improve outcomes after traumatic brain injury (TBI). Like with all monitoring, how the PbTO2 is interpreted and managed is critical and the devil is in the detail!

Historically, when it came to brain injury, ketamine had a bad rap. Much of that dogma was dispelled in the last 20 years, and ketamine is now frequently used as an induction agent in acute brain injury, especially traumatic brain injury, partially due to the favorable effects on haemodynamics. However a new application of ketamine is now being explored - whether ketamine may be able to reduce secondary brain injury. In this talk Toby Jeffcote initially takes us through all the sedatives currently used in brain injury and the evidence to support their use. He then covers the history of ketamine use and the background to new research in use as a therapeutic agent. This podcast was recorded at the Brain Symposium which took place in March 2023.

Cortical spreading depolarization (CSD) is a spreading loss of ion homeostasis, altered vascular response, change in synaptic architecture, and subsequent depression in electrical activity following an inciting neurological injury.

Andrew Chow vs Andrew Udy This debate was set up to discuss the issues with categorising traumatic brain injury (TBI). The current system using GCS to divide patients into mild, moderate and severe has been criticised in recent times, with calls for a more nuanced approach. The debate was a just bit of fun but does highlight the key issues. Chowie didn't get to choose which side to argue for :) Andrew Chow, Intensivist with a neurosurgical background, argues that the current categorisation system for TBI works, and makes sense! He tackles us through the history of this system, and why it's important to differentiate different types of TBI. The arguments in favour of this categorisation include the consistency and benefits of a universal language, the implications for triage and management, and the fact that this system has been endorsed by all major organisations. Andrew Udy then argues that this classification is fundamentally flawed. He discusses the issues with the Glasgow Coma Scale, and therefore the follow-on issues in TBI classification, including all the confounders to the GCS, the issues with timing of the score as well as GCS not taking baseline function or specifics subtypes of TBI into account. He makes the argument that biomarkers may better categorise the diffuse entity we call TBI. This podcast was recorded at the Brain Symposium which took place in March 2023.
