GCS 8, thunderclap, seizing: the first hour of SAH, with two AI co-hosts

This one is an experiment. Oli Flower takes a real-world scenario, a 42-year-old woman with a thunderclap headache, collapse, seizure activity and a GCS of 8, and works through the pre-hospital and emergency department decisions with two AI co-hosts. They structure the problem well, surface the right questions, and at least once misrepresent the trial data with complete confidence until corrected. Which is rather the point.

The clinical content is the part that will not date: is GCS 8 an automatic intubation in a post-ictal patient who is improving, what does neurosurgery actually want to know on the phone, and how do you perfuse a brain with no autoregulation without blowing the aneurysm apart.

Worth listening for

• “Dead patients don’t scan.” Stabilise first or scan first, and what has to be true before you move.

• Hyperventilation as the reflex that is usually wrong.

• The blood pressure balancing act, and how little of it rests on trial data.

• Nimodipine: what it does, where the evidence came from, and the moment the AI gets it wrong.

Where this shows up in the program

The decisions in this episode are the ones argued on Wednesday in the Early Surgical Decision-Making breakout: Jordan Jones on treat tonight or wait until morning, Johnny Wong on whether the haematoma decides clip or coil in poor-grade SAH, Alex Adamides on when treatment is futile, and Jun Kim on EVD, lumbar drain or neither before the aneurysm is secured. John Laidlaw follows on Thursday morning with whether earlier securement always means better.

The nimodipine and blood pressure questions sit squarely in Thursday’s ASA × ISAH guidelines session, where the authors of the European and North American guidelines are put under the microscope together.

As for the co-hosts: Emanuela Keller opens Wednesday on precision medicine and augmented intelligence in acute aSAH, and Friday’s ISAH Futures panel takes on what AI will realistically change in aneurysm care over the next decade. With real humans, who can be corrected in person.
