So this time we're going to be talking about subarachnoid haemorrhage. So this is going to be a short and punchy look at a really important and interesting topic in subarachnoid haemorrhage. We run through the approach to headache and then focus on the specific features and findings that we should be looking for with regards subarachnoid haemorrhage. We then consider who we should be investigating further, what value a CT head brings and the sticky subject of who should be going on to have a lumbar puncture. Finally we consider the the management once the diagnosis of SAH is reached and how we can ensure the best outcomes for our patients. At the time of recording NICE has published its draft version of Subarachnoid Haemorrhage Caused by a Ruptured Aneurysm; diagnosis and management, which will be a great resource once finalised. Once again we’d love to hear any thoughts or feedback either on the website or via twitter @TheResusRoom. Enjoy! Simon, Rob & James
