Welcome to the web pages for the Neuroanaesthesia SIG. The Neuroanaesthesia Special Interest Group exists to foster interest in matters relating to the perioperative care and anaesthesia of patients with intracranial and spinal pathology. This includes the application of basic and translational science relevant to clinical anaesthesia. Most of this activity revolves around the NeuroSIG sessions at the ANZCA annual scientific meetings and Australian Society of Anaesthetists/New Zealand Society of Anaesthetists meetings. There is a three-day biennial NeuroSIG meeting that alternates between venues in Australia and New Zealand.
