This paper reviews the history of IBA, cites case examples and reports a survey of emergency responder experience. Methods Literature and narrative review and focused survey of pre-hospital physicians.

It is characterised by the cessation of spontaneous breathing following a TBI and is commonly accompanied by a catecholamine surge witnessed as hypertension followed by cardiovascular collapse. This contradicts the belief that isolated traumatic brain injury cannot be the cause of shock, raising the possibility that brain injury may be misin...
