The Glasgow Coma Scale (GCS) was first introduced in the 1970s to provide a simple and reliable method of recording and monitoring change in the level of consciousness of head injured patients. Since its introduction, the GCS has been widely utilized in the trauma community and its use expanded beyond the original intentions of the score. In the context of traumatic injury, this paper discusses the use of the GCS as a predictor of outcome, the limitations of the GCS, the reliability of the GCS and potential alternatives through a critical review of the literature. The relevance to Australian trauma populations is also addressed.

Eclampsia and severe pre-eclampsia are rare, but potentially life-threatening conditions that emergency physicians must be able to diagnose and treat promptly, because initial presentations to the ED are real possibilities. The treatment of the major complications of this disorder, hypertension and seizures, have been the focus of much research. Magnesium sulphate is now the first line agent for acute treatment and prophylaxis of seizures in eclampsia and pre-eclampsia. ⋯ Severe hypertension requires treatment with an intravenous antihypertensive agent familiar to the clinician. No single antihypertensive has been proven to be better than another, although in Australia, hydralazine is probably the initial intravenous agent of choice. Routine use of invasive haemodynamic monitoring and volume expansion is not recommended and consultation with obstetric colleagues is essential.

Ketamine has been known to the medical world for over 30 years, yet is not widely used to its full potential. It is often considered to be a 'third world' drug only. In light of a recent increase in interest in its use in the developed world, this review is for emergency physicians to use as a quick reference.

Blunt carotid artery injury is an uncommon injury with a potentially devastating outcome. Although treatment is often unhelpful for an established neurologic deficit, there is frequently a delay between the episode of trauma and the onset of neurology. This delay provides a window of opportunity where early detection and intervention may significantly improve outcome and prevent lifelong morbidity in a generally young trauma patient population. ⋯ Cerebral angiography revealed traumatic dissection of the left internal carotid artery with complete occlusion of the lumen just distal to its origin. After 13 days in the intensive care unit and 2.5 months in the rehabilitation unit, she was discharged with a persistent severe receptive and expressive aphasia, as well as a dense right hemiparesis. She is now living at home with community supports.
