There are a number of recognised causative factors including head trauma, hypothermia and iatrogenic factors such as pharmacological agents and permissive cooling. We describe a case of a 19-year-old man with a severe traumatic brain injury. In a 36-h period, his intracranial pressure increased despite maximal medical therapy and he developed refractory hypokalaemia. Immediately following a decompressive craniectomy, the patient was noted to be profoundly hyperkalaemic; this led to the development of ventricular tachycardia and cardiac arrest, from which the patient did not recover. The effects of brain injury on potassium balance are not well appreciated; the effect of decompressive craniectomy on potassium (K<jats:sup>+<\/jats:sup>) balance has not been described previously. We would like to emphasise the potential effect of diffuse axonal injury, a severe form of brain injury and decompressive craniectomy on potassium balance.<\/jats:p>","DOI":"10.1136\/bcr-01-2012-5654","type":"journal-article","created":{"date-parts":[[2012,10,11]],"date-time":"2012-10-11T10:48:36Z","timestamp":1349952516000},"page":"bcr0120125654","source":"Crossref","is-referenced-by-count":4,"title":["Dyskalaemia
