Abstract

Traumatic brain injury, and its management, commonly causes derangements in potassium balance. 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(+)) 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.
