Central Diabetes Insipidus
Diabetes insipidus (DI) is a condition caused by loss of the effect of antidiuretic hormone on the collecting ducts of the kidneys, resulting in loss of free water.

Lund Concept for Traumatic Brain injury
A 'volume-targeted' approach to the management of TBI developed by a Swedish group (not ABBA), based on physiological volume regulation of the intracranial compartments. The Lund concept contradicts the prevailing strategem of titrating CPP to match ICP in TBI
Temperature and Traumatic Brain Injury
Temperature and TBI. Induced hypothermia has been used for years to reduced cerebral metabolic rate; manipulation of temperature has been shown to effect certain types of brain injury (therapeutic hypothermia in out-of-hospital cardiac arrest).
Polyuria and Traumatic Brain Injury
polyuria following TBI is common; multiple causes, some of which imply a poor prognosis. Goal is to identify and treat the cause and any complications
Brain Impact Apnoea
Brain impact apneoa is an under-appreciated cause of morbidity and mortality in traumatic brain injury (TBI)
Limitations of CT in Traumatic Brain Injury
Limitations of CT head scan in Traumatic Brain Injury (TBI)
Cerebral Perfusion Pressure in TBI
Cerebral Perfusion Pressure (CPP) in Traumatic brain injury (TBI). Cerebral Perfusion Pressure (CPP) = MAP – ICP or CVP (whichever is highest)
External Ventricular Drain
External Ventricular Drain (EVD): ICP monitor than allows CSF drainage; measurement and treatment of raised ICP
Base of Skull Fracture
Base of Skull Fracture: fracture involving the floor of the cranial vault
Increased Intracranial Pressure in TBI
Increased Intracranial Pressure in TBI; normal ICP 7-15mmHg
sustained increases > 20mmHg is associated with ischaemic brain injury
Extradural ICP monitors
Extradural ICP monitor: ICP monitoring; catheter inserted though a burr hole but does not penetrate the dura
Codman ICP Monitor
Codman ICP Monitor: intracranial pressure monitor (aka 'BOLT')
