[en] Intracranial hypertension is one of the major causes of secondary injury in traumatic brain injury leading to a significant burden of morbidity and mortality. We here present a review of available therapies for the treatment of refractory intracranial hypertension that is defined as an intracranial hypertension that does not respond to the firstline therapies. Second-line therapies that are available for the treatment of refractory intracranial hypertension include mild induced hypothermia, inotropes, and vasopressors for the control of cerebral perfusion pressure, transient hyperventilation, barbiturates, and decompressive craniectomy. Apart from decompressive craniectomy, these therapies are supported by the last guidelines published by the Brain Trauma Foundation (BTF). However, the level of evidence supporting them is low to moderate. This is probably partly explained by the fact that traumatic brain injury is extremely heterogeneous and requires multimodal and individualised care, which makes randomised clinical trials difficult to set up. On-going studies like those conducted on induced hypothermia (EUROTHERM3235) and on decompressive craniectomy (RESCUEicp) may lead to new perspectives for the management of patients suffering from refractory intracranial hypertension.
