Review[Near infrared spectroscopy monitoring in the neurointensive care].
Near infrared spectroscopy (NIRS) can noninvasively measure cerebral saturation in oxygen, that permits to estimate brain oxygenation and metabolism. This technique could be incorporated into a multimodal monitoring for severely brain-injured patients. This review presents the principles of NIRS, its limits, the main results from clinical studies and its perspectives. More clinical studies are needed before recommending the routine use of NIRS in the ICU.

Review[EEG in intensive care unit: which indications, which material?].
There is a growing development of continuous EEG monitoring (cEEG) in the intensive care unit (ICU) management of neurological patients. Its main objective is the detection of epileptic seizures or status epilepticus because the sensitivity of standard short-duration EEG recording in the ICU is poor. The aim of monitoring is to allow rapid recognition and treatment of epileptic complications in order to decrease secondary insults to the brain and improve outcome. ⋯ Another application of EEG in the ICU is monitoring depth of anaesthesia or barbiturate treatment. Due to artifacts contamination, this is possible only in deeply sedated of paralyzed patients. The impact or cEEG monitoring on clinical management and its indications have to be further defined.

Review[Non-invasive evaluation of intracranial pressure: how and for whom?].
The invasive monitoring of intracranial pressure is useful in circumstances associated with high-risk of raised intracranial pressure. However the placement of intracranial probe is not always possible and non-invasive assessment of intracranial pressure may be useful, particularly in case of emergencies. Transcranial Doppler measurements allow the estimation of perfusion pressure with the pulsatility index. Recently, new ultrasonographic methods of cerebral monitoring have been developed: the diameter of the optic nerve sheath diameter, a surrogate marker of raised intracranial pressure and the estimation of median shift line deviation.

Review[Awake surgery for brain gliomas: plea for an increased involvement of anesthesiologists].
The recent development of awake surgery in neuro-oncology allowed a conceptual change, i.e. the realization of resection for invasive brain tumors according to functional and not anatomic boundaries. This paradigmatic shift enabled a significant improvement of results in surgery for gliomas, by opening the door to resections within eloquent areas classically considered as "inoperable", while preserving and even improving the quality of life of patients. In addition, the extent of resections has been maximized, leading to an increase of median survival - especially in low-grade gliomas. ⋯ Thus, it seems important that anesthesiologists can benefit from a clear and accurate knowledge of the real contribution of this procedure, in order to better evaluate the balance between the theoretical risks of surgery under local anesthesia versus the actual risk of not performing resection with a maximum of safety and efficiency for the patients. The purpose of this plea is to advocate the spread of awake surgery in routine practice, due to its major impact on both functional and survival outcomes, by nonetheless keeping in mind that a multidisciplinary staff is mandatory for selection of patients as well as into the operating room. In this state of mind, anaesthesiologists have to play a central role, through an increased involvement in this field.
