Foreword

The care of critically ill patients with neurological diseases is challenging, and often involves compromises to select a least-worst rather than a best option. This is particularly true in the case of neuromonitoring. Clinical monitoring of brain function in our patients is often confounded by sedative drugs, and we have to rely to a greater extent on neuroimaging and bedside monitoring devices. Imaging essentially provide snapshots of disease, rather than representing an approach to ongoing patient monitoring. As a consequence, many neuro-­ ICUs have had to primarily rely on multimodality physiological monitoring (intracranial pressure monitoring, often combined with brain oximetry and cerebral microdialysis) to understand evolving pathophysiology, select appropriate therapies, and assess their impact. However, the risks involved make their use inappropriate in patients with less severe disease, in the prehospital phase, when patients are being screened before ICU admission, and after patients have left the ICU. Finally, substantial cost of disposable equipment limits their use in resource-limited contexts. There is a clear
