External ventricular drain (EVD) is a standard way for both monitoring intracranial pressure (ICP) and draining cerebrospinal fluid (CSF) for aneurysmal subarachnoid hemorrhage (aSAH) patients. In our recent published paper, we found great variations in clinical practice of bedside ICP monitoring through EVD. This commentary describes the current problems with EVD practices and depicts future trends of cerebral monitoring for aSAH patients. We believe a monitoring system that meet the three criteria: continuous and precise; multimodal and noninvasive; personalized and predictive is promising in the advancement of neurointensive care of patients with aSAH.
