ICU patients may be offered sedation without necessarily compromising arousal or cognition. Alleviation of anxiety and agitation can singly and effectively improve mental engagement and performance if overt forebrain dysfunction is avoided. Higher ACE scores with DEX may be a consequence of the intellect-sparing yet calming effect of this drug.

Patients with lower GCS, higher IVH severity, and lower ICH volume are more likely to have an EVD placed. EVD placement is associated with reduced mortality and improved short-term outcomes in patients with IVH after adjusting for known severity factors. EVD use should be protocolized in clinical trials of ICH management where IVH is included.
