Neurocritical care

Clinical applications of dexmedetomidine (DEX) for neurosurgical procedures have not been adequately investigated. This study aimed to test the use of DEX infusion, alone or as an adjunct to propofol infusion, as compared to propofol infusion in patients with an unruptured cerebral aneurysm after uneventful intracranial procedures. ⋯ DEX could be used safely for both intubated and extubated patients following uneventful intracranial procedures for an unruptured cerebral aneurysm, though it significantly reduced HR. Our findings also indicate that it is preferable to add low-dose propofol to DEX for management of intubated patients.

Cerebral edema and raised intracranial pressure are common problems in neurological intensive care. Osmotherapy, typically using mannitol or hypertonic saline (HTS), has become one of the first-line interventions. However, the literature on the use of these agents is heterogeneous and lacking in class I studies. The authors hypothesized that clinical practice would reflect this heterogeneity with respect to choice of agent, dosing strategy, and methods for monitoring therapy. ⋯ Treatment of cerebral edema using osmotically active substances varies considerably between practitioners. This variation could hamper efforts to design and implement multicenter trials in neurocritical care.
