Controversies in neurosciences critical care.

Perhaps the greatest recent controversy in the medical management of complex neurologic and neurosurgical patients has been the defining of the optimal care arena. Despite some early skepticism and measured recognition by the ICU community, neurosciences critical care has grown into a well-recognized subspecialty. Within this environment, the diverse expertise of surgeons, neurologists, and anesthesiologists come together to define best therapeutic strategies. Two neurologic disease states that, in particular, continue to elicit expansive interdisciplinary debate are spontaneous intracerebral hemorrhage and aneurysmal subarachnoid hemorrhage.
