Worldwide, different scales are used to assess the clinical condition on admission after aneurysmal subarachnoid hemorrhage. In addition to the prognostic value, the inter-rater variability should be taken into account when deciding which scale preferably should be used. We assessed the interobserver agreement of the commonly used World Federation of Neurological Surgeons, the Hunt and Hess, and the Prognosis on Admission of Aneurysmal Subarachnoid Hemorrhage scales. ⋯ The Hunt and Hess scale showed the lowest interobserver agreement, whereas agreement of the World Federation of Neurological Surgeons and Prognosis on Admission of Aneurysmal Subarachnoid Hemorrhage scales was similar with overlapping CI.

Mass effect of hematoma and the associated perihematomal edema are commonly responsible for neurological deterioration after intracerebral hemorrhage. Efficacy of surgical and medical therapy is limited. We studied the effect of early continuous hypertonic saline infusion on development of perihematomal edema after severe spontaneous supratentorial hemorrhage. ⋯ Early and continuous infusion of hypertonic saline in patients with severe spontaneous intracerebral hemorrhage was feasible and safe. The beneficial effect of this treatment regimen on edema evolution and outcome has to be demonstrated in a controlled trial.

Because the potential neuroprotective effect of isoflurane is controversial, we attempted to study whether isoflurane after treatment provides neuroprotection in a rat model of hyperglycemia-induced ischemic hemorrhagic transformation. ⋯ Isoflurane after treatment worsened physiological and neurological outcomes in this ischemia hyperglycemia-induced hemorrhagic transformation possibly by impairing the antioxidant defense system.
