Randomized Controlled Trial
Randomized, double-blind trial of the effect of fluid composition on electrolyte, acid-base, and fluid homeostasis in patients early after subarachnoid hemorrhage.
Hyper- and hyponatremia are frequently observed in patients after subarachnoidal hemorrhage, and are potentially related to worse outcome. We hypothesized that the fluid regimen in these patients is associated with distinct changes in serum electrolytes, acid-base disturbances, and fluid balance. ⋯ Treatment with saline-based fluids resulted in a greater number of patients with hyperchloremia, hyperosmolality, and positive fluid balance >1,500 mL early after SAH, while administration of balanced solutions did not cause more frequent hyponatremia or hypo-osmolality. These results should be confirmed in larger studies.

Randomized Controlled Trial
Increased CSF concentrations of myelin basic protein after TBI in infants and children: absence of significant effect of therapeutic hypothermia.
The objectives of this study were to determine effects of severe traumatic brain injury (TBI) on cerebrospinal fluid (CSF) concentrations of myelin basic protein (MBP) and to assess relationships between clinical variables and CSF MBP concentrations. ⋯ Mean CSF MBP increases markedly after severe pediatric TBI, but is not affected by TH. Infancy and AHT are associated with low MBP concentrations, suggesting that age-dependent myelination influences MBP concentrations after injury. Given the magnitude of MBP increases, axonal injury likely represents an important therapeutic target in pediatric TBI.

Randomized Controlled Trial Multicenter Study
Decompressive hemicraniectomy in malignant middle cerebral artery infarct: a randomized controlled trial enrolling patients up to 80 years old.
Decompressive hemicraniectomy (DHC) has proven efficacious for the treatment of malignant middle cerebral artery infarction (mMCAI) only in patients less than 60 years. This study aimed to assess the effectiveness of DHC in patients up to 80. ⋯ For patients up to 80 years who suffered mMCAI, DHC within 48 h of stroke onset not only is a life-saving treatment, but also increases the possibility of surviving without severe disability (mRS = 5).

Randomized Controlled Trial Comparative Study
Dobutamine-induced high cardiac index did not prevent vasospasm in subarachnoid hemorrhage patients: a randomized controlled pilot study.
Prevention of vasospasm is a challenging issue in subarachnoid hemorrhage (SAH) patients and the objective is to compare high dobutamine-induced cardiac index (CI) and high norepinephrine-induced hypertension for the prevention of vasospasm in SAH patients. ⋯ As compared to norepinephrine-induced hypertension, dobutamine-induced high CI did not reduce the rate of vasospasm in SAH patients. Dobutamine may reduce durations of mechanical ventilation and ICU LOS.

Randomized Controlled Trial
Endovascular cooling and endothelial activation in hemorrhagic stroke patients.
Little is known about endothelial activation under the influence of endovascular temperature management. This analysis was designed to measure the endothelial markers Angiopoietin-1 (Ang-1) and -2 (Ang-2) in endovascularly based prophylactic normothermia versus conventional temperature management. ⋯ Endovascular long-term temperature management did not alter Ang-1 and -2 levels compared to the control group indicating that the endovascular cooling technique itself does not lead to additional endothelial impairment. However, application of NSAIDs led to lower Ang-2 serum concentrations in the endovascular group.
