Delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage is a cause of considerable morbidity and mortality. Magnesium sulfate has been proposed as a prophylactic intervention for angiographic vasospasm and to improve clinical outcomes. A systematic review was conducted to determine the evidence for the prophylactic use of magnesium sulfate in aneurysmal subarachnoid hemorrhage. ⋯ Delayed ischemic neurological deficit has a RR of 0.93 [95 % CI 0.62-1.39]. Transcranial doppler vasospasm has a RR of 0.72 [95 % CI 0.51-1.03]. Current evidence does not support the prophylactic use of magnesium sulfate in aneurysmal subarachnoid hemorrhage.

Risk Factors Associated with Infections and Need for Permanent Cerebrospinal Fluid Diversion in Pediatric Intensive Care Patients with Externalized Ventricular Drains.
Externalized ventricular drains (EVDs) are commonly used in pediatric intensive care units (PICU) but few data are available regarding infection rates, infection risks, or factors associated with conversion to permanent cerebrospinal fluid (CSF) diversion. ⋯ In our large pediatric cohort, EVD infections were associated with longer EVD duration and higher maximum EVD output. Permanent CSF diversion was more likely in patients with higher maximum EVD drainage, longer EVD duration, and younger age.

The natural history and epidemiological aspects of traumatic vertebral artery dissection (VAD) are not fully understood. We determined the prevalence of VAD and impact on outcome of patients with head and neck trauma. ⋯ Although infrequent, VAD in head and neck trauma is associated with higher rates of in-hospital stroke and longer length of ICU stay and total hospital stay. Early diagnosis and endovascular treatment may be an alternative option to reduce the rate of in-hospital stroke in these patients.
