Neurocritical care
-
Patients with acute brain injury but normal lung function are often intubated for airway protection, but extubation often fails. Currently, no clinical data exist that describe the events leading to extubation failure in this population. We examined the extubation failure rate, reintubation rate, and clinical characteristics of patients whose reason for intubation was a primary neurological injury. We then identified the clinical characteristics of those patients with primary brain injury who were reintubated. ⋯ The extubation failure rate in our neurocritical care unit is low. In patients with encephalopathy and primary brain injury who were reintubated, respiratory distress caused by altered mental status was the most common cause of reintubation. These patients demonstrated signs disrupted ventilation usually with periods of prolonged hypoventilation. Increased work of breathing from lung injury due to pneumonia or aspiration was not the most common cause of reintubation in this population.

Case Reports
The "cord sign" in cerebral venous thrombosis associated with high plasma levels of factor VIII.
Cerebral venous thrombosis (CVT) is a potentially life-threatening condition that requires acute recognition and treatment. Diagnosis of CVT is challenging and requires a high index of clinical suspicion. The finding of the "cord sign" in a non-contrast cranial CT is useful for the rapid recognition of CVT in the emergency setting. ⋯ We report the first case of CVT with the "cord sign" and concomitant elevated FVIII. Early recognition of the "cord sign" is warranted for the emergency diagnosis and treatment of CVT.
