Prothrombin complex concentrates for oral anticoagulant therapy-related intracranial hemorrhage: a review of the literature.
Warfarin-related intracranial hemorrhage carries a high mortality and poor neurological outcome. Rapid reversal of coagulopathy is a cornerstone of medical therapy to halt bleeding progression; however the optimal approach remains undefined. Prothrombin complex concentrates have promising features that may rapidly reverse coagulopathy, but remain relatively unstudied. ⋯ There is some evidence that PCC may reverse the INR more rapidly compared to fresh frozen plasma. Serious adverse effects were uncommon and included mainly thromboembolism. PCC has features which make it a promising therapy for patients with warfarin-related intracranial hemorrhage, and deserves more rigorous study in prospective-randomized controlled trials.

To describe the concept, implementation, patient characteristics, and preliminary outcomes of a Neonatal Neurocritical Care Service (NNCS) recently established at the University of California, San Francisco. ⋯ While specialized neurocritical care has improved outcomes in adult populations, longitudinal studies are needed to determine whether specialized neurocritical care services will also result in improved neurodevelopmental outcomes for newborns.

The intrinsic pathway of apoptosis has been proposed as one mechanism of cell death after traumatic brain injury (TBI). This study tested the hypothesis that cytochrome c and activated caspase-9 are released into the cerebrospinal fluid (CSF) after severe TBI and that their presence correlates with mitochondrial injury and severity of neurologic outcome. ⋯ We concluded that activated caspase-9 and cytochrome c are present in the CSF of patients with severe TBI. Activated caspase-9 shows weak correlation with poor neurologic outcome.

Brain injury is the leading cause of death in our pediatric ICU [Au et al. Crit Care Med 36:A128, 2008]. ⋯ To induce hypothermia in children comatose after cardiac arrest we target 32-34 degrees C using cooling blankets and intravenous iced saline as primary methods for induction, for 24-72 h duration with vigilant re-warming. The objective of this article is to share our hypothermia protocol for cooling children with acute brain injury.
