To describe a technique for the induction of hypothermia and its complications for the treatment of acute ischemic stroke. ⋯ Surface cooling for the treatment of acute ischemic stroke can be performed rapidly with early neuromuscular paralysis. Advanced age and prolonged hypothermia may be associated with an increased risk of complications.

A common observation in closed head injuries is the contrecoup brain injury. As the in vivo brain is less dense than the cerebrospinal fluid (CSF), one hypothesis explaining this observation is that upon skull impact, the denser CSF moves toward the site of skull impact displacing the brain in the opposite direction, such that the initial impact of the brain parenchyma is at the contrecoup location. ⋯ The pattern of brain injury in which the contrecoup injury is greater than the coup injury is a result of initial movement of the brain in the contrecoup location. During the process of closed head injury, the brain parenchyma is initially displaced away from the site of skull impact and toward the contrecoup site resulting in the more severe brain contusion.

Fever is common and difficult to control in patients with subarachnoid hemorrhage (SAH). We have previously shown an inverse relationship between fever and outcome in patients with SAH. ⋯ We have demonstrated that fever can be safely and effectively controlled in patients with SAH for at least 24 hours using an ICC. Future studies are needed to assess the effect of such sustained therapy on outcome in patients with SAH.

The ICH score is a clinical grading scale that is composed of five components related to outcome after nontraumatic intracerebral hemorrhage (ICH): Glasgow Coma Scale score, ICH volume, presence of intraventricular hemorrhage, infratentorial origin, and age. The ICH score accurately risk-stratifies patients in the cohort from which it was developed, but it has not yet been fully externally validated. The purpose of this study was to determine whether the ICH score accurately risk-stratifies patients in an independent cohort. ⋯ The ICH score accurately stratifies outcome in an external patient cohort. Thus, the ICH score is a validated clinical grading scale that can be easily and rapidly applied at ICH presentation. Ascale such as the ICH score could be used to standardize clinical treatment protocols or clinical studies.
