Subarachnoid hemorrhage (SAH) frequently results in severe morbidity, even mortality. Hypothermia is known to have a neuroprotective effect in ischemic injuries. The aim of this study was to determine whether nasopharyngeal (NP) perfluorochemical (PFC) cooling could be used in a rat model of SAH model for neuroprotection. ⋯ The data from this study indicate that local hypothermia by NP-PFC cooling supports return of CBF and neuronal integrity and suppresses the inflammatory response in SAH, suggestive of a promising neuroprotective approach in management of SAH.

To evaluate the combined effects of a decompressive craniectomy and prolonged selective brain hypothermia on large hemispheric infarction in a rat model. ⋯ A decompressive craniectomy reduced the infarct volume and improved the neurologic outcomes in a rat model of middle cerebral artery infarction. Furthermore, when combined with prolonged selective brain hypothermia, significant additional benefits were observed for the neurologic outcomes, infarct volume, and degree of neuroinflammation.
