Postischemic sevoflurane offers no additional neuroprotective benefit to preischemic dexmedetomidine.
We designed this study to determine whether a combination of dexmedetomidine and sevoflurane postconditioning provides additive neuroprotection in a rat model of transient global cerebral ischemia. ⋯ A combination of preischemic dexmedetomidine and sevoflurane postconditioning provides no additional neuroprotective benefit over preischemic dexmedetomidine or sevoflurane postconditioning alone.

Accuracy of end-tidal CO2 measurement through the nose and pharynx in nonintubated patients during digital subtraction cerebral angiography.
To determine the accuracy of end-tidal CO2 (PETCO2) obtained in the nose through the Smart CapnoLine and in the pharynx through the modified Filterline H Set with supplemental oxygen at 5 L/min in nonintubated patients undergoing digital subtraction cerebral angiography (DSA). ⋯ In a clinical setting, end-tidal CO2 measurements sampled from the nose and the pharynx were accurate and reliable in nonintubated patients with a nasopharynx airway in place during DSA.
