Autoregulation of cerebral blood flow after experimental fluid percussion injury of the brain
Abstract
✓ To test the hypothesis that concussive brain injury impairs autoregulation of cerebral blood flow (CBF), 24 cats were subjected to hemorrhagic hypotension in 10-mm Hg increments while measurements were made of arterial and intracranial pressure, CBF, and arterial blood gases. Eight cats served as controls, while eight were subjected to mild fluid percussion injury of the brain (1.5 to 2.2 atmospheres) and eight to severe injury (2.8 to 4.8 atmospheres). Injury produced only transient changes in arterial and intracranial pressure, and no change in resting CBF. Impairment of autoregulation was found in injured animals, more pronounced in the severe-injury group. This could not be explained on the basis of intracranial hypertension, hypoxemia, hypercarbia, or brain damage localized to the area of the blood flow electrodes. It is, therefore, concluded that concussive brain injury produces a generalized loss of autoregulation for at least several hours following injury.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
