Circulating Catecholamines and Sympathetic Activity after Head Injury
Abstract
Plasma norepinephrine (NE) and dopamine beta-hydroxylase (DBH) levels were measured during the first 7 days after head injury in 48 patients. Blood pressure, pulse, temperature, and Glasgow coma score (GCS) were recorded at the time of sampling for each patient, and the relationships of these to NE and DBH were examined. In patients with multiple trauma, NE levels were usually elevated, regardless of the GCS. In patients with head injury alone, however, NE was proportional to GCS. Alert patients after a brief loss of consciousness (GCS, 14) had normal NE levels. Those in coma had levels as high as 7 times normal. Blood pressure, pulse, and temperature were found to be elevated proportionally to elevations in plasma NE in patients with head injury. The finding of elevated plasma NE in patients with severe head injury raises the possibility of adverse effects of sympathetic hyperactivity in patients with severe head injury, including hypermetabolism, cardiovascular abnormalities, and direct effects of catecholamines on the damaged central nervous system.

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.
