Clinical and laboratory assessment of hydration status of neonatal calves with diarrhea
Open accessAbstract
OBJECTIVE: To develop accurate, objective guidelines for assessing hydration status of neonatal calves with diarrhea. DESIGN: Prospective study. ANIMALS: 15 male dairy calves 3 to 10 days old. PROCEDURE: Dehydration and diarrhea were induced by administration of diuretic agents (i.e., furosemide, spironolactone, hydrochlorothiazide) and sucrose solution. Linear regression was used to examine the relationship between potentially useful factors for evaluating hydration status (extent of enophthalmos; skin-tent duration on neck, thorax, and upper and lower eyelids; heart rate; mean central venous pressure; peripheral [extremity] and core [rectal] temperatures; core-peripheral [rectal-extremity] temperature difference; PCV; and hemoglobin and plasma protein concentrations) and degree of dehydration, as determined by change in body weight. RESULTS: Best predictors of degree of dehydration were extent of enophthalmos, skin elasticity on neck and thorax, and plasma protein concentration. CLINICAL IMPLICATIONS: These experimentally determined guidelines provide practitioners with a simple, inexpensive, and practical method for evaluating hydration status of neonatal calves with diarrhea.

Serum total protein concentration was greater after a longer journey than after a shorter one, and this could indicate greater dehydration after a longer journey.
“In addition, their serum total protein concentration was greater after a longer journey than after a shorter one, and this could indicate greater dehydration (Constable et al., 1998) after a longer journey.”

The estimates provided by Constable et al. (1998) suggest that the results obtained in the current study for the measures of dehydration were consistent and not indicative of severe dehydration.

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.
