Contribution of unmeasured anions to acid-base disorders and its association with altered demeanor in 264 calves with neonatal diarrhea
Open accessAbstract
BACKGROUND: The quantitative effect of strong electrolytes, unmeasured anions (UAs), pCO2 , and plasma protein concentrations in determining plasma pH and bicarbonate (HCO3 (-) ) can be demonstrated using the physicochemical approach. Demeanor of calves with diarrhea is associated with acidemia, dehydration, and hyper-d-lactatemia. HYPOTHESIS: Unmeasured anions are a major factor influencing changes in plasma pH and HCO3 (-) of calves with diarrhea and UAs and strong UAs, estimated by anion gap (AG) and strong ion gap (SIG), respectively, are more strongly associated with alteration of demeanor compared to other acid-base variables. ANIMALS: A total of 264 calves with diarrhea from two data sets (DS1 and DS2). METHODS: Retrospective study. Forward stepwise regression was performed to determine the relationship between measured pH or HCO3 (-) , and physicochemical variables. A two-way ANOVA was performed to investigate the association between acid-base variables and attitude (bright, obtunded, and stuporous), posture (standing, sternal or lateral recumbency), and strength of suckling reflex (strong, weak, or absent). RESULTS: Increased strong UAs estimated by SIG was the most important contributor to changes in measured pH and HCO3 (-) (DS1: r(2) 66 and 59%, DS2: 39 and 42%, P < .0001). SIG and AG were correlated to deteriorating calf demeanor for all three clinical scoring categories: attitude, posture, and suckle reflex (P < .0001). CONCLUSION AND CLINICAL RELEVANCE: Elevated concentrations of strong UAs were the primary cause of acidemia and had an important influence on the demeanor of calves with diarrhea. These findings emphasize the importance of the calculation of UAs when evaluating acid-base abnormalities in calves.

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.
