Effects of rapid intravenous 100%<scp>L</scp>‐isomer lactated Ringer's administration on plasma lactate concentrations in healthy dogs
Bibliographic record
Abstract
OBJECTIVE: To determine if rapid intravenous administration of lactated Ringer's solution containing 28 mmol/L of l-lactate (L-LRS) can result in an increase in plasma lactate concentration in healthy dogs. DESIGN: Prospective cross over study with a 4-week washout period. SETTING: Veterinary teaching hospital. ANIMALS: Six healthy adult Beagles. INTERVENTIONS: Dogs received 180 mL/kg/h of L-LRS over 60 minutes, followed by a 4-week washout period, then 180 mL/kg/h of 0.9% sodium chloride (NaCl) over 60 minutes. MEASUREMENTS AND MAIN RESULTS: Blood samples were drawn at baseline (T0), every 10 minutes during fluid administration (T10 to T60), and 60 minutes after fluid administration (T120). Samples were measured in duplicate at all time points with a handheld meter and at T0, T60, and T120 with a blood gas analyzer. Data were analyzed with 1-way or 2-way ANOVA for repeated measures and post hoc tests with Dunnett's or Bonferroni's correction for within-group and between group analyses, respectively. P values < 0.05 were considered significant. Results are mean ± SD. There was no difference between groups at T0 (L-LRS = 1.1 ± 0.6 mmol/L, NaCl = 1.2 ± 0.9 mmol/L). Within the L-LRS group, T0 was significantly lower than all other time points except T120. At T50 and T60, the L-LRS group was higher than the NaCl group. There was a statistical significance between the 2 groups over time. CONCLUSIONS: The rapid administration of intravenous L-LRS to healthy dogs significantly increases plasma lactate concentration within 10 minutes and returns to baseline values within 60 minutes after cessation of administration. This could have implications in how plasma lactate concentration is interpreted with respect to prognosis, particularly in patients receiving resuscitative rates of L-LRS. Interpretation of plasma lactate concentrations should be considered in light of the rate, quantity and type of fluid administered, and timing of blood samples.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
