Coinfusion of dextrose‐containing fluids and red blood cells does not adversely affect in vitro red blood cell quality
Bibliographic record
Abstract
BACKGROUND: Transfusion guidelines advise against coinfusing red blood cells (RBCs) with solutions other than 0.9% saline. We evaluated the impact of coinfusion with dextrose-containing fluids (DW) on markers of RBC quality. STUDY DESIGN AND METHODS: A pool-and-split design was used to allow conditions to be tested on each pool within 2 hours of irradiation. Three pools at each storage age (5, 14, and 21 days) were created for each phase. In Phase 1, samples were infused through a neonatal transfusion apparatus alone or with treatment solutions: D5W, D10W, D5W/0.2% saline, and 0.9% saline. In Phase 2, samples were incubated alone or in a 1:1 ratio with treatment solutions and tested after 5, 30, and 180 minutes. Hemolysis, supernatant potassium, RBC indices, morphology, and deformability were measured on all samples. RESULTS: In Phase 1, RBCs transfused alone through the apparatus had higher (p<0.01) hematocrit, total hemoglobin, and supernatant potassium compared to all other groups. No statistical differences were identified between groups for other measured variables. In Phase 2, mean corpuscular volume of all samples containing DW increased with incubation length and were higher (p<0.01) than RBCs incubated alone or with 0.9% saline after 30 and 180 minutes. RBCs incubated with D5W and D5W/0.2% saline had greater (p<0.05) hemolysis than RBCs alone after 180 minutes. CONCLUSION: In vitro characteristics of RBCs coinfused with 0.9% saline or D10W were not adversely impacted. When developing clinical studies in neonates, we recommend use of D10W and a transfusion apparatus that minimizes the contact volume of the coinfusate with the RBC.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
