Viability of AS‐3 and SAG‐M red cells stored in plastic syringes for pediatric transfusion
Bibliographic record
Abstract
BACKGROUND: Pediatric patients may require small-volume transfusions necessitating splitting of red cell (RBC) units. This process usually involves temporary storage of aliquots in pediatric blood bags or, in some cases, plastic syringes, until they are transfused. While many studies have been published on the efficacy of storage in blood bags, there is little evidence to show that RBCs are safe and effective for transfusion after separation into plastic syringe aliquots. STUDY DESIGN AND METHODS: Donor RBC units, stored in either SAG-M (n = 10) or AS-3 additive (n = 11), were split into transfer bags and plastic syringes and stored at either 4 degrees C or room temperature (RT). Half of the aliquots were also irradiated at 25 Gy. RBCs were monitored after 0, 4, and 24 hours of storage with the following variables to assess cellular function and viability: adenosine triphosphate, percent hemolysis, hematocrit, pH, lactate dehydrogenase, extracellular potassium, sodium, and RBC indices. RESULTS: There was no difference found between irradiated and nonirradiated aliquots or aliquots stored in the refrigerator versus those stored at RT. Significant differences between aliquots stored in approved transfer bags and those stored in syringes were not identified. CONCLUSIONS: Irradiation and storage of aliquoted RBCs demonstrated expected but not significant changes in the in vitro variables. Storage for up to 24 hours in syringes does not have a greater detrimental effect on RBCs than storage in transfer bags, making products stored in either container safe for transfusion to pediatric patients.

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.
