Association between 4%‐tetrasodium EDTA and sepsis in neonatal piglets: A retrospective cohort study
Bibliographic record
Abstract
BACKGROUND: Central line-associated bloodstream infections are a major concern for children with intestinal failure and in animal research using parenteral nutrition (PN). In neonatal piglets receiving PN, we compared sepsis, line occlusions, line replacements, mortality, and costs with and without the use of a 4%-tetrasodium ethylenediaminetetraacetic acid (T-EDTA) locking solution. METHODS: We performed a retrospective review of piglets with a central venous jugular catheter enrolled in 14-day exclusive PN (TPN) trials or in 7-day short bowel syndrome (SBS) trials, before and after initiation of T-EDTA. Lines were locked with a 1-ml solution for 2 h daily (T-EDTATPN, n = 17; T-EDTASBS, n = 48) and compared with our prior standard of care using 1.5-ml heparin flushes twice daily (CONTPN, n = 34; CONSBS, n = 48). Line patency and signs of sepsis were checked twice daily. Jugular catheters were replaced for occlusions whenever possible. Humane end points were used for sepsis not responding to antibiotic treatment or unresolved catheter occlusions. RESULTS: Compared with CON, sepsis was reduced using T-EDTA, significantly for TPN (P = 0.006) and with a trend for SBS piglets (P = 0.059). Line occlusions necessitating line changes were reduced 15% in TPN studies (P = 0.16), and no line occlusions occurred for T-EDTA SBS piglets. CONCLUSION: In our neonatal piglet research, use of T-EDTA locking solution decreased sepsis and, although not statistically significant, reduced occlusions requiring line replacements. Given the expense of animal research, adding a locking solution must be cost-effective, and we were able to show that T-EDTA significantly reduced total research costs and improved animal welfare.

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.
