Femoral Vein Hemostasis in Children Using a Suture‐Mediated Closure Device
Bibliographic record
Abstract
The safety and efficacy of a suture-mediated vascular closure device (Perclose, Abbott, Redwood City, CA) for hemostasis after percutaneous vascular access using >or=8-Fr sheath in the femoral vein after cardiac catheterization in children was assessed. Efficacy was determined by time to hemostasis and vessel integrity, using Doppler vascular ultrasound within 24 hours of the procedure. Forty children were randomized to treatment with either the closure device (n = 20, 10 males, weight 34.8 +/- 21 kg) or manual compression (n = 20, 10 males, weight 33.7 +/- 16 kg, P = 0.57 between groups for weight). Sheath sizes used were >or=8 French (8 Fr, n = 8; 9 Fr, n = 7; 10 Fr, n = 1; 11 Fr, n = 1; 12 Fr, n = 2; and 14 Fr, n = 1). Successful suture deployment was achieved in 14 of the 20 children. Mean time to hemostasis was 6.2 +/- 0.9 versus 14.9 +/- 1.1 minutes in controls (P = 0.003). Five of six unsuccessful deployments were in children with weights <20 kg. There were no differences in the occurrence of vascular complications (i.e., intraluminal thrombus) between the two groups as determined by ultrasound. A suture-mediated device appears safe and effective in achieving rapid vascular hemostasis even after the use of large sheath sizes in children.

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.
