Interstitial Fluid Pressure in Free Vascularized Skin Flaps of the Rat Epigastrium
Bibliographic record
Abstract
The purpose of this study was to observe the magnitude and time course of changes in tissue edema in experimental free flaps. Thirty female Sprague Dawley rats underwent elevation and orthoptic transplantation of free epigastric skin flaps. Using a modified "wick in needle" technique, interstitial fluid pressure (IFP) was measured in the flaps at various times up to 2 weeks postoperatively. Increases in IFP to positive values were seen by 12 hours. IFP remained elevated for 3 to 5 days, after which they gradually returned to control values by 2 weeks. This is the first study to follow the time course and magnitude of changes in IFP and edema in free flaps. It is a useful animal model by which the hemodynamic effects of physical and pharmacological manipulation of flaps can be studied.

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.
