Management of Prenatally Diagnosed Tracheal Obstruction: Access to the Airway in Utero Prior to Delivery
Bibliographic record
Abstract
A fetus of 23-weeks gestation presented with polyhydramnios, and was found on sonography to have a large anterior cervical teratoma. At 26 weeks the mother went into premature labor and the membranes ruptured; at this time the uterus was of 32-weeks size secondary to polyhydramnios. A cesarean section was performed through a low transverse uterine incision, and the fetal head and shoulders were delivered with the cord intact. An endotracheal tube was placed, and the cord was then divided. The baby was taken to the neonatal intensive care unit for stabilization prior to planned resection, but suffered pharyngeal hemorrhage followed by endotracheal tube dislodgement several hours after birth, and expired. Despite an unfortunate outcome, this case illustrates the feasibility and potential value of in utero airway access in cases of prenatally diagnosed tracheal obstruction.

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.
