Favourable neurological outcomes following delivery room cardiopulmonary resuscitation of infants ≤ 750 g at birth
Bibliographic record
Abstract
OBJECTIVE: To study short- and long-term outcomes of infants < or = 750 g birthweight who received cardiopulmonary resuscitation (CPR) in the delivery room. METHODOLOGY: A retrospective analysis of all inborn live births < or = 750 g birthweight from 1990 to 1996. Cardiopulmonary resuscitation was defined as positive pressure ventilation via an endotracheal tube and chest compressions. Univeriate analysis were conducted comparing patients according to the use of CPR or positive pressure ventilation alone. RESULTS: Cardiopulmonary resuscitation was administered to 16 infants: four received chest compressions only and 12 also received adrenaline. Cardiopulmonary resuscitation recipients had significantly lower Apgar scores at both 1 and 5 min, and had delayed onset of spontaneous respiration (P < 0.01). Seven patients died, and eight of nine survivors were free of major neurodevelopmental abnormalities at follow up. All CPR recipients with a 5 min Apgar score of < or = 5 and delayed onset of spontaneous respiration beyond 5 min had poor outcomes. CONCLUSION: Contrary to the majority of published evidence, delivery room CPR in our extremely small infants was not associated with a high risk of severe neurodevelopmental disability.

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.
