Continuous positive airway pressure for term and ≥34+0 weeks’ gestation newborns at birth: A systematic review
Bibliographic record
Abstract
Background Respiratory distress is common during transition after birth, but the effect of continuous positive airway pressure applied in the delivery room has not been systematically evaluated in spontaneously breathing term and ≥34 +0 weeks’ gestation infants. We aimed to compare delivery room continuous positive airway pressure with no delivery room continuous positive airway pressure for term and ≥34 +0 weeks’ gestation newborn infants at birth. Methods Information sources: Medline, Embase, Cochrane Databases, Database of Abstracts of Reviews of Effects, and Cumulative Index to Nursing and Allied Health Literature. The Databases were last searched in October 2021. Eligibility criteria: Randomized, quasi-randomized, interrupted time series, controlled before-after, and cohort studies with English abstracts. Synthesis of results: Two authors independently extracted data, assessed risk of bias, and certainty of evidence. The main outcome was admission to the neonatal intensive care unit (NICU) or higher level of care receiving any positive pressure support. Data were pooled using fixed effects models. Risk of bias: Was assessed using the Cochrane Risk of Bias Tool for randomized trials and the Non-Randomized Studies of Interventions Tool (ROBINS-I) for observational studies. Results In this meta-analysis, two randomized control trials (323 newborns delivered by cesarean section) showed that delivery room continuous positive airway pressure decreased the likelihood of NICU admission (risk ratio (RR) 95% confidence interval (CI) 0.27 (0.11–0.66), p < 0.005) and NICU respiratory support (RR (95% CI) 0.18 (0.05–0.60), p = 0.005) when compared with no delivery room continuous positive airway pressure. However, in two before-after studies (8,476 newborns), delivery room continuous positive airway pressure use was associated with an increased risk of air leak syndrome when compared with no delivery room continuous positive airway pressure. Discussion Certainty of evidence was very low for all outcomes. Among term and ≥34 +0 weeks’ gestation infants having or at risk of having respiratory distress, there is insufficient evidence to suggest for or against routine use of continuous positive airway pressure in the delivery room. Funding: No Funding has been received to conduct this study. Clinical Trial Registration: This systematic review has been registered with the International Prospective Register of Systematic Reviews ( http://www.crd.york.ac.uk/prospero/ ) [identifier: CRD42021225812].

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.
