Temperature profile and outcomes of neonates undergoing whole body hypothermia for neonatal hypoxic-ischemic encephalopathy
Bibliographic record
Abstract
BACKGROUND: Decreases below the target temperature were noted among neonates undergoing cooling in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network Trial of whole body hypothermia for neonatal hypoxic-ischemic encephalopathy. OBJECTIVE: To examine the temperature profile and impact on outcome among ≥ 36 wk gestation neonates randomized at ≤ 6 hrs of age targeting an esophageal temperature of 33.5°C for 72 hrs. DESIGN, SETTING, PATIENTS: Infants with intermittent temperatures recorded of <32.0°C during induction and maintenance of cooling were compared to all other cooled infants, and the relationship with outcome at 18 months was evaluated. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: There were no differences in the stage of encephalopathy, acidosis, or 10 min Apgar scores between infants with temperatures of <32.0°C during induction (n = 33) or maintenance (n = 10) and all other infants who were cooled (n = 58); however, birth weight was lower and the need for blood pressure support higher among infants with temperatures of <32.0°C compared to all other cooled infants. No increase in acute adverse events was noted among infants with temperatures of <32.0°C, and hours spent at <32°C was not associated with the primary outcome of death or moderate/severe disability or the Bayley II Mental Developmental Index at 18 months. CONCLUSIONS: Term infants with a lower birth weight are at risk for decreasing temperatures of <32.0°C while undergoing body cooling using a servo-controlled system. This information suggests extra caution during the application of hypothermia as these lower birth weight infants are at risk for overcooling. Our findings may assist in planning additional trials of lower target temperature for neonatal hypoxic-ischemic encephalopathy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
