Sodium Bicarbonate Use in Shock and Cardiac Arrest
Bibliographic record
Abstract
OBJECTIVES: To evaluate the preferences and self-reported practices of pediatric acute care physicians with respect to sodium bicarbonate administration to infants and children in shock or cardiac arrest. DESIGN: National survey study utilizing a self-administered questionnaire. SETTING: Thirteen Canadian pediatric tertiary care centers. SUBJECTS: Canadian pediatric critical care physicians, pediatric emergency physicians, and trainees in these subspecialties. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Survey items were evaluated based on Yes/No responses, frequency responses, and Likert scales. Overall response rate was 53% (151/284) with 49.0% (74/151) citing pediatric critical care as their primary practice. 82.0% of respondents (123/150) indicated they would administer sodium bicarbonate as part of ongoing resuscitation for septic shock, whereas 58.3% (88/151) would administer sodium bicarbonate in a cardiac arrest scenario (p=0.004). 47.3% (71/150) selected a pH threshold at or below which they would administer sodium bicarbonate (mean, 6.94±0.013; median, 7.00; range, 6.50-7.20; interquartile range, 6.90-7.00), whereas 20.5% (31/151) selected a base excess threshold (mean, -15.62±0.78; median, -16; range, -20 to -4; interquartile range, -20 to -14). Both pH and duration of resuscitation were strongly associated with the decision to administer sodium bicarbonate (p<0.0001). Respondents' perceptions regarding a colleague's likelihood of administering sodium bicarbonate to the same patient under the same circumstances reflect an acknowledgment of disparate practices with respect to sodium bicarbonate use. 53.0% (79/149) felt current American Heart Association guidelines help them in deciding whether to administer sodium bicarbonate to critically ill patients, and 84% would support a randomized trial. CONCLUSION: Differences of opinion exist among pediatric acute care physicians with respect to the timing and appropriateness of sodium bicarbonate administration during resuscitation. Most indicated they would support moving forward with a clinical trial.

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.
