A Prospective Study of Post-cesarean Delivery Hypoxia After Spinal Anesthesia With Intrathecal Morphine 150 μg
Bibliographic record
Abstract
(Int J Obstet Anesth. 2017;32:48–53) Neuraxial morphine is one of the most common postoperative analgesia techniques for women who have undergone cesarean delivery. Delayed respiratory depression is a concerning side effect of intrathecal morphine (ITM), as it can potentially increase morbidity and mortality. While the incidence of bradypnea associated with ITM has been reported to be 0.25% or lower, this rate may not account for all cases of ITM-induced respiratory depression because respiratory rate was not continuously monitored in the studies from which these rate were calculated. In addition, patients may develop hypoxia or hypercarbia without the presence of bradypnea. This study aimed to analyze the incidence and timing of hypoxic events in patients receiving post-cesarean analgesia in the form of ITM 150 μg, in order to better define populations at risk of developing hypoxia following ITM.

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.
