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.

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.
