Seizures after epidural blood patch with undiagnosed subdural hematoma
Bibliographic record
Abstract
OBJECTIVE: We present a case of new-onset seizures in a parturient who received an epidural blood patch (EBP) in the presence of an undiagnosed cerebral subdural hematoma. We review the relevant literature and examine the implications for management. CASE REPORT: A 33-year-old parturient developed symptoms of postdural puncture headache 16 hours after initiation of epidural analgesia for labor. On the third postpartum day, she likely had an unwitnessed and unrecognized seizure. Presenting to hospital with headache and fatigue, she received an EBP. Forty-five minutes after the EBP, she had a generalized seizure followed by another 2 hours later. Imaging revealed a small cranial subdural hematoma. She had no further seizures, her headache improved, and she was discharged home on postpartum day 5. CONCLUSIONS: We believe that the subdural hematoma and not the EBP was the cause of the seizures. Earlier recognition of confusion and fatigue as a postictal state may have led to earlier diagnosis of the hematoma. Our experience suggests that EBP be avoided in the setting of subdural hematoma.

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.
