How I Do It: Technical report on surgically-initiated rectus sheath catheter using catheter-over-needle assembly.
Bibliographic record
Abstract
Development of chronic postsurgical pain following major abdominal or pelvic surgeries is increasingly recognized. Multimodal analgesia including regional anesthesia such as rectus sheath block is growing in popularity. While the literature mainly describes ultrasound-guided rectus sheath blocks, there are many advantages to surgically-initiated rectus sheath catheter performed at the end of surgery. In this technical description, we describe the rationale and technique of surgical insertion of rectus sheath catheters following major urologic surgery with midline incision which is routinely performed by urologists at our institution. Furthermore, we would like to highlight the type of catheter used during rectus sheath catheter insertion, namely the catheter-over-needle assembly. It is simple to insert while minimizes complications such as local anesthetic leakage at the insertion site causing dressing disruption and premature catheter dislodgement, as the catheter-over-needle assembly fits snugly with the skin after insertion.

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.
