This study investigated the efficacy of continuous fascia iliaca compartment block (CFICB) in perioperative management.Methods: A retrospective analysis was conducted on elderly patients (≥ 65 years) with intertrochanteric fractures treated between January 2020 and December 2023. Eligible patients were initially divided into CFICB (n=46) and routine analgesia (RA, n=64) groups. Propensity score matching with a caliper width of 0.21 was performed, yielding 40 patients in each group for final analysis. Matching variables included age, gender, BMI, and ASA score. Primary outcomes were Visual Analog Scale pain scores, cognitive function assessed through a two-tier protocol (Montreal Cognitive Assessment [MoCA©] screening followed by confirmatory Mini-Mental State Examination-2 [MMSE-2Ⓡ] for positive screens), and functional recovery evaluated using the Harris Hip Score.Results: The CFICB group showed significantly lower VAS scores during the early postoperative period (≤ 72h). This was most notable at 24 hours postoperatively (2.43 ± 0.72 vs 3.45 ± 0.87, P < 0.001). Postoperative cognitive dysfunction rates were significantly lower in the CFICB group. The differences were evident at 6h (10% vs 30%, P = 0.025), 24h (15% vs 35%, P = 0.039), and 72h (5% vs 20%, P = 0.043). Multivariable analysis identified CFICB as an independent protective factor against postoperative cognitive dysfunction (adjusted OR = 0.41, 95% CI: 0.26– 0.65, P < 0.001). Harris Hip Scores at one month postoperatively were significantly higher in the CFICB group (78.56 ± 8.12 vs 72.39 ± 7.65, P = 0.008). Complication rates were comparable between groups (22.5% vs 17.5%, P = 0.576).Conclusion: CFICB effectively improves postoperative pain management, reduces cognitive dysfunction incidence, and enhances early functional recovery in elderly patients with intertrochanteric fractures, while maintaining a favorable safety profile.Keywords: continuous fascia iliaca compartment block, intertrochanteric fracture, cognitive function, postoperative pain, hip joint function, elderly patients, regional anesthesia

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.
