Effect of continuous femoral nerve block versus patient controlled intravenous analgesia on rehabilitation following total knee arthroplasty
Bibliographic record
Abstract
Objective To compare the effect of continuous femoral nerve block (CFNB) with patient controlled intravenous analgesia (PCIA) on pain relief, rehabilitation efficacy, satisfaction degree following total knee arthroplasty (TKA) in an attempt to find a safe and effective analgesia at the stage of rehabilitation. Methods The records of 116 patients undergone unilateral TKA for osteoarthritis or rheumatoid arthritis of the knee were evaluated. The patients with preoperative American Society of Anesthesiology (ASA) score of 1 to 3 were randomized into CFNB group (58 cases) and PCIA group(58 cases) according to the random number table. Both operations were performed under ultrasound guidance. Postoperative visual analogue score (VAS), knee function, incidence of adverse reaction, and satisfaction degree were compared between the two groups. Results Regardless of the score at postoperative 4 and 12 hours, VAS between CFNB and PCIA groups revealed significant differences at postoperative 24 [(3.2±1.1)points vs (4.1±1.5)points], 48 [(3.4±1.2)pointsvs (4.1±1.0) points] and 72 hours [(3.3±1.2)pointsvs (4.0±1.1)points] ( all P<0.05). Time to achieve knee rehabilitation training objectives like straight leg raise, walking with crutches, and passive bending to 90°were similar between the two groups. Both groups achieved comparable knee function status with respect to Hospital for Special Surgery (HSS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and maximal knee flexion angle at postoperative 3 months. Postoperative nausea and vomit were significantly more frequent in PCIA group (24%) than in CFNB group (14%) ( all P<0.05), but patients in both groups were satisfactory. Conclusion Ultrasound guided CFNB is an effective analgesic method during the early stage of TKA, for it can control pain, accelerate rehabilitation training and function recovery, reduce adverse reaction as well as improve patients' satisfaction. Key words: Arthroplasty, replacement, knee; Pain; Continuous femoral nerve block/patient controlled intravenous analgesia

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.
