Ultrasound-guided transversus abdominis plane block for elderly herpetic neuralgia located in anterior abdominal wall: a randomized and controlled trial
Bibliographic record
Abstract
Objective To evaluate the efficacy of ultrasound-guided transversus abdominis plane block for elderly herpetic neuralgia located in anterior abdominal wall. Methods A total of 112 elderly patients aged 65-75 years with less than 30 days of herpes zoster neuralgia located in anterior abdominal wall were enrolled for receiving a treatment of transversus abdominis plane block.Patients were randomly allocated into two groups: the control group(n=56)taking gabapentin and celebrex, and the observation group(n=56)receiving transversus abdominis plane block(three times per week for two weeks)as add on therapy to gabapentin and celebrex.Morphine 10 mg was ready for oral application in breakthrough pain.Pain was evaluated by McGill scores assessed by short-form of Mcgill pain questionnaire(SF-M PQ)and visual analogue scale(VAS)before(T0)and after 1(T1)and 2 weeks(T2)of transversus abdominis plane block, and 1(T3)and 8(T4)weeks after end of the treatment.Pain relief(PAR)was calculated by the formula: PAR=(VAS score before block--VAS score after block)/ VAS score before block × 100%.The morphine consumption and sleep quality were observed during the treatment and 1 week after treatment.Analgesic efficacy was graded 8 weeks after end of treatment.The effective rate and good response rate were calculated.Incidences of complications were recorded. Results There was no significant difference in the VAS score between the two groups before treatment(t=0.419, P>0.05), while VAS scores after treatment were lower in the observation group than in the control group(t=17.925, 19.662, 12.580 and 13.987, respectively, P 0.05). After treatment, the total scores of McGill were lower in the observation group than in the control group(t=18.612, 20.135, 13.213 and 12.356, respectively, P 0.05). While after treatment, the morphine consumptions were decreased in the observation group versus in the control group(t=22.341, 16.758, 17.827, 15.541 respectively, P<0.05). No punctures of abdominal cavity, chest cavity, internal organs or blood vessels by mistake occurred. Conclusions Ultrasound-guided transversus abdominis plane block is effective and has less adverse reactions in treating herpetic neuralgia located in anterior abdominal wall.

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.
