Application of ultrasound-guided transversus abdominis plane block with methanesulfonic acid ropivacaine and intravenous propofol anesthesia in lower abdominal surgery and postoperative analgesia in children
Bibliographic record
Abstract
Objective To investigate the clinical application of ultrasound-guided transversus abdominis plane block (TAPB) combined with intravenous propofol in children with lower abdominal surgery and postoperative analgesia. Methods One hundred and twenty children underwent lower abdominal surgery in the Department of General Surgery and Urology departments of the Seventh People's Hospital of Hebei Province from July 2015 to April 2016, aged 2-5 years old, body mass index of 15-18 kg/m2 and ASA I, were randomly divided into TAPB/Pro group, Pro/RF group, and Sev/RF group, with 40 cases in each group. The patients were given ultrasound-guided TAPB combined with intravenous propofol anesthesia in TAPB/Pro group, intravenous propofol and remifentanil for total intravenous anesthesia in Pro/RF group, and compound intravenous and inhalational anesthesia with sevoflurane and remifentanil in Sev/RF group. All patients were given patient-controlled intravenous analgesia with fentanyl after the surgery. SBP, DBP, HR, MAP and SpO2 were compared among the three groups at the time of entering the operating room, skin incision, traction and awakening. The total dosage of propofol and fentanyl were counted in TAPB/Pro and Pro/RF groups. The awakening time and stay time in PACU were recorded. Children's Hospital of East Ontario Pain Score (CHEOPS) was recorded at 2, 4, 8 and 12 h after the operation and the pressing times of analgesia pump was compared after the operation. Results The final subjects was 110 cases. The levels of SBP, DBP, HR and MAP in TAPB/Pro group were lower than those in Pro/RF and Sev/RF groups (P<0.05). The dosage of propofol, the awakening time and stay time were lower than those in Pro/RF and Sev/RF groups. The CHEOPS and the pressing times of analgesia pump were lower in TAPB/Pro group at 2, 4, and 8 h after the operation than those in Pro/RF and Sev/RF groups (P<0.05). There was no significant difference for indexes mentioned above between the Pro/RF and Sev/RF groups at each time point. Conclusion The analgesic effect of ultrasound-guided transversus abdominis plane block with 0.316% methanesulfonic acid ropivacaine and intravenous propofol anaesthesia is good for lower abdominal surgery in children.

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.
