Summary

Objective: This study aimed to evaluate the clinical value of a multidisciplinary collaboration (MDC)-based perioperative pain management model. Methods: A prospective, randomized controlled trial was conducted involving 126 patients who underwent anorectal surgery between July 2022 and December 2023. Participants were randomly assigned (1:1) using a computer-generated sequence to either the control group (n = 63), which received standard nursing care, or the observation group (n = 63), which received nursing care based on the MDC model integrating surgery, anesthesiology, nursing, psychology, and pharmacy disciplines.

BEHAVIORAL

Standard Nursing Care Protocol

The control group received standard perioperative nursing care in accordance with the Chinese Consensus and Clinical Guidelines for Enhanced Recovery After Surgery (2021 edition) and the Expert Consensus on Perioperative Nursing of Anorectal Diseases (2022 edition). Preoperative fasting included a 6-hour restriction on solid food and a 2-hour restriction on clear liquids. At 8:00 p.m. on the night before surgery, patients were instructed to orally ingest 500 mL of 10% glucose solution to supplement energy reserves. Fifteen minutes of structured health education was delivered preoperatively by the assigned nurse using 3D animations to explain the surgical process. Intraoperatively, an inflatable warming blanket was used to maintain the core temperature at 38°C, and all infusion fluids were pre-warmed to 37°C. For infection prophylaxis, 30 minutes before incision, patients received intravenous cefazolin (1 g for body mass index \[BMI\] \< 25 kg/m²; 2 g for BMI ≥ 25 kg/m²).

BEHAVIORAL

MDC-based Pain Management

In accordance with the IASP Guidelines for Multidisciplinary Postoperative Pain Management (2023) and the Expert Consensus on Multidisciplinary Collaboration for Pain Management in China, a three-tier MDC framework was established;Surgeons were responsible for optimizing surgical procedures (e.g., using the tissue selecting technique for stapled hemorrhoidectomy) and administering a local injection of 5 mL 0.25% ropivacaine around the wound margin at the end of surgery. Anesthesiologists performed preoperative ASA physical status classification, monitored intraoperative vital signs, and configured postoperative patient-controlled analgesia (PCA) with sufentanil at 0.02 μg/kg/h.Compound Methylene Blue Nerve Block: A solution was prepared by mixing 2 mL of 1% methylene blue, 10 mL of 0.75% ropivacaine, and 8 mL of normal saline, yielding final concentrations of 0.02% methylene blue and 0.25% ropivacaine.
