简要总结
Study Aim: This trial evaluates if a novel non-invasive, AI-assisted simulation training improves ultrasound-guided needle visualization skills in anesthesia residents.
Design: Trainees were randomized into two groups:
Intervention: AI-based, non-invasive simulated needle puncture training. Control: Conventional ultrasound teaching. Key Outcomes: The primary outcome is objective needle tip visibility. Secondary outcomes include anatomical identification, correct view acquisition, operator confidence, and overall scanning performance.
Assessment: Outcomes are measured via blinded expert evaluation and theoretical tests.
The goal of this randomized controlled clinical trial is to determine whether an ultrasound-guided non-invasive simulated needle puncture training technique can improve ultrasound-guided needle visualization skills in anesthesiology residents undergoing standardized residency training. The study is conducted in anesthesiology residents enrolled in a standardized residency training program.
The main questions it aims to answer are:
- Does non-invasive simulated needle puncture training improve objective needle tip visibility during ultrasound-guided peripheral nerve block procedures?
- Does this training method improve anatomical structure identification, acquisition of correct block views, operator confidence, and overall scanning performance compared with conventional ultrasound teaching? Researchers will compare a non-invasive simulated needle puncture training group with a conventional ultrasound teaching group to see if the simulated training technique leads to superior needle visualization and procedural performance.
Participants will:
Receive standardized theoretical instruction on ultrasound- guided peripheral nerve blocks; Be randomly assigned to either non-invasive simulated needle puncture training using an artificial intelligence-assisted system or conventional ultrasound scanning training; Perform ultrasound scanning and simulated or conventional practice on healthy volunteers; Undergo theoretical examinations and blinded expert assessments of ultrasound scanning performance and needle visualization outcomes.
详细描述
- Teaching Implementation Prior to training, a questionnaire survey was used to collect basic information from the trainees. The course content was developed based on the following textbooks: Clinical Anesthesiology (4th Edition) edited by Guo Qulian and Yao Shanglong and published by People's Medical Publishing House; Modern Anesthesiology (4th Edition) edited by Deng Xiaoming et al. and published by People's Medical Publishing House; and Ultrasound-Guided Nerve Block Techniques edited by Wang Aizhong et al. and published by Shanghai Jiao Tong University Press.
All participants initially attended a two-hour instructional course led by two teaching instructors. The course covered the techniques of interscalene brachial plexus, rectus sheath, adductor canal, and sciatic nerve blocks at the popliteal level. The content was based on the recent consensus project for basic ultrasound-guided blocks (Plan A) led by the British Association of Regional Anaesthesia, which defined strongly recommended structures for targeted scanning and block views. The specific structures included:
Interscalene Brachial Plexus Block: Anterior scalene muscle; C5 nerve root; C6 nerve root; Middle scalene muscle.
Rectus Sheath Block: Peritoneum; Rectus abdominis muscle; Anterior layer of the rectus sheath; Posterior layer of the rectus sheath.
Adductor Canal Block: Femoral artery; Saphenous nerve; Sartorius muscle. Sciatic Nerve Block at the Popliteal Level: Common peroneal nerve; Tibial nerve. An additional structure, the popliteal artery, was also included in the block view for the popliteal sciatic nerve block.

结局指标
主要结局
Percentage of needle tip visibility
时间窗: After two weeks of training, followed by one week of clinical rotation
For each procedure, investigators measured the absolute time during which the needle tip was visible on ultrasound (visible time) and calculated the percentage of needle tip visibility for each procedure (visible time / total procedure time × 100%), which was defined as objective needle tip visibility. The primary outcome measure of the study was the percentage of needle tip visibility.
