研究目的:

本研究旨在通过“六阶段递进式培训”体系,提升渝东北地区基层医疗机构麻醉医生对超声引导神经阻滞技术的掌握与应用能力。主要评估该培训模式对医生技术熟练度、操作成功率、并发症率(目标<1%)及操作信心的影响。同时,评估技术推广后对患者术后疼痛评分(VAS)及平均住院日的影响,为基层麻醉技术规范化培训提供效果证据。  

Objectives of Study:

This study aims to enhance the proficiency and application of ultrasound-guided nerve block (UGNB) techniques among anesthesiologists in primary healthcare institutions in Northeast Chongqing through a "six-phase progressive training" system. It primarily evaluates the impact of this training model on physicians’ technical proficiency, procedural success rate, complication rate (target <1%), and operational confidence. Additionally, it assesses the effects on patient outcomes, including postoperative pain scores (VAS) and average length of hospital stay, to provide evidence for the effectiveness of standardized anesthesia training in primary care settings.
