随着日间手术在国内外的广泛应用，如何对日间手术患者实施有效的镇痛措施成为临床研究的热点。快速康复外科(ERAS)是以患者为中心，通过一系列具有循证依据的改良措施，从而减少创伤应激、加速患者康复的方法。充分镇痛作为ERAS的关键部分，可改善患者疼痛程度，降低疼痛评分，有利于患者早日活动，发挥最优的镇痛效果。基于此，笔者对日间手术患者术后镇痛策略及充分镇痛在ERAS发展中的重要作用进行述评。“,”With the widespread application of ambulatory surgery at home and abroad, how to implement effective analgesic measures for patients undergoing ambulatory surgery has become a hot spot in clinical research. Enhanced recovery after surgery (ERAS) is a patient-centered method, which can reduce the stress of trauma and accelerate the recovery of patients through a series of evidence-based improvement measures. As a key part of ERAS, adequate analgesia can improve the degree of pain and reduce the pain score, which is conducive to the early activity of patients and the best analgesic effect. Based on this, this article reviews postoperative analgesia strategies for patients undergoing ambulatory surgery and the important role of adequate analgesia in the development of ERAS.
