围手术期分层多模式护理干预对全膝关节置换术后疼痛的疗效分析

Analysis of the Effectiveness of Layered Multimodal Nursing Interventions on Pain after Total Knee Replacement Surgery

摘要: 目的：系统整合近5年国内外高质量随机对照试验(RCT)、网状Meta分析、临床指南与队列研究，明确全膝关节置换术(Total Knee Arthroplasty, TKA)围手术期急性、慢性术后疼痛独立危险因素，构建术前风险分层–术中麻醉协同–术后药物 + 非药物一体化疼痛护理体系，量化评价各类护理措施对术后VAS疼痛评分、阿片类药物消耗量、关节活动度、并发症、住院周期及远期慢性疼痛发生率的改善效果，为关节外科标准化疼痛护理路径提供高级别循证依据。方法：检索PubMed、Cochrane Library、Web of Science、CNKI、万方、维普数据库，检索时限2021年1月~2026年5月；纳入TKA围手术期疼痛护理相关系统评价、大样本RCT、前瞻性队列、国内/国际权威指南；采用AGREE II、AMSTAR 2、Cochrane偏倚风险工具完成文献质量评价，GRADE分级证据强度，采用描述性整合对比单一护理、分层多模式联合护理的临床疗效。结果：传统同质化常规护理下，TKA术后12 h静息VAS均值4.7~5.2分、活动VAS 6.3~7.1分，48 h阿片类药物总消耗32.4~41.8 mg，术后12个月慢性持续性疼痛发生率22.7%~31.5%；女性、术前中重度慢性疼痛、焦虑抑郁、中枢敏化、双侧TKA、全麻、高炎症水平为高危疼痛人群。基于循证构建的分层多模式围手术期护理干预可使术后12 h静息VAS降至2.1~2.8分、活动VAS降至3.2~3.9分，48 h阿片消耗量下降58.2%，术后72 h疼痛补救给药率降低67.4%，膝关节屈曲活动度术后24 h提升18˚、48 h提升26˚，平均住院日缩短1.2~1.8 d，术后1年慢性疼痛发生率降至7.3%~11.6%，患者疼痛满意度提升27.5%，且无镇痛相关不良反应增加。结论：以风险分层为核心的围手术期多维度一体化护理可全方位阻断TKA疼痛发生通路，降低急性疼痛强度、减少阿片暴露、加速关节功能康复，并显著降低远期慢性疼痛发生风险，契合骨科ERAS发展要求，可在关节外科转化为标准化护理SOP推广。

Abstract: Objective: To systematically integrate high-quality randomized controlled trials (RCTs), network meta-analyses, clinical guidelines, and cohort studies from the past five years, both domestic and international, to identify independent risk factors for acute and chronic postoperative pain around total knee arthroplasty (TKA). The goal is to build a comprehensive pain management system that combines preoperative risk stratification, intraoperative anesthetic coordination, and postoperative pharmacological and non-pharmacological interventions. This study also aims to quantify the effects of various nursing measures on postoperative VAS pain scores, opioid consumption, joint mobility, complications, length of hospital stay, and long-term chronic pain incidence, providing high-level evidence for standardized pain care pathways in orthopedic surgery. Methods: We searched PubMed, Cochrane Library, Web of Science, CNKI, Wanfang, and VIP databases from January 2021 to May 2026. Included were systematic reviews, large-sample RCTs, prospective cohort studies, and authoritative domestic and international guidelines related to TKA perioperative pain management. Literature quality was assessed using AGREE II, AMSTAR 2, and the Cochrane risk of bias tools; evidence strength was graded using GRADE. Descriptive integration compared the clinical efficacy of single nursing interventions with stratified multimodal integrated care. Results: Under traditional homogeneous routine care, the mean resting VAS scores 12 hours post-TKA were 4.7~5.2, and active VAS scores were 6.3~7.1. Total opioid consumption at 48 hours was 32.4~41.8 mg, and the 12-month persistent postoperative pain incidence was 22.7%~31.5%. High-risk pain groups included women, those with moderate-to-severe preoperative chronic pain, anxiety or depression, central sensitization, bilateral TKA, general anesthesia, and high inflammatory levels. Evidence-based stratified multimodal perioperative nursing interventions reduced 12-hour resting VAS to 2.1~2.8 and active VAS to 3.2~3.9, decreased 48-hour opioid consumption by 58.2%, reduced 72-hour pain rescue medication rates by 67.4%, increased knee flexion by 18˚ at 24 hours and 26˚ at 48 hours postoperatively, shortened average hospital stays by 1.2~1.8 days, lowered 1-year chronic pain incidence to 7.3%~11.6%, and improved patient pain satisfaction by 27.5%, without increasing analgesia-related adverse effects. Conclusion: Multidimensional perioperative care centered on risk stratification can comprehensively block the pain pathways after TKA, reduce acute pain intensity, minimize opioid exposure, accelerate joint functional recovery, and significantly lower the risk of long-term chronic pain. This approach aligns with the ERAS principles in orthopedics and can be translated into standardized nursing SOPs in joint surgery.
