研究目的: |
膝关节置换术术后早期活动在患者护理中尤为重要,其中早期活动可能带来的好处,包括减少深静脉血栓和肺栓塞等并发症,对肌肉骨骼健康的积极影响,有助于预防术后肌肉萎缩和关节僵硬。因此寻找能够实现患者早期活动并确保有效围术期疼痛管理的区域麻醉技术至关重要。多模式镇痛理念下应谨慎避免局部麻醉剂全身毒性,尤其是老年和虚弱患者。相关研究应特别关注区域麻醉技术的浓度和剂量。尽管已有报道指出,10mlLB收肌管阻滞能获得不错的镇痛效果,但超声引导下收肌管阻滞的最小有效体积(MEV)仍不清楚。确定MEV对于防止不必要的高剂量给药至关重要。此外,当对同一患者进行多处阻滞时,了解MEV可以在确保治疗成功的同时不牺牲其安全性。因此,本研究为了确定超声引导下布比卡因脂质体用于收肌管阻滞对老年患者全膝关节置换术术后完善镇痛的同时避免使用过多的局麻药,从而确定最低有效体积(minimum effective volume, MEV),具有重要的临床意义。本研究采用有偏硬币设计(biased coin design, BCD)序贯法确定超声引导下0.665%布比卡因脂质体注射液用于收肌管阻滞对老年患者全膝关节置换术术后镇痛的90%MEV(MEV90)。 |

Objectives of Study: |
Early mobilization after total knee arthroplasty is particularly important in patient care. Its benefits include reducing complications such as deep vein thrombosis and pulmonary embolism, exerting positive effects on musculoskeletal health, and helping prevent postoperative muscle atrophy and joint stiffness. Therefore, it is critical to identify regional anesthesia techniques that enable early patient mobilization and ensure effective perioperative pain management. Under the concept of multimodal analgesia, systemic toxicity caused by local anesthetics should be carefully avoided, especially in elderly and frail patients. Relevant studies need to pay special attention to the concentration and dosage of regional anesthetic techniques. Although it has been reported that adductor canal block with 10 mL of local anesthetic can achieve favorable analgesic effects, the minimum effective volume (MEV) of ultrasound-guided adductor canal block remains unclear. Determining the MEV is essential to prevent unnecessary high-dose administration. In addition, when multiple nerve blocks are performed on the same patient, knowledge of the MEV helps guarantee therapeutic efficacy without compromising safety. Accordingly, this study aims to determine the minimum effective volume (MEV) of liposomal bupivacaine for ultrasound-guided adductor canal block in elderly patients undergoing total knee arthroplasty. This volume can provide adequate postoperative analgesia while avoiding excessive use of local anesthetics, which is of great clinical significance. A biased coin design (BCD) sequential method was adopted in this study to determine the 90% minimum effective volume (MEV90) of 0.665% liposomal bupivacaine injection for ultrasound-guided adductor canal block in elderly patients for postoperative analgesia after total knee arthroplasty. |
