研究目的:

主要目的:采用Dixon等比序贯法确定布比卡因脂质体在老年全髋关节置换术患者行S-FICB中的半数有效浓度(EC50)及95%置信区间。 次要目的:评估不同浓度布比卡因脂质体的镇痛效果、安全性及术后恢复质量。  

Objectives of Study:

Main objective: The Dixon up-and-down sequential method was used to determine the median effective concentration (EC50) and 95% confidence interval of liposomal bupivacaine in elderly patients undergoing total hip arthroplasty with S-FICB. Secondary objective: To evaluate the analgesic effect, safety, and quality of postoperative recovery of liposomal bupivacaine at different concentrations.

Sample size:

干预措施:

干预措施名称:布比卡因脂质体髂筋膜间隙阻滞(S-FICB) 操作方法:在全麻诱导后实施超声引导S-FICB,采用40 mL固定体积。初始浓度0.040%,若上一例成功,下一例浓度降低2%;若失败则升高2%。出现7个“成功–失败”交替后终止试验。阻滞成功定义:术后24 h静息NRS≤2分、活动NRS≤3分、PCIA按压≤2次且无补救镇痛。

干预措施代码:

Intervention:

Intervention name: Liposomal bupivacaine supra-inguinal fascia iliaca compartment block (S-FICB) Method: Ultrasound-guided S-FICB was performed after general anesthesia induction using a fixed volume of 40 mL. The initial concentration was 0.040%. If successful in the previous case, the concentration was reduced by 2% in the next case; if failed, it was increased by 2%. The trial was terminated after 7 alternating "success–failure" outcomes. Block success was defined as a resting NRS ≤2, movement NRS ≤3, ≤2 PCIA presses, and no rescue analgesia within 24 hours postoperatively.
