研究目的:

全膝关节置换术(TKA)后约有60%的患者会出现中至重度疼痛,尤以术后48至72小时最为剧烈。其中相当一部分为老年患者,由于其身体功能减退及疼痛耐受性较差,若在围术期未能给予有效的镇痛干预,极易发展为慢性疼痛。同时,术后疼痛常常阻碍患者进行早期康复训练,增加发生深静脉血栓、肺部感染及心血管事件等并发症的风险,从而延长住院时间,影响术后恢复质量。我们在前期临床麻醉实践中观察到,在超声引导下L5-S1间隙行腰麻时,其部分麻醉平面的持续时间较L3-L4间隙更长,平面消退更慢,镇痛作用更为持久。基于此,我们推测麻醉平面持续时间的延长可能与穿刺节段较低(L5-S1)有关。本研究旨在比较超声引导下L5-S1间隙与L3-L4间隙腰麻在膝关节置换术中的麻醉维持时间及麻醉平面消退时间,并进一步探讨其对术后镇痛效果的影响,为优化术后镇痛策略提供理论依据。  

Objectives of Study:

Approximately 60% of patients undergoing total knee arthroplasty (TKA) experience moderate to severe postoperative pain, with the most intense pain typically occurring within 48 to 72 hours after surgery. A significant proportion of these patients are elderly, who generally have diminished physiological function and lower pain tolerance. Inadequate perioperative pain management in this population markedly increases the risk of progression to chronic pain. Moreover, postoperative pain often impedes early rehabilitation exercises and may trigger various complications, including deep vein thrombosis, pulmonary infections, and cardiovascular events, thereby prolonging hospital stay and adversely affecting postoperative recovery.Our preliminary clinical anesthesia observations indicate that spinal anesthesia administered at the L5-S1 interspace under ultrasound guidance results in a longer duration of anesthetic plane maintenance, slower regression, and prolonged analgesic effect compared to the L3-L4 interspace. We hypothesize that the prolonged duration of anesthesia may be associated with the lower puncture level (L5-S1).This study aims to compare the anesthetic maintenance time and regression of sensory block between spinal anesthesia at the L5-S1 and L3-L4 interspaces under ultrasound guidance in TKA patients, and to investigate the impact of these differences on postoperative analgesia. The findings are expected to provide theoretical support for optimizing postoperative pain management strategies.

随机方法(请说明由何人用什么方法产生随机序列):

使用RandA1.0随机化软件,由第三方研究协调员在临床试验开始前生成随机分组序列。采用区组随机(每组4人一组),按照1:1比例将患者随机分配至L5-S1组或L3-4组。

Randomization Procedure (please state who generates the random number sequence and by what method):

The randomization sequence was generated by a third-party research coordinator using the RandA1.0 randomization software prior to the start of the clinical trial. Block randomization was applied, with 4 participants per block, and patients were assigned at a 1:1 ratio to either the L5-S1 group or the L3-4 group.

盲法:

采用单盲设计,患者和随访评估医生对分组情况不知情。执行麻醉操作的医生知晓分组,但不参与后续观察和数据收集,以减少观察者偏倚。

Blinding:

A single-blind design was adopted. Participants and outcome assessors were blinded to group assignments. The anesthesiologists who performed the procedures were aware of the group allocation but were not involved in postoperative assessment or data collection to minimize observer bias.
