本研究为一项
前瞻性、双盲、随机对照试验，在接受单侧全膝关节置换术的50名对非甾体抗炎药副作用敏感的患者中进行。所有患者均接受椎管内麻醉、内收肌管阻滞和关节周围浸润。干预组的25名患者接受
SNB (0.125%布比卡因[20 ml]和地塞米松[5 mg])。
SNB组在第6、12和18小时的静息疼痛评分明显较低
:对照组为1(0–4.5)、3(0–5)和3(2–5)；SNB
组为0(0–0)、0(0–3)和1(0–3)；p值分别为0.012、0.021和0.010。6、12和18小时的运动疼痛评分也较低:对照组为3(0–5.5)、5(2.5–6.5)和7(4–9)；SNB组为0(0–1.5)、2(0–4)和3(2–5)；p值分别为0.019、0.005和0.001。两组运动功能无差异。此外，

Adding a low-concentration sciatic nerve
block to total knee arthroplasty in patients susceptible to the adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs): a randomized controlled trial
Background:
This study compared the effects of adductor canal blocks with those of a low concentration of popliteal-sciatic nerve block (SNB) and dexamethasone as an adjunctive technique for total knee arthroplasties (TKA)
in patients susceptible to the adverse effects of NSAIDs.
Methods:
A prospective, double-blinded, randomized controlled trial was performed in 50 patients susceptible to the adverse effects of NSAIDs undergoing unilateral TKAs. All patients received spinal anesthesia, adductor canal blocks, and periarticular infiltration. The 25 patients in the intervention group received SNB (0.125% bupivacaine [20 ml] and dexamethasone [5 mg]).
Results:
The SNB group significantly had lower median resting pain scores at 6, 12, and 18 h: the control group, 1 (0–4.5), 3 (0–5), and 3 (2–5); the intervention group, 0 (0–0), 0 (0–3), and 1 (0–3); p-values, 0.012, 0.021, and 0.010, respectively. Movement-evoked pain scores at 6, 12, and 18 h were also lower: control group, 3 (0–5.5), 5 (2.5–6.5), and 7 (4–9); intervention group, 0 (0–1.5), 2 (0–4), and 3 (2–5); p-values, 0.019, 0.005, and 0.001, respectively. There were no differences in motor function. Moreover, the mean morphine consumption 24 h was also reduced in the SNB group: control group, 3.80±2.48 mg; intervention group, 1.96±2 mg; p-value, 0.005.
Conclusion:
For patients susceptible to the adverse effects of NSAIDs, a low concentration of SNB and dexamethasone is an effective adjunctive technique for early postoperative pain control (especially on movement) following TKAs, without an increase in motor weakness.
