Bupivacaine hydrochloride 0.5% (5 mg/mL) is commonly utilized for analgesia in brachial plexus blocks. We suggest that ultrasound-guided 0.25% (2.5 mg/mL) bupivacaine can be utilized for effective postoperative analgesia to reduce the effective dose. A total of 126 patients underwent ultrasound-guided brachial plexus blocks with 0.25% bupivacaine. The mean duration of analgesia was 21.95 (σ = 3.93) hours with no complications. Patients that received an infraclavicular block (22.56 σ = 4.02) had a significant increase in analgesia compared to supraclavicular blocks (21.09, σ = 3.69) (p = 0.04). These results suggest that further research is warranted for ultrasound-guided 0.25% bupivacaine in brachial plexus nerve blocks.
0.5%（5毫克/毫升）的盐酸布比卡因常用于臂丛神经阻滞镇痛。我们建议，超声引导下使用0.25%（2.5毫克/毫升）布比卡因可用于有效的术后镇痛，以降低有效剂量。共有126例患者接受了超声引导下0.25%布比卡因臂丛神经阻滞。平均镇痛时间为21.95（标准差=3.93）小时，无并发症。与锁骨上阻滞（21.09，标准差=3.69）相比，接受锁骨下阻滞（22.56，标准差=4.02）的患者镇痛时间显著延长（p=0.04）。这些结果表明，有必要对超声引导下0.25%布比卡因用于臂丛神经阻滞进行进一步研究。
