摘要
目的观察超声引导下较低容量左布比卡因腋路臂丛神经阻滞的术后镇痛效果。方法将ASAⅠ~Ⅲ级的60例患者随机分成两组,即超声引导下神经阻滞组和全身麻醉组,每组各30例。阻滞局麻药使用0.25%左布比卡因,在超声引导定位下,分别阻滞正中、尺、桡以及肌皮神经,总量20mL。疼痛评分采用视觉模拟评分（VAS评分）,观察术后1、2、4、12、24h的疼痛情况。结果与全身麻醉组比较,超声引导下神经阻滞组患者术后1、2、4h均获得较低的VAS评分（均为P〈0.001）。结论超声引导下使用20mL的0.25%左布比卡因行腋路臂丛神经阻滞,术后镇痛效果优于全身麻醉。
Objective To observe the efficacy of ultrasound-guided axillary brachial plexus block with low volum of levobupivacaine for postoperative analgesia in patients undergoing upper extremity.Methods Sixty ASA Ⅰ-Ⅲ patients undergoing upper extremity were randomly divided into two groups（n=30each）：ultrasound-guided nerve block group and general anesthesia group.Under ultrasound-guided location,a bolus of 0.25%levobupivacaine 20mL was injected to ulnar nerve,radial nerve,median nerve and musculocutaneous nerve respectively and visual analogue scale（VAS）scores were evaluated at 1,2,4,12and 24hr after surgery.Results The efficacy of postoperative analgesia in ultrasound-guided nerve block group had significantly lower VAS score within 4hcompared with that in general anesthesia group.Conclusion The efficacy of postoperative analgesia in ultrasound-guided axillary brachial plexus block has an advantage over that in general anesthesia.
