简介：摘要目的探讨通过超声技术3%的罗哌卡因在锁骨骨折臂丛-颈浅丛麻醉中的临床应用价值。方法选择120例择期行锁骨骨折手术患者,年龄18-70岁,ASAⅠ-Ⅲ级，随机分为传统药物组（n=60例）和超声药物组（n=60例）。传统药物组通过手法盲探定位臂丛肌间沟及颈浅丛应用0.5%的罗哌卡因25ml完成阻滞，超声药物组通过B超实时引导定位臂丛肌间沟及颈浅丛应用0.3%的罗派卡因完成阻滞。结果超声药物组穿刺时间明显短于传统药物组（P<0.05)穿刺次数少于传统药物组（P<0.05);超声药物组穿刺后并发症明显低于传统药物组（P<0.01)；超声药物组麻醉效果优于传统药物组，药物浓度低于传统药物组。结论
