简介：目的研究北京市听障儿童智力发育的特点，比较听障儿童与健听儿童智力发育的差别，为北京市听障儿童康复工作提供理论依据。方法采用希一内学习能力测验的健听常模对56名听障儿童和56名相同年龄的健听儿童的智力进行测验。结果3～7岁听障儿童的比率智商是94．99±14．27，56名健听儿童的比率智商是96．49±12．98，两者的差别没有统计学意义；4岁之前二者的智力水平发展一致，随着年龄的增加，二者的差距增大，差别无统计学意义。与健听儿童相比，听障儿童的手眼协调、空间知觉、视觉记忆和抽象思维发展较好，而色彩记忆和分析综合能力发展滞后。结论北京市听障儿童智力发育良好，已接近健听儿童的水平，社会和家庭应继续关注听障儿童的早期干预和心理健康，以期达到全面康复的目的。

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
