超声引导下环肱动脉神经阻滞在手外伤患者中的临床应用

Clinical study of ultrasound-guided nerve block around brachial artery in hand trauma patients

目的:观察在超声引导下环肱动脉神经阻滞技术用于手外伤患者的临床效果。方法:选择麻醉ASA I^I级行急诊手外伤手术病例60例,随机均分为超声引导下环肱动脉阻滞组(I组)和盲探阻滞组(I组)。两组患者均用1%利多卡因和0.375%罗哌卡因混合液进行神经阻滞。观察两组神经阻滞操作时间、起效时间、效果以及并发症的发生情况。结果:两组患者神经阻滞起效时间差异无统计学意义(P>0.05);I组神经阻滞操作时间较I组显著缩短,差异有统计学意义(P<0.05);两组患者在注药后15 min手部感觉神经支配及运动神经支配区域阻滞效果差异无统计学意义(P>0.05)。结论:在超声引导下进行环肱动脉神经阻滞,能够缩短麻醉操作时间,注射较少的局部麻醉药取得满意的阻滞效果,减少并发症,用于手外伤患者安全有效。

Objective： To explore the clinical effect of ultrasound-guided nerve block around brachial artery on the hand trauma patients. Methods： Sixty patients treated with hand trauma surgery were divided into two groups randomly, named the group Ⅰ （ultrasound-guided nerve block group） and the group Ⅱ （blind block group）. Mixture by lidocaine 1% and ropivacaine 0.375% as local anesthesia was used for nevre block in two groups. The nerve block operation time, the onset time of anesthesia, the effectireness of nerve block and the complication of the two groups were observed. Results： There was no statistically significant difference of the onset time and the anesthesia effectreness between two groups of patients （P〉0.05）. The operation time of group Ⅰ was obviously shorter than that of the group Ⅱ （P〈0.05）. The difference of anesthesia effect of hand sensory innervation and mo- tor innervation regional was no statistically significant. Conclusion： Ultrasound-guided nerve block around bra- chial artery on the hand trauma patients can shorten the anesthesia operation time, ensure the satistied anesthetic effect, and is effective and safe.
