Abstract：
UNASSIGNED: The ultrasound-guided infraclavicular brachial plexus block by triple-point injection method was aimed at blocking the three individual cords in the infraclavicular region. Recently, a single-point injection method which does not require visualization of cords to produce nerve block has been introduced. This study compared the block onset time, performance time, patient\'s satisfaction, and complications between the ultrasound guided triple-point injection and single-point injection methods.
UNASSIGNED: This randomized controlled trial was conducted in a tertiary care hospital. Sixty patients were divided into two groups - Group S: 30 patients received single-point injection method of infraclavicular block. Group T: 30 patients received triple-point injection method of infraclavicular block. Drugs used were 0.5% ropivacaine with 8 mg dexamethasone.
UNASSIGNED: The sensory onset time was significantly longer in Group S (11.13 ±1.83 min) than Group T (6.20 ±1.19min). No statistically significant difference was found between the two groups regarding mean motor onset time. The composite sensorimotor onset time was similar between the groups. The mean time to perform the block was significantly lesser in Group S (1.35 ±0.38 min) when compared to group T (3.44 ±0.61min). The patient satisfaction score, conversion to general anesthesia and complications were not significant among the two groups.
UNASSIGNED: We concluded that single-point injection method had a shorter performance time and similar total onset time with less procedural complications compared with triple point injection method.

摘要：
■通过三点注射方法进行超声引导的锁骨下臂丛神经阻滞旨在阻滞锁骨下区域的三个单独的索。最近,已经引入了一种单点注射方法，该方法不需要可视化脊髓来产生神经阻滞。这项研究比较了阻滞开始时间，性能时间，患者的满意度，超声引导下三点注射和单点注射方法的并发症。
■这项随机对照试验是在三级保健医院进行的。将60例患者分为两组-S组：30例患者接受锁骨下阻滞单点注射法。T组：30例患者采用锁骨下阻滞三点注射法。使用的药物是0.5％罗哌卡因和8mg地塞米松。
■S组感觉起效时间(11.13±1.83min)明显长于T组(6.20±1.19min)。两组之间的平均运动起效时间无统计学差异。两组间的复合感觉运动起效时间相似。与T组（3.44±0.61分钟）相比，S组的平均阻滞时间（1.35±0.38分钟）明显较少。患者满意度评分,两组患者转换为全身麻醉和并发症均无统计学意义.
■我们得出的结论是，与三点注射法相比，单点注射法的表现时间更短，总起效时间相似，手术并发症更少。
