To determine if the infraclavicular brachial plexus block can be applied with lower volume of local anesthetic.
Randomised, double-blinded clinical trial.
60 patients aged 5-15years with ASA I-II who underwent emergent or elective arm, forearm or hand operations were included in the study.
Patients were divided into two groups randomly; standard volume local anesthetic administered group (Group S, n=30) and low volume anesthetic administered group (Group L, n=30).
Postoperative pain scores, sensory and motor block durations were noted.
Pain scores (Wong-Baker Face Scale) were evaluated and the results were detected to be similar at all times (30min, 1, 2, 4, 8, 12, 24h). Durations of motor block were 168(±16) minutes and 268(±15) minutes in Group L and Group S respectively and the difference was statistically significant (p<0.001). Durations of sensory block were 385(±26) and 402(±39) in Group L and Group S respectively and no statistically significant difference was detected (p=0.064).
Similar block success, postoperative sensory block durations and pain scores could be obtained during infraclavicular brachial plexus in pediatric patients with lower local anesthetic volumes.
确定锁骨下臂丛神经阻滞是否可以使用较低容量的局部麻醉剂。
随机、双盲临床试验。
60 名年龄在 5-15 岁、ASA I-II 级的患者，行上肢、前臂或手部急诊或择期手术。
患者随机分为两组；标准容量局部麻醉给药组（S 组，n=30）和低容量麻醉给药组（L 组，n=30）。
记录术后疼痛评分、感觉和运动阻滞持续时间。
评估疼痛评分（Wong-Baker 面部量表），结果在所有时间点均相似（30min、1、2、4、8、12、24h）。运动阻滞持续时间分别为 L 组 168(±16)分钟和 S 组 268(±15)分钟，差异有统计学意义（p<0.001）。感觉阻滞持续时间分别为 L 组 385(±26)分钟和 S 组 402(±39)分钟，差异无统计学意义（p=0.064）。
在小儿锁骨下臂丛神经阻滞中，使用较低容量的局部麻醉剂可获得相似的阻滞成功率、术后感觉阻滞持续时间和疼痛评分。
