脉冲传输时间的变化之间的关系和临床症状的存在后stallate神经节阻断(SGB)调查患者的疾病由交感神经系统。SGB用于这些疾病的治疗和诊断;然而,一个成功的目标标记不存在。因此,识别SGB后血流增加,决定脉冲渡越时间可以用来验证成功的小企业将是一个有用的资源。背景:客观标志成功的星状神经节块(SGB)并不存在。霍纳综合征,目前用于确定SGB的影响,有时是模糊的。摘要目的:探讨改变脉冲渡越时间(PTT) SGB之后,和PTT的评价效用SGB客观衡量成功。方法:8例(34 - 62岁)接受了SGB同情地介导的诊断或治疗上肢的疼痛。成功的SGB决心根据霍纳综合征的存在。心电描记法,无创血压测量和脉搏血氧仪是用于监控所有的病人。PTT测量使用数据保存在浏览器WinDaq波形。结果:PTT在基线测量,3分钟、5分钟和10分钟后注射局部麻醉。 At 3 min after SGB, the mean (± SD) PTT was 624.6±20.5 ms. At 5 min after injection, the mean PTT was 630.8±17.5 ms. Prolonged PTT at 5 min was found to return to the baseline value at 10 min (613.6±14.7 ms). According to the Friedman test, the differences from baseline values were significant (P=0.008).CONCLUSION: Measurement of PTT at 5 min after local anesthetic injection can help to objectively determine the success of SGB.
