The aim of this study is to compare the efficacy of stellate ganglion block, performed by ultrasound guided technique and blind technique, and ultrasound guided T2 intercostal nerve block.
In the present study, we evaluated the changes in upper arm skin temperature, and the development of Horner syndrome after stellate ganglion block (blind technique and ultrasound guided technique) and ultrasound guided T2 intercostal nerve block in 12, 11 and 10 patients scheduled for each block. Stellate ganglion blocks (blind technique) were performed via an anterior paratracheal approach at C6 using 1% mepivacaine 5 ml. Ultrasound guided stellate ganglion blocks were performed using 8-5 MHz, curved array transducer, and 1% mepivacaine 5 ml is injected to the longus colli muscle at C6 by the out of plane technique. Ultrasound guided intercostal nerve blocks were performed using 13-6 MHz, linear array transducer, and 0.75% ropivacaine 5 ml at T2. Patients were examined before and after the procedure.
There were no significant differences in the increase of skin temperature and the development of Horner syndrome between the groups.
Compared to stellate ganglion block (blind technique), ultrasound guided stellate ganglion block and T2 ultrasound-guided intercostal nerve block provided a similar efficacy.
本研究旨在比较超声引导技术和盲法技术进行的星状神经节阻滞以及超声引导下T2肋间神经阻滞的疗效。
在本研究中，我们评估了12例、11例和10例分别接受每种阻滞的患者在星状神经节阻滞（盲法技术和超声引导技术）以及超声引导下T2肋间神经阻滞后上臂皮肤温度的变化和霍纳综合征的发生情况。星状神经节阻滞（盲法技术）通过在C6水平经气管旁前路进行，使用1%甲哌卡因5毫升。超声引导下的星状神经节阻滞使用8-5MHz的弯形阵列探头进行，通过平面外技术将1%甲哌卡因5毫升注入C6水平的颈长肌。超声引导下的肋间神经阻滞使用13-6MHz的线性阵列探头进行，在T2水平注入0.75%罗哌卡因5毫升。在操作前后对患者进行检查。
各组之间在皮肤温度升高和霍纳综合征的发生方面没有显著差异。
与星状神经节阻滞（盲法技术）相比，超声引导下的星状神经节阻滞和T2超声引导下的肋间神经阻滞疗效相似。
