Efficacy and safety of ultrasound-guided stellate ganglion block: Comparison of through anterior scalenus muscle and through internal jugular vein / 中国医学影像技术

ABSTRACT

Objective: To compare the efficacy and safety of ultrasound-guided stellate ganglion block (UGSGB) through anterior scalenus muscle (ASM) and through internal jugular vein (IJV). Methods: Totally 144 patients with cervicogenic headache were distributed into 2 groups randomly. USSGB was performed through ASM (ASM group, n=72) or through IJV (IJV group, n=72), respectively. The ratio of successful blocks, the appearing time of Honer syndrome and the ratio of adverse reaction were compared between two groups. Results: The successful block ratio was 97.22% (70/72) of ASM group and 98.61%(71/72) of IJV group, while Honer syndrome appearing times was (2.18±0.96)min and (1.96±0.87)min after operation, respectively. There was no significant difference between 2 groups (both P>0.05). The adverse reaction ratio was 19.44%(14/72) of SCM group and 4.17%(3/72) of IJV group (P=0.01). Conclusion: USSGB through ASM approach and USSGB through IJV approach are both safe and efficient. IJV approach has less adverse reaction than SCM approach.
