Ultrasound guided injections of botulinum toxin type A into stellate ganglion to treat insomnia.

ABSTRACT: The aim of the study was to investigate the curative effect of botulinum toxin type A (BTX-A) injection into stellate ganglion under ultrasound guidance in patients suffering from insomnia. From October 2015 to April 2016, 48 patients suffering from insomnia were enrolled in this study. Patients were divided into 2 groups using a random digital grouping method: i) Control group (24 cases), and ii) treatment group (24 cases). Patients in the control group received 1 mg oral estazolam 30 min before sleep every night, while patients in the treatment group received BTX-A injection in bilateral stellate ganglions under ultrasound guidance. Curative effect evaluation was carried out after treatment. The international Pittsburgh Sleep Quality Index (PSQI) and polysomnogram (PSG) were evaluated in the two groups before and after treatment. The total effective rate was obviously higher in the treatment group. The PSQI score and the results of the PSG indicated that the insomnia situation improved in both groups. However, compared with the control group, the treatment group had a more significant improvement. In conclusion, BTX-A injection in stellate ganglion was a relatively easy and effective way to treat insomnia without any notable adverse reactions.
