Assessment of QT interval and QT dispersion following stellate ganglion block using computerized measurements

Abstract

Right SGB induces increases of the QT interval, QTc interval, QTD, and QTcD, and left SGB induces decreases of the QT interval and QTc interval.

Use of Stellate Ganglion Block to Salvage an Ischemic Hand Caused by the Extravasation of Vasopressors

“…Reported major complications from stellate blocks are rare but include intravascular injection with cardiac and neurotoxicity, intrathecal injection, and pneumothorax. Right stellate ganglion blocks have been shown to increase the QT interval 14 and may cause a slight reduction in cardiac output. 15 Performing any nerve block in an unconscious patient should not be taken lightly because of the lack of explicit consent and the importance of patient feedback in helping detect a poorly positioned needle.…”

Effects of head-up tilt after stellate ganglion block on QT interval and QT dispersion

“…1 Left SGB induces a significant decrease of QT interval and QTc interval. 1 The postural change from supine to the head-up position also induces increases of QT interval and QTcD 3 and hemodynamic changes. 4 Increases of QT interval and QTD are associated with increased risks of arrhythmias and cardiovascular diseases.…”

“…However, SGB and head-up tilt after the block may synergistically exert an unfavorable influence on electrocardiographic findings or hemodynamic parameters. [1][2][3][4] Our previous study showed that right SGB induces signifi-cant increases of QT interval, rate-corrected QT (QTc) interval, QT dispersion (QTD), and rate-corrected QT dispersion (QTcD). 1 Left SGB induces a significant decrease of QT interval and QTc interval.…”
