Efficacy and safety of stellate ganglion block for postoperative pain management: a systematic review and meta-analysis of randomized controlled trials.

Stellate ganglion block may help alleviate early pain (6, 12, and 24 h) postoperatively, It also shortens hospital and the ICU stays and reduces the incidence of nausea and vomiting but increases the incidence of upper eyelid ptosis.

Analysis showed no significant group-to-group differences in other indicators.

Given the limitations of the included studies, further high-quality, large-sample randomized controlled trials are needed to confirm and expand upon the efficacy and safety of stellate ganglion block.
