Progress in monitoring indices for lumbar sympathetic ganglion block
Lumbar sympathetic ganglion block(LSGB)refers to the technique of using physical methods or chemical agents to act on the lumbar sympathetic ganglia or nerve chain to regulate neural conduction function.LSGB has been widely applied in the treatment of various neuropathic pain and vascular diseases.However,the timely and accurate assessment of block success still requires further study.This paper reviews the monitoring methods for successful lumbar sympathetic nerve block,with a focus on direct blood flow-related and non-blood flow-related monitoring indicators,aiming to provide a reference for clinical selection.
