Polarised light stellate ganglion irradiation (PLSGI) is a non-invasive and effective physiotherapy method for regulating the sympathetic nervous system. This study aims to investigate the effects of perioperative PLSGI on PTSD and pain-related outcomes in patients undergoing emergency surgery.<h4>Methods and analysis</h4>This multicentre, randomised, double-blind, controlled trial will include 510 adult patients scheduled for emergency trauma surgery. Patients will be randomly assigned in a 1:1 ratio, stratified by anaesthesia type (propofol general anaesthesia or other anaesthesia), to either the PLSGI group or the controlBMJ openEffect of perioperative polarised light stellate ganglion irradiation on postoperative stress disorder in emergency trauma patients: protocol for a randomised controlled trial.PMC12574353NSFC82171912NSFC81801332LKZ2023016NSFC82071903JSDW202231Li YGong CZhu YWang XHan DYu YWang LfalseEffect of perioperative polarised light stellate ganglion irradiation on postoperative stress disorder in emergency trauma patients: protocol for a randomised controlled trial.<h4>Background</h4>The hyperactivity of the sympathetic nervous system after a traumatic event contributes to the development of post-traumatic stress disorder (PTSD).
