Predictive Value Of Various Shock Indexes In The Prognosis Of Patients With Emergency Trauma

Objective:To investigate the value of various shock indexes in assessing the prognosis of trauma patients,and provide a certain guiding significance for clinical practice.Methods:The clinical data of trauma patients were collected in the Department of Emergency from January 2016 to December 2017.（1）The 28-day prognosis was used as the end point,and the patients were divided into the survival group and the death group.The clinical parameters such as the shock index of the two groups were compared,and the relationship between the above indexes and prognosis was analyzed.（2）Patients were divided into<9,9-15,>15 groups according to r SIG（Reverse shock index multiplied by Glasgow Coma Scale score）,and（27）0.15、0.15-0.30、（29）0.30 according to r SIG/A（r SIG divided by age）,then the difference in mortality between the three groups was compared.Results:A total of 1439 patients were enrolled,including 1062（73.8%）males and377（26.2%）females.The shock index,modified shock index,adjusted shock index,age shock index in the survival group were significantly smaller than the death group[（0.6±0.2）vs.（1.1±0.7）、（0.9±0.2）vs.（1.6±1.0）、（0.6±0.2）vs.（1.1±0.7）、（31.7±12.6）vs.（57.2±42.5）,P（27）0.05];r SIG and r SIG/A were significantly greater than death group[（22.5±8.6）vs.（9.3±7.6）,（0.5±0.3）vs.（0.2±0.1）,P（27）0.001].The ability of r SIG and r SIG/A to judge the mortality of trauma patients is better than other shock indexes.The mortality rate gradually decreased with increasing r SIG or increasing r SIG/A(P_trend（27）0.001).Conclusion:various shock indexes can better assess the severity and prognosis of trauma patients,and it has certain reference for clinical practice.However,r SIG and r SIG/A are more accurate in assessing the severity and prognosis of casualties while maintaining a simple and fast feature.
