BACKGROUND:Neuroendocrine dysfunction after traumatic brain injury(TBI)has received increased attention due to its impact on the recovery of neural function.The purpose of this study is to investigate the incidence and risk factors of adrenocortical insufficiency(Al)after TBI to reveal independent predictors and build a prediction model of Al after TBI.METHODS:Enrolled patients were grouped into the Al and non-AI groups.Fourteen preset impact factors were recorded.Patients were regrouped according to each impact factor as a categorical variable.Univariate and multiple logistic regression analyses were performed to screen the related independent risk factors of Al after TBI and develop the predictive model.RESULTS:A total of 108 patients were recruited,of whom 34(31.5％)patients had Al.Nine factors(age,Glasgow Coma Scale[GCS]score on admission,mean arterial pressure[MAP],urinary volume,serum sodium level,cerebral hernia,frontal lobe contusion,diffuse axonal injury[DAI],and skull base fracture)were probably related to Al after TBI.Three factors(urinary volume[X4],serum sodium level[X5],and DAI[X8])were independent variables,based on which a prediction model was developed(logit P=-3.552+2.583X4+2.235X5+2.269X8).CONCLUSIONS:The incidence of Al after TBI is high.Factors such as age,GCS score,MAP,urinary volume,serum sodium level,cerebral hernia,frontal lobe contusion,DAI,and skull base fracture are probably related to Al after TBI.Urinary volume,serum sodium level,and DAI are the independent predictors of Al after TBI.
