Objective To explore the correlation of serum estradiol, testosteron and their ratio to the injury severity score (ISS) and Glasgow coma score (GCS) in patients with multiple traumatic injuries. Methods The serum levels of estradiol and testosteron were determined by radioimmunoassay double antibody precipitation method in 95 patients with multiple traumatic injuries within 24 h after trauma. The patients were grouped according to the ISS or GCS (in cases with craniocerebral injury) for comparison of the serum estradiol and testosterone levels with those in 15 normal individuals. Results In the acute stage of multiple trauma, a distinct declination of testosterone and a marked increment of estradiol were observed, and the changes were closely related to the severity of the trauma .The serum levels of estradiol and testosteron and their ratio differed significantly between patients with severe trauma (ISS>25) and the other groups (P<0.01), and also between patients with craniocerebral injury (with GCS of 3-5 or 5-8) and the other groups (P<0.01). Conclusion Serum estradiol and testosteron levels and their ratio are correlated to the severity of trauma and craniocerebral injuries, and may serve as indicators for evaluating the trauma severity and prognosis of the traumatic patients.%目的 研究多发创伤病人早期血清性激素睾酮、雌二醇变化与创伤严重度评分及格拉斯哥昏迷评分的关系,探讨创伤后两者及两者比值变化的意义.方法 急诊就诊的男性多发创伤患者95例,就诊时间均在伤后24 h 内,即时采集血样.采用放射免疫双抗体沉淀法测定病人早期血清中睾酮、雌二醇含量.按照ISS评分予以分组,其中合并颅脑损伤病人按GCS评分分组.并与15例上E常对照组比较,同时各分组间比较睾酮、雌二醇含量以及雌二醇/睾酮变化.结果 多发创伤病人早期.创伤越重,睾酮值降低越明显.雌二醇值升高.严重创伤组(ISS>25分)睾酮、雌二醇、雌二醇/睾酮值与其他组间对比有显著差异(P<0.01).合并颅脑损伤组按GCS评分分组:5≥GCS≥3组、8≥GCS>5组与对照组比较有显著性差异(P<0.01).结论 血清性激素睾酮、雌二醇水平的改变以及雌二醇/睾酮的改变与严重创伤、颅脑损伤的严重程度相关.可作为判断伤情、观察预后的参考指标.
