创伤患者离子钙的变化及临床意义

Changes and clinical significance of ionized calcium in trauma patients

目的观察创伤患者离子钙水平的变化及临床意义。方法 ICU的创伤患者94例,在入院时即行离子钙测定及创伤严重度评分(ISS评分),并取入院24h内最差的生理参数及实验室检查结果进行APACHEⅡ评分,按ISS分值、APACHEⅡ分值及预后分组。结果离子钙水平随着ISS、APACHEⅡ分值的增高而降低(P<0.01)。死亡组离子钙水平明显低于存活组,ISS及APACHEⅡ评分显著高于存活组(P<0.01)。结论创伤患者早期离子钙水平检测对临床评估创伤患者严重程度及预后有一定的意义。

Objective To observe the changes and clinical significance of ionized calcium in patients with trauma in early stage.Methods Serum levels of ionized calcium were measured at the time of entering ICU and the time of getting the worst reports of physical and laboratory examinations within 24 hours during ICU stay in 94 trauma patients,on which the patients were grouped.ResultsSerum levels of ionized calcium decreased as ISS and APACHEⅡ scores increased（P0.01）,which were lower,but ISS and APACHEⅡ scores were higher,in death group than those in survial group（P0.01）.Conlusion Serum ionized calcium determination is helpful in evaluating the severity of trauma and predicting the prognosis.
