摘要
目的 探索不同体位对生化指标的影响。方法 10 7名志愿者 ,经交叉同体配对设计 ,分冬、春、夏 3批 ,抽坐、卧两种姿势同一部位的血液 ,其中 19名分别抽站、坐 15min、卧 15min、30min、再坐 15min标本 ,在自动生化分析仪上配对分析 32项指标。结果 以卧位为基线与坐位相比 ,2 5项生化检测结果差异有非常显著意义 (P <0 0 0 1) ,3项差异有显著意义 (P <0 0 5 ) ,从卧位到立位结果逐渐升高 ,依次为卧位 <坐位 <立位 ,平均升高 11 49% ,最高升 5 5 39%。卧位后坐 15min ,各指标可回复到原坐位的 94%以上 ,季节、年龄与体位改变无关 ,与性别有关 ,无机磷 (IP)、尿酸 (UA)、肌酐(Cre)、葡萄糖 (Glu)差异无显著意义 (P >0 0 5 )。结论 体位改变能引起 2 8项生化指标的显著生理变异 ,与蛋白质相关的项目变异尤为显著 ,致使正常边缘数值出现异常结果。提示在分析实验数据时不要忽视体位因素 ,以免引起误导。
Objective To investigate the affect of body positions on biochemical indexes. Methods By autogenous contrast and cross matched survey, 107 volunteers divided into 3 season patches of winter, spring and summer, blood samples were drawn from the same part in both standing and lying positions。From19 persons, blood samples were collected respectively after standing and sitting for 15 min, lying for 15 min and 30 min and then sitting for another 15 min。 The blood samples were analyzed for 32 biochemical indexes on analyzer。Results 25 biochemical indexes in sitting position were significantly different from those in lying position (P<0。001), 3 indexes had greater differences (P<0。05)。 The values increased successively from lying, sitting and standing position, with the average rate of 11。49% and 55。39% at the most. While sitting for 15 min after lying, These indexes returned to 94% of the original value in sitting position. Season and age had no relationship with body position except Sex. IP?UA?CRE and Glu had no significant differences(P>0。05)。Conclusions Changing body position can result in obvious physiological variation of 28 biochemical indexes, particularly of those related to protein. Such result may lead to abnormality in some marginal values. It suggests body position should not be neglected in analyzing laboratory data.
