| 摘 要： | 目的:探讨早产儿血清胆红素增高导致神经系统损害时其血清胆红素临界值,以及影响临界值的高危因素。方法:收集2000年1月至2002年12月在我院新生儿科住院的早产儿高胆红素血症患儿病例共167例,以脑干听觉诱发电位(BAEP)出现异常作为神经损害标志。入院后即检测血清胆红素浓度及脑干听觉诱发电位,当出现皮肤黄疸后每日检测血清胆红素浓度及脑干听觉诱发电位一次,直至脑干听觉诱发电位出现异常,并记录出现异常时对应的血清胆红素值。同时记录各患儿的胎龄、出生体重、血清白蛋白值和血pH值。结果:167例早产儿中引起脑干听觉诱发电位异常时,血清间接胆红素临界值为(177.41±27.23)μmol/L。对于出生胎龄<32周、～34周、～36+6周的患儿,导致脑干听觉诱发电位异常时,血清间接胆红素临界平均值分别为(154.67±28.92)μmol/L、(161.61±16.06)μmol/L和(173.76±19.22)μmol/L。应用二元变量相关分析研究,提示出生胎龄、出生体重、血清白蛋白浓度及血pH值均与血清间接胆红素临界值有相关性,其相关系数分别为0.653、0.698、0.593和0.512,P值均<0.001。结...

| Abstract: | Objective To explore the critical value of serum bilirubin impairing center nerve cell,and these factors of influencing critical value of serum bilirubin.Methods One hundred and sixty-seven cases of premature infants suffer from hyperbilirubinemia were admitted in our hospital between Jan.2000 and Dec.2002.With risk of value of serum bilirubin,that brainstem auditor evoked potential (BAEP) was became abnormal,it was the mark of impairment of center nerve cell.The concentration of serum bilirubin was assayed... |
