【摘要】:目的分析新生儿高胆红素血症换血疗法与胆红素下降趋势及影响因素,探讨换血治疗量效关系,为减少新生儿换血用量同时达到满意的临床治疗效果提供科学依据。 方法应用回顾性方法收集广西医科大学第一附属医院儿科新生儿病房2005年1月~2011年12月因新生儿高胆红素血症入院,已进行换血治疗且临床资料完整的118例新生儿作为研究对象,收集一般资料,按换血前血清总胆红素浓度分为Ⅰ组(~342μmol/L)、Ⅱ组(~428μmol/L)、Ⅲ组(~513μmol/L)、Ⅳ组(≥513μmol/L),观察换血过程中胆红素浓度变化,分析影响胆红素换出率的因素。比较单倍换血、介于单双倍之间、双倍换血3组患儿光疗时间差异性。数据采用SPSS13.0进行统计分析。 结果(1)随着换血量增加,胆红素值明显下降。在相同换血量下,各组胆红素值差异均有统计学意义(p<0.05)。Ⅰ~Ⅳ组单倍换血后胆红素值分别为169μmol/L、215μmol/L、299μmol/L、380μmol/L;Ⅰ~Ⅳ组介于单双倍换血后胆红素值分别为165μmol/L、198μmol/L、214μmol/L、276μmol/L;Ⅰ~Ⅳ组双倍换血后胆红素值分别为137μmol/L、178μmol/L、227μmol/L、286μmol/L。介于单双倍之间胆红素值与双倍换血比较差异均无统计学意义(p>0.05)。(2)在相同换血量下,各组胆红素换出率差异均无统计学意义(p>0.05),在单倍、介于单双倍、双倍换血量时分别为35.3±12.6%、51.3±6.0%、52.1±9.2%,其升高幅度呈先快后慢,介于单双倍之间胆红素换出率与双倍换血比较差异均无统计学意义(p>0.05)。(3)单个病因较多个病因平均胆红素换出率高(p<0.05)。G-6-PD酶活性对胆红素换出率的影响有统计学意义(p<0.05),且呈正相关。(4)单倍换血结束后平均胆红素浓度仍高,但3组患儿光疗时间无统计学意义(p>0.05)。 结论(1)换血治疗新生儿高胆红素血症疗效显著,,胆红素换出率不受换血前胆红素值的影响,呈先快后慢的趋势上升。(2)初始胆红素值<428μmol/L,推荐单倍换血;对于初始胆红素值≥428μmol/L,建议使用介于单双倍换血。(3)若患儿存在有多个病因,尤其是G-6-PD缺乏症,建议增加换血量以提高胆红素换出率。
