Abstract: 目的探讨新生儿窒息时一氧化氮(Nitrogen monoxide,NO)、一氧化氮合成酶(Nitrogenmonoxide syntase,NOS)水平的变化及其对判断预后的指导意义.方法采用比色等方法测定32例窒息新生儿及30例正常新生儿血浆一氧化氮、一氧化氮合成酶活性水平.结果正常对照组NO、NOS水平分别为(72.84±12.35)μmol/L和(O 203±0.05)U/mg,窒息组为(129.80±32.66)μmol/L和(0.352±0 124)U/mg;其中轻度窒息组为(105.65±36.30)μmol/L和(0.289±0.09)U/mg;重度窒息组为(144.55±26.32)μmol/L和(O.364±0.010)U/mg.窒息新生儿NO、NOS水平较正常新生儿明显升高(P<O.01),重度窒息惠儿较轻度窒息患儿升高(P<0 01).结论 NO、NOS水平高低与窒息新生儿脑损伤程度和预后有关,可作为判断新生儿窒息及其所致新生儿缺氧缺血性脑病(HIE)病情及预后的指标之一.
