目的 :观察新生儿脐血的血液粘度、血浆粘度、红细胞压积、血沉、红细胞电泳情况。方法 :新生儿分娩断脐后立即抽取脐血 4ml+肝素抗凝 ,并立即送检 ,采用北京普利生 L BY- N6 A自清洗旋转式粘度计检验。结果 :母体为正常生理妊娠的新生儿组 :全血低切粘度 8.91± 6 .79m pa· s,全血高切粘度 5 .6 6± 2 .0 mpa· s,血浆粘度 1 .46± 0 .2 4m pa· s,红细胞压积 5 0 .1±1 8.4% ,血沉 2 .1 4± 1 .36 mm/ h,红细胞电泳 1 5 .82± 3.79s;母体为妊高征的新生儿组 :全血低切粘度 1 1 .96± 7.38m pa· s,全血高切粘度 6 .48± 1 .5 7mpa· s,血浆粘度 2 .5 3± 1 6 .4mpa· s,红细胞压积 31 .47± 0 .35 % ,血沉 1 .6 8± 1 .43mm/ h,红细胞电泳1 5 .6 8± 3.43s;正常妇女组 :全血低切粘度 2 2 .33± 6 .88mpa· s,全血高切粘度 4.5 0± 0 .5 4mpa· s,血浆粘度 1 .73± 0 .0 9mpa· s,红细胞压积 41 .0 9± 2 .6 0 % ,血沉 1 7.0 9± 6 .35 mm/ h,红细胞电泳 2 1 .0 4± 1 .44 s。结论 :孕期母体血液流变学变化对新生儿影响较小
OBJECTIVE: To observe the blood viscosity, plasma viscosity, hematocrit, erythrocyte sedimentation rate, erythrocyte electrophoresis in neonatal cord blood. Methods: Neonatal umbilical cord immediately after the umbilical cord blood 4ml + heparin anticoagulation, and immediately submitted for inspection, using Beijing Pulisheng L BY-N6 A self-cleaning rotary viscometer test. Results: The neonates with normal pregnancy were: the low blood viscosity of whole blood 8.91 ± 6 .79m pa · s, the high blood viscosity of whole blood 5.66 ± 2.0mPa · s and the blood viscosity 1.46 ± 0 .2 4m pa · s, hematocrit 51 ± 1 8.4%, erythrocyte sedimentation rate 2 .1 4 ± 1 .36 mm / h, erythrocyte electrophoresis 15.82 ± 3.79s; Group: Whole blood low shear viscosity 1 1 .96 ± 7.38m pa · s, whole blood high shear viscosity 6 .48 ± 1 .5 7mpa · s, plasma viscosity 2. 53 ± 1 6 .4mpa · s, hematocrit Product 31.47 ± 0.35%, ESR 1.68 ± 1.43mm / h, erythrocyte electrophoresis 15.68 ± 3.43s; normal women group: whole blood low shear viscosity 22.33 ± 6.88mpa · S, whole blood viscosity of high shear 4.5 0 ± 0.54mpa · s, plasma viscosity of 1 .73 ± 0. 9mpa · s, hematocrit 41 .0 ± 2. 60%, erythrocyte sedimentation rate 1 7.0 9 ± 6 .35 mm / h, erythrocyte electrophoresis 2 1 .0 4 ± 1 .44 s. Conclusion: Maternal blood rheology changes during pregnancy have less effect on neonates
