多血质貌新生儿血黏度检测的研究

Study of Blood-Viscosity in Sanguineous Neonates

目的研究多血质貌新生儿血黏度的变化，并对其临床表现、实验检测项目与检测的理想时间进行探讨。方法对有临床症状的69例多血质貌新生儿（排除有慢性缺氧史患儿）进行微量血气分析：血红蛋白（Hb）、血球比积（Hct）和血液流变学检测等。治疗36～72h后复查。结果69例新生患儿Hb〉200g／L；Hct〉0．6；血液流变学显示：血黏滞度各项测定值均明显高于正常参考值。治疗前后Hb、Hct、血液流变学的差异呈显著性（P〈0．001）。结论多血质貌新生患儿虽Hb、Hct值未达红细胞增多症的诊断标准，但血液黏稠度明显增高，需及时进行相关调整和治疗。新生儿出生3～4d后，为血液流变学检测的较为理想时间。

Objective To explore the symptoms, diagnostic markers, and the relations between them for sanguineous neonates, and analyse the optical time for blood-theology test. Methods Blood analysis was performed in order to get Hb, Hct, and blood-theology data for 69 sanguineous neonates. Blood analysis was performed again after they were treated 36 -72 hours. Results The value was higher than 200 g/L for Hb and higher than 0.6 for Hct for.all 69 sanguineous the normal value. There was significant difference i dnd blood- rheology datd （ P 〈 0.001 ）. Conclusion neonates. The blood-rheology results were also higher than between before treatment and after treatment for Hb, Hct, Sanguineous neonates should be actively treated because of higher blood- rheology, although they can not be diagnosed as polycythemia according to Hb, Hct value. 3 4 days after birth are the optical time for blood-rheology test.
