摘要
目的:探讨彩色多普勒组织显像在小儿贫血心脏改变中的应用价值。方法:采用彩色多普勒组织显像(DTI)观察25例贫血患儿二尖瓣环收缩期及舒张早期运动速度(MVR-SV及MVR-DEV)和左室后壁心肌收缩期及舒张期运动速度(MSV及MDV),结合M型超声测定左室收缩功能[心指数(CI)及射血分数(EF)],并进行统计学处理。结果:观察1组CI及MVR-SV较对照组差异有显著意义(P<0.05);观察2组MVR-DEV及MDV较对照差异有显著意义(P<0.05)。结论:多普勒组织显像技术可动态观察贫血患儿心功能情况,是检测心功能最敏感而可靠的参考指标。
Objective：To explore the application value of color Doppler tissue imaging （DTI） in children with anemia, Methods：The velocity of mitral valve ring and the left ventricular posterior myocardial wall in systole and early diastole （MVR-SV, MVR-DEV, MSV, MDV） was observed by using DTI in 25 children with anemia. The function of left ventricle include cardiac index （CI） and ejection fraction （EF） was measured combined with M-Doppler. Each was compared with file paired control group dynamically. Results： CI and MVR- SV of the first group were significandy higher than the control group （ P 〈 0.05）, MVR-DEV and MDV of the second group were signifi- candy lower than the control group （ P 〈 0.05）. Conclusion： DTI technology could observe cardiac function of the children with anemia, and it is a sensitive and reliable referential criteria in evaluating cardiac function.
