Methods: Nitroglycerin at doses ranging from 0.4 to 0.8 μg·kg
was administered intravenously to 15 infants and small children with VSD and congestive heart failure under continuously monitoring heart rate(HR) and blood pressure(BP), left ventricular ejection fraction(EF), fractional shortening(FS), pulmonary artery mean pressure(PAMP), pulmonary capillary wedge pressure(PCWP) and left ventricular wall stress(LVWS) were measured by echocardiography before and at 1 and 6 hours after administration of nitroglycerin. Results: PCWP was reduced from (2.8±0.4) kPa before administration of nitroglycerin to (1.7±0.4) kPa at 1 h and (1.6±0.4) kPa at 6 h after administration of nitroglycerin(

Intravenous nitroglycerin (NTG) has been widely used in the treatment of the congestive heart failure because of its effect of vasodilatation. However, less well known is hemodynamic effect of NTG in children, especially infants with
heart failure. The purpose of the study was to investigate the effect of intravenous NTG on hemodynamics in infants with congestive heart failure secondary to congenital heart defects of left
right shunts. Methods
Twenty six infants with the mean age of 10 months were investigated clinically. Continuous monitoring of the heart rate, blood pressure and total peripheral resistance was done. The echocardiography was used to measure the left ventricular ejection fraction, left ventricular end diastolic volume index, pulmonary capillary wedge pressure, mean pulmonary artery pressure and left ventricular wall stress(LVWS) before the administration of NTG and at the administration with dosages of 0.5, 1.0, 1.5, 2.5 and
5.0 μg/(kg·min),
respectively. Results
Intravenous NTG had no significant effect on the hemodynamic indexes including the heart rate, blood pressure, ejection fraction, stroke volume index, cardiac output index and left ventricular end diastolic volume index in infants with congestive heart failure. At the dosage of
0.5 μg/(kg·min),
the pulmonary capillary wedge pressure decreased from (15.5±2.3) mm Hg before the use of NTG to
(14.3±2.2)
mm Hg after the use of NTG, and reached a minimum pressure of
(12.3±2.4) mm Hg. After the administration of NTG, the LVWS I, II and III decreased from (407±65 )
(255±52) N/cm
to (357±75) N/cm
,(136±48) N/cm
and (218±52)
<0.05), respectively, and reached the minimum level of (321±50) N/cm
,(187±42) N/cm
, respectively. With a higher dosage of 2.5 μg/(kg·min), decreases in peripheral vascular resistance and mean pulmonary arterial pressure ?were ?evident ?(
<0.05), ?while the above indexes did not show any statistical difference among the different dosages. Conclusion
The congestive heart failure secondary to congenital cardiac defects of left
right shunts in infants was proved to be the indication of using intravenous NTG to improve hemodynamics. There was a different dosage selectivity between artery and venous vasodilatation, but the
hemodynamic changes were independent of dosages. The dosages of 0.5 and 1.0 μg/(kg·min) NTG were recommended on the purpose of decreasing the cardiac preload in the treatment of the heart failure.目的　了解不同剂量硝酸甘油 (NTG)对左向右分流型先天性心脏病合并心力衰竭患儿血流动力学的影响。方法　连续监测 2 6例患儿的心率、血压、总外周阻力 (TPR) ,分别于用药前及用药 0 .5、1.0、1.5、2 .5、5 .0 μg

引起低射血分数的症状主要是什么？
发布时间：
&&&编辑：丁立刚

　　低射血分数则是指射血分数低于正常百分比。主要是心室异常扩大、心室功能减退。病人在出现心功能不全时往往伴有射血分数的降低。当射血分数值降低至35%以下时发生恶性心律失常猝死的机会就大大增加。那么引起低射血分数的症状主要是什么呢？　　心室异常扩大：心室扩大主要见于肺动脉高压的患者。常见的病因有慢性肺源性心脏病，肥厚性心肌病等。　　心室功能减退：心室功能减低，可以造成血泵不足影响机体的代谢从而引起一系列以循环障碍为主的综合征。原因很多如慢性心功能不全（慢性心衰）；冠心病、高血压引起的心脏负荷过重；心肌缺血、肥厚性心脏病、心包疾病等。另外糖尿病也会引起这种状况。　　肺动脉段延长：肺纹理增粗增多说明气道的支气管有堵塞造成这原因有很多种常现的是支气管炎有支气管哮喘的患者也会这样其他的物质刺激也会出现支气管痉挛长期的支气管收缩则会造成肺纹理增粗、增多这些物质可以是空气中的粉尘也可以是汽车尾气也可以是二手烟如果有过敏史的话会对一些猫狗的毛毛、花粉、冷空气之类的物质引起支气管痉挛。　　心横径增大：心横径增大包括各种病理类型的动脉管壁变性和硬化的总称.动脉硬化是动脉的一种非炎性退行性和增生性蹭这种蹭可导致动脉管壁增厚变硬管腔变狭动脉失去弹性.常见的动脉硬化类型有动脉粥样硬化动脉中层钙化和小动脉硬化3种.脑动脉硬化症是指脑动脉粥样硬化小动脉硬化玻璃样变等动脉管壁变性所引起的非急性弥漫性脑组织改变和神经功能障碍.临床表现为进行性脑功能减退早期出现神经衰弱综合征后逐渐出现弥漫性器质性脑损害如血管性痴呆帕金森综合征假性球麻痹皮层下动脉硬化性脑病及脑神经麻痹等。　　以上这些症状都可以导致低射血分数。
