本文介绍先心病的诊断技术,并结合我们的临床实践经验教训,以供儿科、内科医师参考。病史主诉:小儿先心病很少直接诉述心脏本身,而常诉体重不增、频繁呕吐、吸奶瓶费力、多汗、呼吸增快等。有时母亲怀抱小儿或洗澡时发现胸廓畸形,心跳强烈。青紫:注意询问青紫出现时间,如大动脉错位、三尖瓣闭锁,生后即明显青紫。四联症、肺静脉畸形引流,生后1~6月逐渐青紫。先心病青紫属中心性,即结合膜、口腔粘膜青紫。轻度青紫面颊口唇暗红色。新生儿重度青紫吸氧后不改善,即使听不到心脏杂音,也应高度怀疑先心病。青紫患儿常伴蹲踞姿态,缺氧发作、杵状指趾等,均应注意询问。呼吸困难:呼吸增快,短促费力,安静时呼吸 相似文献

本文采用Low Shear-30流变测定仪研究健康儿童211例的血液粘弹特性,测定指标共10项,确立了小儿正常值。从不同年龄分析,新生儿期呈血高粘滞状态;此外整个儿童时期呈血低粘滞状态。从不同性别分析,10岁以下小儿各指标参数无男女差异;10岁以上小儿开始出现性别差异。以上血液流变学变化与儿童时期的生长发育、解剖生理特点是相适应的。 相似文献

The thixotropic parameters of whole blood in two groups of children with congenital heart disease (CHD) were measured. Group 1. cyanotic heart disease (CCHD), 20 cases; Group 2. acyanotic heart disease (ACHD), 30 cases. Fifty healthy children were controls matched with the patients in sex and age. Their thixotropic parameters were compared; the paired t-test was used. In the children with CCHD, the hematocrit (HCT), the yield stress (tau 0) the Newtonian contribution of viscosity (mu), the equilibrium value of the structural parameter (A), the apparent viscosity at 2.37 sec-1 (eta s) and the Non-Newtonian contribution of viscosity (eta s-mu) were significantly higher than those in corresponding control groups. In the children with ACHD, only the values of tau 0, eta s-mu, and eta s were higher than those in control groups. All of the thixotropic parameters in CCHD group were significantly higher than those in ACHD group. Thus we described quantitatively CHD in terms of thixotropy of blood. The thixotropic parameters of blood could be used as indexes of severity for pathologic changes of CHD. 相似文献
