窒息新生儿多器官血流动力学和心脏功能的研究

目的 研究新生儿多脏器损伤的机理，提供早期诊断方法。方法 应用Ｕｌｔｒａｍａｒｋ－９（ＨＤＩ）采用超声诊断仪等研究同一窒息儿脑、肾、胃肠血流动力学和心脏功能的变化。结果：（１）新生儿窒息后各脏器血流灌流量均减少，但程度不一致，以肠道最先受累且程度重恢复最慢；（２）心功能障碍是窒息的常见并发症，其特点是舒张功能首先受累，收缩功能障碍则右室重于左室；（３）低氧血症是新生儿窒息的病理生理基础，且与各脏器

Study on the Hemodynamics of Multiple Organs and Cardiac Function in Asphyxiated Neonates

Objective:To study the pathogenesis of multiple organs in asphyxiated neonates and to offer early diagnostic methods.Methods:The changes of hemodynamics of brain,kidney,gastrointestinal tract and heart function in thirty asphyxiated newborn infants were examined by using Ultramark 9 ultrasonography.Results:(1)The blood perfusion of organ involved was decreased with different degree;(2)Cardiac dysfunction was the common complication,right ventricular systolic dysfunction was dominated.The diastolic dysfunction appeared earlier than systolic dysfunction;(3)The hypoxemia was the important pathophysiologic basis of the organ damage and significantly correlated with the degree of the organs involved.Conclusion:Neonatal asphyxiated will induce hemodynamic disturbance of many organs including the heart.
