In order to assess the utility of contrast M-mode echocardiography in an intensive care nursery population of critically ill newborns with cardiac and pulmonary disease and to validate contrast echo methods, we performed 200 serial contrast echoes on 40 infants via umbilical arterial or venous catheters which had been placed into these infants for clinical indications. The resulting contrast echoes recorded from the precordium or the suprasternal notch allowed the delineation of intra- and extracardiac right-to-left and left-to-right shunting patterns. Patterns identified and validated by cardiac catheterization (in cardiac patients) were: right-to-left atrial shunts, right-to-left ventricular shunts, and left-to-right patent ductus arteriosus shunts. The studies were without complication. Serial application of these echocardiographic techniques was extremely important in assessing changing physiology in these neonates. Contrast echocardiography adds physiologic flow information to the anatomical information available from M-mode echoes and is quite important in the diagnosis and sometimes in the management of critically ill newborns.
为了评估对比M型超声心动图在患有心脏和肺部疾病的重症新生儿重症监护病房人群中的效用，并验证对比回声方法，我们通过因临床指征已置入40例婴儿的脐动脉或静脉导管对其进行了200次连续对比回声检查。从前胸或胸骨上切迹记录到的对比回声能够描绘心内和心外的右向左和左向右分流模式。经心导管检查（针对心脏病患者）识别并验证的模式包括：右向左心房分流、右向左心室分流以及左向右动脉导管未闭分流。这些研究没有并发症。这些超声心动图技术的连续应用在评估这些新生儿不断变化的生理状况方面极其重要。对比超声心动图为M型回声提供的解剖信息增添了生理血流信息，在重症新生儿的诊断乃至有时在治疗中都非常重要。
