经颅多普勒超声在新生儿肺炎中的应用研究

Application study of transcranial Doppler ultrasound (TCD) in neonatal pneumonia

目的 :探讨TCD在新生儿肺炎中的应用价值 ,为临床诊治及观察病情提供依据。方法 :对 2 6例正常新生儿和2 5例肺炎新生儿分别进行TCD检查 ,将所测大脑中动脉 (MCA)、大脑前动脉 (CAC)、大脑后动脉 (PCA)血流各参数及状态进行比较。结果 :新生儿肺炎组双侧MCA各血流参数及右侧PCA的Vd、Vm均增高。结论 :TCD为新生儿肺炎提供了一种安全无创的检查手段 ,可作为判断和监测新生儿肺炎通气功能障碍的一个辅助指标。

Objective:To discuss the application value of TCD in neonatal pneumonia.Methods:26 normal newborns and 25 newborns with pneumonia were respectively detected by TCD.The blood flow velocities of middle cerebral artery(MCA),anterior cerebral artery (ACA) and posterior cerebral artery(PCA) from the group with pneumonia were compared with those from the normal group.Results:All blood flow velocities of two side MCA,Vd and Vm of right PCA from the group with pneumonia were higher.Conclusion:TCD is a useful noninvasive test means for neonatal pneumonia and it can be used to be an auxiliary index for judging and observing the dysfunction of pulmonary ventilation of newborns with pneumonia.
