摘　　要：用体表及心脏术中经食道超声心动图（ＴＥＥ）经胃研究心脏停跳体外循环时腹部脏器及外周血管的血流灌注，发现腹主、肝、肾、脾动脉显示红或蓝色血流，动脉呈锯齿形搏动性频谱，静脉呈连续性平直频谱，并可计算血流参数，同时在体表检查颈总、眼、及桡动脉血流。经手术前，体外循环前、中、后比较认为：体表及ＴＥＥ术中检测内脏与周围血管灌注，可直接实时的了解血流动态变化。The blood Perfusion of abdominal organs and peripheral vessels during extracorporeal circulation (ECC) was studied by B-mode and transesophageal echocardiography (TEE). During ECC,TEE displayed that the color of the blood flow in hepatic A. splenic A, renal A and abdominal aorta appeared red or blue. The spectrum of arteries was shown as serrate and pulsatile waves and veins flat and continuous waves. The parameters of the blood flows were calculated. The blood flows of common carotid A, opthalmic A and radial A were examined at the same time. Comparing the results obtained before the operation with those before, during and after ECC, it is suggested that using transthoracic and intraoperative TEE to detect the blood perfusion of abdominal organs and peripheral vessels,provides a direct and real time observation of the dynamic changes of blood flow.
