During operation, 102 patients were continually monitored for heart function using transoesophageal echocardiography. Echo-contrast particles (mostly of mi-minute echo-contrast particles were also monitored through the right and left hearts. The most frequent and significant evidence was found in the right heart in the left ventricle. The authors discuss the etiolo-less frequent and less significant in abdominal operations (57%). In 27% patients undergoing chest surgery, minute echo-contrast particles were also monitored in the left ventricle. The authors discuss the etiology (fat droplets, marrow particles, thrombotic material, air) as well as the clinical significance of the monitored findings. With the exception of orthopedic patients, where even large particles were sporadically observed to pass through, these findings are of no clinical significance.
手术期间，使用经食管超声心动图对102例患者的心脏功能进行持续监测。还通过左右心脏监测了超声造影剂颗粒（主要是微小的超声造影剂颗粒）。最常见且显著的证据出现在右心和左心室。作者讨论了病因（脂肪滴、骨髓颗粒、血栓物质、空气）以及监测结果的临床意义。除了骨科患者偶尔会观察到甚至大颗粒通过外，这些发现无临床意义。在腹部手术中出现频率较低且意义较小（57%）。在27%接受胸部手术的患者中，左心室也监测到微小的超声造影剂颗粒。
