In order to evaluate the result of intraoperative TEE monitoring for cardiothoracic surgery, 113 patients were involved in this study. They included 65 males and 48 females, with an average age of 48.8 +/- 16.6 years, ranging from 10 to 74 years. The pre-operative diagnoses consisted of 41.6 per cent coronary artery disease, 34.5 per cent valvular disease, 12.4 per cent congenital heart disease, 8 per cent aortic aneurysm or aortic dissection, and 3.5 per cent of miscellaneous. The TEE appeared to provide accurate information by beating to changes in the left ventricular preload and contractility in all patients. The severity of valvular dysfunction, intracardiac air/mass, Swan Ganz catheter position, sites of congenital heart defect and aortic dissection were either assessed or reconfirmed during the operation. The ease of TEE technique was satisfactory, since unsuccessful attempt was observed in only 1.8 per cent. One patient died from rupture of thoracic aortic dissection which was related to TEE probe insertion. These data suggest the favorable result of intraoperative TEE as a valuable tool for monitoring in cardiothoracic surgery. Although the technique is simple, special precaution must be observed for patients suffering from acute aortic dissection.
为了评估术中经食管超声心动图（TEE）监测在心胸外科手术中的效果，本研究纳入了113例患者。其中男性65例，女性48例，平均年龄48.8±16.6岁，年龄范围为10至74岁。术前诊断包括41.6%的冠状动脉疾病、34.5%的瓣膜疾病、12.4%的先天性心脏病、8%的主动脉瘤或主动脉夹层，以及3.5%的其他杂症。TEE似乎能通过检测所有患者左心室前负荷和收缩力的变化提供准确信息。术中对瓣膜功能障碍的严重程度、心内气体/肿物、 Swan Ganz导管位置、先天性心脏缺损部位和主动脉夹层进行了评估或再次确认。TEE技术的易用性令人满意，因为仅1.8%的尝试未成功。1例患者死于与TEE探头插入相关的胸主动脉夹层破裂。这些数据表明术中TEE作为心胸外科手术监测的一种有价值工具取得了良好效果。尽管该技术简单，但对于患有急性主动脉夹层的患者必须采取特殊预防措施。
