目的探讨心外膜超声心动图在心脏外科手术中的应用价值。方法采用成人及儿童经胸超声探头,体外循环开放并复跳后行心外膜超声心动图对258例心脏手术患者行术中监测,提供瓣膜功能情况、左心室收缩功能、有无残余分流等信息。结果 98例常规排气后示心腔积气,排气后超声显示至积气消失。8例(换瓣或室壁瘤切除术)探查发现节段性左室壁功能异常,8例瓣膜成形术后示反流偏多,5例瓣膜置换术发现瓣周偏多反流,3例室间隔缺损修补术探查发现较多残余分流,均再次转机修补后分流消失,无感染、出血、严重心律失常等并发症发生。结论心外膜超声心动图操作简易,适应证广,能够即刻评价手术疗效,在心脏外科手术中具有一定临床应用价值。
Objective To investigate the value of epicardial echocardiography in cardiac surgery. Methods Adult and children with transthoracic ultrasound probe, cardiopulmonary bypass was opened and re-epicardial epicardial echocardiography after 258 cases of cardiac surgery underwent intraoperative monitoring, to provide valvular function, left ventricular systolic function, with or without residual shunt information. Results 98 cases of conventional ventricular gas showed after exhaust, after the exhaust gas showed disappearance of gas. 8 cases (flap or aneurysm resection) exploration showed segmental left ventricular dysfunction, 8 cases of valve retrograde flow showed more, 5 cases of valvuloplasty found partial flap regurgitation, 3 cases Ventricular septal defect repair found that more residual shunt, are again transferred to repair the shunt disappeared, no infection, bleeding, severe arrhythmia and other complications. Conclusion Epicardial echocardiography is easy to operate and has a wide range of indications. It can evaluate the curative effect immediately and has certain clinical value in cardiac surgery.
