【摘要】 目的 :探讨体外循环术后超声监测的临床意义。方法 :采用超声诊断仪对 10 7例体外循环心内直视手术患者术后早期行心脏、胸腔及肝脏扫查 ,根据病情变化每天或间隔 1～ 2 d检查 1～ 2次。结果 :经超声检查发现心包填塞 7例 (6 .5 % ) ,心肌收缩力减弱引起的低心排血量综合征 8例 (7.5 % ) ,二尖瓣置换术后感染性心内膜炎并瓣周漏 1例 (0 .9% ) ,胸腔积液 5 1例 (4 8.7% ) ,术后肝脏反而增大者 5例 (4 .7% )。经采取适当治疗措施后大部分患者好转 ,3例死于心肌收缩力减弱引起的低心排血量综合征。结论 :超声监测为部分体外循环术后心肺并发症的早期诊断和正确处理提供了依据 ,特别是对心包填塞和心肌收缩力减弱引起的低心排血量综合征的鉴别诊断具有确诊价值 ,对观察术后心功能变化及指导临床用药具有重要意义。更多还原

【Abstract】 Objective:To explore the significance of ultrasonography monitoring after cardiopulmonary bypass.Method:107 patients′ heart,thorax and liver were detected by ultrasonography and the detecting frequency was either once to twice a day or once every one to two days depending on patients′ condition after cardiopulmonary bypass.Result:Postoperating complication detected by ultrasonography included pericardial tamponade in 7 cases ( 6.5 %),low cardiac output syndrome in 8( 7.5 %),bioprosthetic valve endocarditis with perivalvular leaks in 1( 0.9 %),pleural effusion in 51( 48.7 %),postoperating liver enlargement in 5( 4.7 %).Most of them were mending micely and 3 cases died of low cardiac output syndrome after proper treatments.Conclusion:Ultrasonography monitoring offered more evidences for the early diagnosis and correct treatment of postoperative complication after cardiopulmonary bypass.Furthermore,it had especially important value for differentiating pericardial tamponade and low cardiac output syndrome,and might be supperior for observing the postoperative heart function and guiding the drug apply.更多还原
