人工心脏瓣膜材料及瓣膜置换过程中的麻醉问题

Artificial heart materials and anaesthesia during valve replacement

心脏瓣膜置换适用于先天性或后天性原因造成的瓣膜畸形或变形。通过置换技术能有效解决心脏瓣膜病所致的循环动力学改变,改善患者的生活质量。心脏瓣膜患者的心肺功能代偿能力差、尤其是心肌收缩力和能量储备功能下降,给手术和麻醉带来了一定的难度。因此,在麻醉中要重视用药的合理性,并且根据病情的变化随时调整用药,力求使患者安全度过麻醉关。文章对心脏瓣膜置换术中麻醉注意的事项进行探讨。

Cardiac valve replacement was applied to treat congenital/acquired valve deformity or distortion,which can solve the dynamics changes and ameliorate life quality of valvular disease patients.During the cardiac valve replacement,anaesthesia was more important due to the poor compensation and cardiorespiratory function,especially the decline of myocardial contractile force and energy charge.Thus,the individuated selection of anesthetic should attract more attention.Here,the announcements of anaesthesia during cardiac valve replacement were explored.
