本组病人采用贺斯和林格式液补充容量。应用自体血回收Hb维持在10g•dl-1以上。必要时应用硝酸甘油。其中11例静点加用多巴胺5~10μg•kg-1•min-1、另外6例静点肾上腺素0.015~.2μg•kg-1•min-1。 结论,非体外循环心脏不停跳冠状动脉搭桥术可造成血流动学的剧烈波动,通过合理用药调整,可以维持血流动力学的稳定。外科医生的操作和手术时间的长短对病人心功能的影响也密切相关。<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 参考文献 1.Fernando G. et al: Complete myocardial revascularization on the beating heart with epicardial tabilization; Anesthetic Considerations; Journal of cardiothoracic and vascular anesthesia.
