Objective To investigate the development trends of domestic cardiopulmonary bypass(CPB) in the past eight years.Methods Domestic hospitals that carry out cardiovascular sugeries were inquired with questionnaires annually up-on the number of on-pump and off-pump cardiac operations,oxygenators of different types and extracorporeal membrane oxygenations.Classify all the hospitals according to the cardiac surgery amount.Analyze the market share of each grade and the composition of oxygenators.Results The sum amount of cardiac operations and CPB were 170 547 and 136 753 respectively in 2010.In 2010,the composition of imported membrane oxygenator climbed up to 59.75％ from 43.22％ in 2003,while bubble oxygenator composition decreased from 43.78％ to 14.59％.44 hospitals carried out ECMO in 2010 and the sum number of ECMO was 206.The market share of hospitals( 32),with cardiac surgery number over 1000 per year,was 43％.Conclusion CPB in China has went through a rapid development in the past eight years.Medical resources of CPB should be concentrated and normal and systematic train regulations should be established in the future.%目的 了解近8年来中国体外循环的发展动态,对我国未来体外循环的发展提出预测和建议.方法 2003年至2010年,逐年对全国开展心脏手术的医院进行问卷调查,内容涉及开展体外循环(on-pump)心脏手术和非体外循环(off-pump)心脏手术例数、氧合器使用情况及体外膜肺氧合(extracorporeal membrane oxygenation,ECMO)例数.收集并计算各年度各类氧合器的使用构成比；按手术例数对医院进行分级,计算不同级别医院所占比例.结果 2010年全国心脏手术170 547例,其中体外循环136753例.2010年进口膜式氧合器使用比例较2003年升高(59.75％对43.22％),鼓泡式氧合器比例显著降低(43.78％对14.59％),国产膜式氧合器使用比例也有所升高(13.00％对25.66％).2010年全国开展ECMO的医院共44家,总例数206例；年手术量＞1000例的医院32家,占43％；手术量＜50例的医院255家,占3％.结论 中国体外循环近年来发展速度较快,膜式氧合器使用率逐年上升,鼓泡式氧合器使用率逐年下降；未来需进一步集中体外循环医疗资源.
