title: Analysis of cardiopulmonary bypass status in China: eight-year development trends.
abstract: OBJECTIVE
  To study the development of cardiopulmonary bypass (CPB) in the past 8 years and to come up with predictions and recommendations for the future in China.
  
  
  METHODS
  Domestic hospitals performing cardiovascular operations were supplied with questionnaires, annually (between 2003 and 2008), upon the number of on-pump and off-pump cardiovascular operations, oxygenators of different types and the number of extracorporeal membrane oxygenation (ECMO). All the hospitals in this study were divided into 8 grades, according to the number of cardiovascular operations. The market share of hospitals in each grade was analyzed.
  
  
  RESULTS
  The total anumber of cardiovascular operations was 170,547 in 2010, of which 136,753 were performed under CPB. The ratio of imported membrane oxygenators increased from 43.22% in 2003 to 59.75% in 2010, while bubble oxygenator composition decreased from 43.78% in 2003 to 14.59% in 2010. Forty-four hospitals carried out 206 cases of ECMO in 2010. There were 32 hospitals that performed cardiovascular operations of over 1,000 cases and their market share was 43%. There were 255 hospitals that performed cardiovascular operations in less than 50 cases and their market share was only 3%.
  
  
  CONCLUSIONS
  CPB in China has gone through a rapid development in the past eight years. Medical resources for CPB should be concentrated and systematic training regulations should be established in the future.
