自1959年我们在西安召开的心血管疾病学术讨论会上把心脑灌注的实验方法及其结果提出来以后国内学者对其操作方法作了很多改进,并根据改进的特点给予不同命名,如半身外特环、选择性低温、低温低流量分量灌注等。在临床工作应用上,这个方法也有更大开展,仅在华北一区就达百次以上。1961年在石家庄召开的心血管学术座谈会上,苏鸿熙及尚德延氏就曾分别把他们的有关心脑灌注中下半身血液动力学的实验观察,作 Since 1959, we held a symposium on cardiovascular disease in Xi’an, and put forward the experimental methods of heart and brain perfusion and its results later, domestic scholars made a lot of improvements to its operation methods and given different naming based on the improved features such as half body Outer special ring, selective low temperature, low temperature and low flow component perfusion. In clinical application, this method has also been carried out more, only one area in North China reached more than 100 times. In 1961 in the cardiovascular symposium held in Shijiazhuang, Su Hongxi and Suntech have respectively put their heart and brain perfusion in the lower body hemodynamic test,
