左心室辅助泵是指部分或全部代替左心室功能的机械装置,种类繁多。这方面的研究工作,近年来在许多研究中心有了不少进展,从暂时性气动泵到长期电动或热(核)能驱动装置都有所发展,其中一些研究中心已在动物实验基础上进一步试用于临床,对于严重左心衰竭、心源性休克、心脏大手术后不能脱离体外循环的病人,起到了减轻左心室负荷、短期内维持有效循环,有利于心功能恢复的作用,为抢救危重心脏病人,开展更复杂的心血管手术和术后扶持病人,提供了一条颇有希望的途径。目前供临床试用的多为暂时性左心室辅助泵,一般辅助循环时间从数小时至数周。这种
Left ventricular assist pump refers to some or all of the mechanical devices to replace left ventricular function, a wide range. Research work in this area has made a lot of progress in many research centers in recent years, from temporary pneumatic pumps to long-term electric or thermal (nuclear) energy-driven devices. Some of these research centers have further developed on the basis of animal experiments Trial for clinical use, for patients with severe left ventricular failure, cardiogenic shock, cardiac surgery can not escape from the cardiopulmonary bypass, played a reduction in left ventricular load, maintain an effective short-term circulation is conducive to the recovery of cardiac function, for the rescue of critically ill patients Heart patients, to carry out more complex cardiovascular surgery and postoperative support to patients, provides a promising way. Currently available for clinical trial mostly temporary left ventricular assist pump, the general auxiliary cycle time from hours to weeks. This
