A computerized system for postoperative autotransfusion with on-line feedback of left atrial pressure and other relevant variables is in routine use in the cardiac surgical intensive care unit at University Hospital, the University of Alabama at Birmingham, USA. The autotransfusion subsystem was integrated into an existing intensive care computer system that monitors and stores physiological data. The autotransfusion system decreases the need for bank blood and lessens the chance for patient exposure to complications possible with homologous blood transfusion. The fully automated system promotes greater hemodynamic stability than other techniques of postoperative autotransfusion. Closed-loop autotransfusion is less labor-intensive than manual methods and has proved to be cost-effective.
美国阿拉巴马大学伯明翰分校大学医院心脏外科重症监护病房常规使用一种术后自体输血计算机系统，该系统可对左心房压力及其他相关变量进行在线反馈。自体输血子系统被集成到一个现有的重症监护计算机系统中，该系统可监测和存储生理数据。自体输血系统减少了对库血的需求，并降低了患者因同种异体输血而可能出现并发症的几率。与其他术后自体输血技术相比，该全自动系统能促进更高的血流动力学稳定性。闭环自体输血比手工方法所需的劳动力更少，且已被证明具有成本效益。
