Abstract
We evaluated seven patients (group L) introduced heparin coated percutaneous cardiopulmonary support (PCPS) systems maintained over 7 days. The causes of introduction were postcardiotomy shock in 2, acute fluminant myocarditis in 4, acute massive pulmonary embolism in 1. The average age (45.0±17.8) was younger than that (64.0±10.6) of the 55 patients (group S) supported by PCPS within a week. Six patients of group L weaned from the support and five discharged from the hospital, but there was no statistical difference between group S in the weaning and survival rate. Massive hemolysis was observed in three of the group L after 4 or 5 days. The newly developed heparin coated PCPS system may have a feasibility to use over a week. However it seems important to prevent infections and to care attentively for prolonged cardiopulmonary support.
