Abstract

Comparison study of pneumatic VAD and PCPS. In past 13 years, we had 16 pneumatic ventricular assist device (Group-I) and also 16 percutaneous cardiopulmonary support patients (Group-II), as a cardiac support for postcardiotomy cardiogenic shock. Using those patients, comparison study was performed, examing drainage volume, haemolysis, intubation time and weaning rate. Drainage volume were much in the Group-I during assist. Platelet count decreased early after assist in the group-II. There were no differences in haemolysis between the two groups. Early extubation and primary sternal closure were possible in the Group-II. Weaning rate of Group-I was better than that of Group-II, however survival rate of Group-II was better than that of Group-I. In the PCPS cases that obtained enough assist flow, there were few cases complicated with multiple organ failure (MOP). In case of post-cardiotomy cardiogenic shock or low output syndrome, PCPS system should be applied firstly under IABP assist become of its simplicity and low cost. Thereafter, VAD should be used in case of refractory to PCPS and more longer support duration.
