✦ Synopsis

the Haemocell System 350 cell saver Autotransfusion was performed during elective abdominal aortic reconstruction in ten patients using the recently developed Haemocell System 350. A mean of 60 per cent of total blood loss was salvaged, and during operation each patient was autotransfused I unit. Good preservation of cellular components, including platelets, was seen after processing with the device, which uses a vortex mixing filter for cell separation. There was no evidence of coagulopathy; mean free plasma haemoglobin levels were slightly raised ( I 7 mgldl) and plasma heparin concentration was negligible (0.10 unitslml) 4 h after surgery. A transient drop in plasma jibrinogen levels and the appearance of jibrin degradation products in low concentrations (mean 1.5 m g l l ) were seen. Oxyhaemoylobin dissociation curves showed the salvaged red blood cells to have a normal afinity for oxygen. Renal and hepatic function remained unaltered and there were no complications attributable to autotransfusion. The device was easy to handle and a trained operator was not required.
