[Preoperative autotransfusion and hemodilution and its value in reconstructive vascular surgery]

Autotransfusion and haemodilution are the most safe and well known methods of blood protection in patients planned for vascular operations. During reconstructive vascular surgery autotransfusion with hypovolemic or normovolemic haemodilution were used. In the I group of patients hypovolemic haemodilution was done. In the II group of patients vascular bed was filed up with Ringer solution or with 6% solution of hydroxyethyl starch. The type of haemodilution and its influence on haemodynamics were estimated. Investigations were done by echocardiograph: ATL ULTRAMARK 8. It was concluded that the most effective are autotransfusion and normovolemic haemodilution with filing up vascular bed with Ringer solution.
