Abstract :
Introduction: Blood is transfused to increase the oxygen carrying capacity and the intravas- cular volume. The requirement of blood transfusion is not simply dependent upon the haemoglobin or haematocrit values but the emphasis is also placed upon the age and health of the patient. The potential risks of blood transfusion have necessitated finding alternatives to allogeneic blood tran- sfusion. This study was conducted to determine the efficacy and safety of moderate acute normo- volemic hemodilution to reduce allogeneic red blood cells transfusion in operations in which blood transfusion was otherwise required. It is an interventional clinical trial. The study was carried out in the department of anaesthesia, operation theatre and intensive therapy care unit, Combined Military Hospital, Okara Cantt, during the period from January 2003 to October 2003. Materials and Methods: Twenty five patients of ASA-I and II status, who were undergoing elective surgical procedures, were subjected to the technique of moderate acute normovolaemic haemodilution. The intravascular volume of the patients was maintained with lactated Ringer’s solution and 6% hexaethyl starch solution. Autologous blood was reinfused after the operation. Results: All patients in this study remained haemodynamically stable. No patient required any homologous blood transfusion. Moderate ANH was found a useful, safe and economical technique. It can be used as an alternative technique in operations in which homologous blood is otherwise required.
