Objective To evaluate the blood-saving efficacy of acute hypervolemic hemodilution (AHH)-hemostatics-intraoperative blood salvage (IOBS) in patients undergoing orthopedic surgery. Methods One hundred and twenty ASA Ⅰ or Ⅱ patients of both sexes, aged 18-64 yr, scheduled for elective orthopedic surgery under general anesthesia with an expected blood loss of 800 ml or more, were randomly divided into 4 groups ( n = 30 each) : AHH + IOBS + hemostatics group; IOBS + hemostatics group; AHH + IOBS group; AHH + bemostatics group. AHH was induced with 6% hydroxyethyl starch 130/0.4 15 ml/kg infused iv at a rate of 40 ml/min immediately after tracheal intubation until the time of immediately before skin incision, IOBS was performed immediately before skin incision. Intravenous hemocoagulase 2 kU and im hemocoagulase 1 kU were injected 10 min before skin incision. The total volume of fluid intake and output, HR, MAP and CVP were recorded during the operation. Vein blood samples were taken for determination of Hb, Hct, platelet counts (Plt), prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen concentration (Fib) .Results CVP was significantly lower in IOBS+ hemostatics group than in AHH + IOBS + hemestaties group ( P < 0.05), while no significant difference in CVP was found between AHH + IOBS and AHH + IOBS + hemostatics group and between AHH + hemostatics and AHH +IOBS + hemostaties group (P > 0.05). The volume of blood loss was significantly higher in AHH + IOBS group, and the allogenic blood transfusion volume was significantly higher, while the percentage of the patients without allogeneie blood transfusion and without FFP transfusion lower in AHH + hemostatics group than in AHH + IOBS + hemostatics group ( P < 0.05 or 0.01 ), but there were no significant differences in the above parameters between IOBS + hemostatics group and AHH + IOBS + hemostatics group ( P > 0.05). Hb, Hct, Plt and Fib were significantly higher in IOBS + hemostatics group than in AHH + IOBS + hemostafics group( P < 0.05), but there were no significant differences in the above parameters between AHH + IOBS and AHH +IOBS + hemostatics group and between AHH + hemostatics and AHH + IOBS + hemestatlcs group (P > 0.05 ). Conclusion The blood-saving efficacy of AHH-bemostatics-IOBS is good in patients undergoing orthopedic surgery and it is a safe technique.
