Summary

This study is aimed to determine if acute normovolemic hemodilution (ANH), an established blood conservation technique, reduces the requirement for allogeneic blood transfusion in operations with prediction of surgical bleeding over 20% of estimated blood volume (EBV)

Detailed description

Allogeneic blood transfusion is often done during surgery to save life- threatening conditions. Blood conservation is a method that can reduce peri-operative allogeneic blood transfusion. This study has been conducted on 34 patients underwent laparotomy surgery with bleeding more than 20% of EBV. After being informed concent, research subjects were randomized into two groups: ANH (conducted ANH) and control group (without ANH). After starting general anesthesia, the ANH group was withdrawing blood based on Gross formula. Restoration of circulated volume was instituted by infusion of colloids. In control group, the operation was started right after the induction of anesthesia. The monitoring of blood pressure, heart rate, the amount of bleeding, total fluid, urine production, hemoglobin concentration and number of allogenic transfusion were recorded.

Interventions

Type	Name	Description
PROCEDURE	ANH	After general anesthesia is applied, blood was taken through the cubital vein and collected into standard blood bags containing CPDA anti-coagulant. The blood obtained is then stored at temperature of 23 - 25 Celsius degree and given back to patients in the operating room after the bleeding stopped and as soon as there are indications of transfusion.
