Outline of Final Research Achievements |
Tests reflecting fibrinogen in the blood (FIBTEM) did not change significantly 24 hours after acute normovolemic hemodilutional blood collection. Tests reflecting coagulation factors and platelet activity (EXTEM ) decreased in a time-dependent manner, but were all within normal limits. Acute normovolemic hemodilutional blood can be used for hemostatic purposes more than 8 hours after collection if stored at room temperature. In the future, it is necessary to clarify the clinical impact of acute normovolemic hemodilution on hemostasis in patients.

Academic Significance and Societal Importance of the Research Achievements |
希釈式自己血輸血は同種血輸血を回避する手段として実施される自己血輸血の一つである。本研究により8時間を超える長時間手術においても希釈式自己血輸血の凝固機能が維持されることがわかった。新型コロナ感染症の流行により同種血輸血の供給が不足する状況下において希釈式自己血輸血が手術中の凝固因子補充を目的として長時間使用できる可能性が示された。
