Because of complications such as viral infection and graft-versus-host disease, we have made every effort to avoid homologous transfusion at Osaka National Hospital. We utilize autologous transfusion and induce hypotensive anesthesia to reduce homologous transfusion in elective surgery.We investigated the effect of prostaglandin E1 (PGE1) on hemolysis in intraoperative blood-salvaging autotransfusion. Twenty-two patients (ASA 1-2) who were anesthetized with modified NLA and in whom primary total hip replacement was performed were randomly allocated to one of two groups. Ten patients were given induced hypotensive anesthesia with PGE1 (PG group) and twelve patients isoflurane (ISO group).Free-hemoglobin concentrations in salvaged blood and waste rinse fluid were measured, and the hemolysis rate during the blood-salvaging process was calculated.The concentration of free hemoglobin in reinfused blood and waste rinse fluid was lower in the PG group than in the ISO group. These findings suggest that less hemolysis occurred in the PG group, resulting in a higher salvage rate.These results suggest that induced hypotensive anesthesia with PGE1 reduces hemolysis in intraoperative blood-salvaging autotransfusion.
