[A case of excessive hemodilution due to ectopic pregnancy]

A 23-year-old female was admitted to our hospital due to hemorrhagic shock with hemoglobin concentration of 2.4 g.dl-1. A diagnosis of ectopic pregnancy was made and immediate emergency operation was performed with massive blood transfusion and rapid fluid infusion. The postoperative course was uneventful. The reasons for no apparent damage in major organs might be short duration of hemodilution, young age, being a female and immediate operation and blood transfusion.
