RecruitingPhase 2Biological interventionStudy of Acute Normovolemic Hemodilution (ANH) in People With Ovarian Cancer Who Are Having Cytoreductive SurgeryParticipants will be scheduled for primary cytoreductive surgery as part of their standard care. Before surgery, participants will be assigned by chance to a study group. Depending on which group they are in, they will receive either acute normovolemic hemodilution/ANH during surgery or standard surgical management during surgery. The researchers think acute normovolemic hemodilution/ANH may decrease the need for allogenic blood transfusion/ABT in people having primary cytoreductive surgery.
