術前貧血に対するスクロソミアル鉄剤と静脈内鉄剤の比較 (RSIVI)
術前貧血に対するスクロソーム鉄剤と静脈内鉄剤のランダム化比較試験 (RSIVI)
50 patients with anemia scheduled for heart surgery or procedures will be randomized to receive either oral sucrosomial iron or standard-of-care intravenous iron before surgery to see if the oral iron is as effective as intravenous iron in increasing the red blood cell count.
調査の概要
状態
詳細な説明
Participants will be randomly assigned in a 1 to 1 ratio to one of two treatment groups. One group will receive intravenous (IV) iron, and the other group will receive oral sucrosomial iron.
Participants assigned to the IV iron group will receive two infusions at the University of Rochester Medical Center Center for Perioperative Medicine. Intravenous iron will be administered through a small plastic tube placed into a vein. Saline may be used to maintain the IV line as needed.
Participants assigned to the oral sucrosomial iron group will receive capsules to take at home until the date of surgery, with a dosage of two capsules per day.
All other aspects of perioperative care will follow standard practice. A blood sample for complete blood count and iron studies will be obtained on the day of surgery. This is typically collected when the IV is placed, so an additional needle stick is usually not required.
Randomization applies only to the two treatment arms (intravenous iron and oral sucrosomial iron). The third arm is a non randomized observational cohort for data collection only.

介入・治療 |
|---|---|
|
アクティブコンパレータ：intravenous (IV) iron
If a participant is to receive IV iron, they will be scheduled to have two infusions, at the URMC Center for Perioperative Medicine (CPM). They will receive the iron through an IV, which is a small plastic tube inserted into a vein in the arm using a needle. This may require that saline water be inserted into the tube to keep the tube from clogging. |
2 infusions of intravenous iron (ferumoxytol) |
|
実験的：Sucrosomial Iron
If a participant is to receive oral iron capsules, they will be provided with enough capsules to last until the date of surgery and will take 2 capsules every day. |
blood draw on the day of surgery to check hemoglobin and red blood cell count and iron studies |
|
介入なし：3rd arm is for data collection only
In addition, 25 patients refusing randomization, but accepting data collection, will be treated as per the standard of care, but will have data collected as for the randomized groups with the exception of no CBC or iron studies will be performed on the day of surgery unless as part of routine care unrelated to study participation. |

|
Change in hemoglobin from baseline to day of surgery or procedure
時間枠：From the pre operative visit to the day of surgery or procedure, up to approximately eight weeks
|
Change in hemoglobin in grams per deciliter from the baseline pre operative complete blood count to the complete blood count obtained on the day of surgery or procedure. Change will be calculated as hemoglobin on the day of surgery minus baseline hemoglobin. |
From the pre operative visit to the day of surgery or procedure, up to approximately eight weeks
