Comparing blood transfusion levels during and after surgery
Part of Blood & lymphatic clinical trials.
This trial tests whether giving blood transfusions sooner or later during surgery affects recovery for patients with low hemoglobin. It compares using a liberal (higher) threshold to give blood versus a more restrictive (lower) threshold.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You are having elective or urgent surgery (not emergency for major bleeding).
- Your hemoglobin (a part of your blood that carries oxygen) is low (less than 130 g/L) before surgery.
- During surgery, your hemoglobin drops to 100 g/L or lower.
- You have not had a heart attack or unstable chest pain in the last 6 weeks, and you are not having heart surgery or a liver transplant.

This study tests whether giving blood transfusions based on each patient's needs during and after heart surgery is safe and effective. It compares different transfusion thresholds to see which works better.
This study looks at how managing blood products during heart surgery with a heart-lung machine affects the risk of red blood cell breakdown in children. The goal is to find safer ways to handle blood during these procedures.
This study compares two different blood transfusion strategies during major surgery to see which is safer and more effective. If you are having major surgery and might need a blood transfusion, this trial could help guide how your doctors manage your blood levels.
This study looks at ways to reduce the need for blood transfusions during major liver surgery. It uses a technique to carefully manage blood loss, which may help you avoid needing donor blood.
This study tests a new way to manage blood during surgery, which may reduce the need for donor blood transfusions. It compares standard care with a method that uses your own blood and a special device to monitor your blood flow.
This study looks at how much donated blood (blood products) is needed for younger adults during heart surgery that uses a heart-lung machine. It may help doctors choose safer, more appropriate blood-saving plans for people like you.
