Trial summary

Guidelines for blood transfusion have been issued for years. According to these guidelines, red blood cells (RBCs) transfusion should be given when the hemoglobin level is less than 6g/dL or 7g/dL and is unnecessary when the level is more than 10g/dL. Read more about this study

About this study

Guidelines for blood transfusion have been issued for years. According to these guidelines, red blood cells (RBCs) transfusion should be given when the hemoglobin level is less than 6g/dL or 7g/dL and is unnecessary when the level is more than 10g/dL. However, in all the guidelines, the determination of whether RBCs should be administered when the hemoglobin level is in the range of 6~10g/dL is based on the judgment from doctors. Index of transfusion trigger for patients with hemoglobin level between 6g/dL and 10g/dL is necessary and important in clinical practice.

Based on the aim of blood transfusion that maintain the balance of oxygen supply and oxygen consumption, the investigators hypothesize that index of transfusion trigger for patients with hemoglobin level between 6g/dL and 10g/dL could be calculated by parameters including infusion rate of inotropic drugs for maintaining normal cardiac output, fraction of inspired oxygen, core temperature, and torlerance to anemia. To verify this hypothesis, the investigators present West China Transfusion Score for Critically-ill Patients(WCTS-CP) for the trigger of transfusion according to the patient's history and monitoring parameters, and the investigators design a randomized controlled clinical trial to test this score.

Read the detailed description

Anemia is a common phenomenon in critically ill patients, and blood transfusion may provide guarantee for oxygen delivery. On the other hand, blood transfusion is associated with many risks including hemolytic and nonhemolytic reactions, transfusion related acute lung injury (TRALI), and others. Besides, blood is insufficient worldwide. How to eliminate allogeneic blood transfusion is an important part in clinical practice.

Guidelines for blood transfusion have been issued for years. According to these guidelines, red blood cells (RBCs) transfusion should be given when the hemoglobin level is less than 6g/dL or 7g/dL and is unnecessary when the level is more than 10g/dL. However, in all the guidelines, the determination of whether RBCs should be administered when the hemoglobin level is in the range of 6~10g/dL is based on the judgment from specific doctors. Index of transfusion trigger for critically ill patients with hemoglobin level between 6g/dL and 10g/dL is necessary and important in clinical practice.

Based on the aim of blood transfusion that maintain the balance of oxygen supply and oxygen consumption, the investigators hypothesize that index of transfusion trigger for patients with hemoglobin level between 6g/dL and 10g/dL could be calculated by parameters including infusion rate of inotropic drugs for maintaining normal cardiac output, fraction of inspired oxygen for maintaining saturation of oxygen≧95%, core temperature, and torlerance to anemia.

The investigators set down the West China Transfusion Score for Critically-ill Patients(WCTS-CP) ,the initial score is 6. If a patient's cardiac output is normal without infusion of inotropic drugs, the heartbeat less than 100 per minute,his saturation of oxygen could be maintained more than 95%, his core temperature is less than 38℃, and he has no history of ischemic cardiovascular disease , and he is below 55 of age,his score is 6.

If a patient has one or more problems, his score should be added 1 point for each problem.

The initial WCTS-CP score is 6, and the patient's score is calculated by the sum of each item.

Score 6:The transfusion trigger is 6g/dL, and the the patient's Hemoglobin level should be maintained not less than 6g/dL.

Score 7:The transfusion trigger is 7g/dL, and the the patient's Hemoglobin level should be maintained not less than 7g/dL.

Score 8:The transfusion trigger is 8g/dL, and the the patient's Hemoglobin level should be maintained not less than 8g/dL.

Score 9:The transfusion trigger is 9g/dL, and the the patient's Hemoglobin level should be maintained not less than 9g/dL.

Score 10 or >10:The transfusion trigger is 10g/dL, and the the patient's Hemoglobin level should be maintained not less than 10g/dL.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing RBC transfusion based on different protocols in people with Transfusion Related Complication and Critical Illness, run by West China Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jin Liu, M.D (18980601539), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of death and serious complications (time frame: 28 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 May 2014.
