Brief 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. However, in all the guidelines, the determination of whether RBCs should be administered when the hemoglobin level is in the range of 7\~10g/dL is based on the judgment from anesthesiologists or surgeons. Index of transfusion trigger for patients with hemoglobin level between 7/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 7/dL and 10g/dL could be calculated by their history about heart and blood pressure, and routine monitoring parameters including pulse oximetry, temperature, and the use of vasoactive medications. To verify this hypothesis, the investigators present West China Perioperative Transfusion Score (WCPTS) 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.

Study Arms (2)

Hemoglobin level based on WCPTS

EXPERIMENTAL

According to WCPTS, the patient's hemoglobin level will be maintained not less than 7,8,9,or 10g/dL. Determination of whether a patient need red blood cells transfusion is based on WCPT Score.

Other: Transfusion trigger based on WCPTS

Hemoglobin level 10g/dL

ACTIVE COMPARATOR

The patient's hemoglobin level is maintained not less than 10g/dL perioperatively.

Other: Maintenance of hemoglobin level not less than 10g/dL

Interventions

The patient's hemoglobin level is maintained not less than 10g/dL perioperatively.

Hemoglobin level 10g/dL

Determination of whether a patient needs red blood cell transfusion or which hemoglobin level should be maintained is based on WCPTS
