Brief Summary

The prevention of perioperative anemia has the potential to reduce complications, hospital stays, and long-term prognosis in patients undergoing bone tumor surgery. Data from previous studies suggest that the clinical efficacy of acute normovolemic hemodilution (ANH) has always been controversial, and intraoperative fluid administration strategy is an important confounding factor. The HEAL trial will assess whether ANH will improve postoperative hemoglobin levels when applying goal-directed fluid therapy in patients undergoing bone tumor surgery.

Conditions

Bone Tumor; Acute Normovolemic Hemodilution; Goal-Directed Fluid Therapy

Outcome Measures

Primary Outcomes (1)

• Hemoglobin concentration on the first day after surgery

  The concentration of hemoglobin on the first day after surgery

  The first day after surgery

Secondary Outcomes (7)

• The rate of perioperative transfusion of allogeneic blood products

  From the start of surgery to discharge or the 7th day following the operation, which comes first

• The blood loss during the perioperative period

  From the start of surgery to discharge or the 7th day following the operation, which comes first

• The volume of fluid administration during the intraoperative period

  From the beginning to the end of the surgery

• The coagulation function tests during the perioperative period

  From the start of surgery to discharge or the 7th day following the operation, which comes first

• Perioperative embolic events

  From the start of surgery to discharge or the 7th day following the operation, which comes first

Study Arms (2)

acute normovolemic hemodilution group (ANH group)

EXPERIMENTAL

The ANH process was initiated after tracheal intubation. After completion of ANH, goal-directed fluid therapy will begin until the end of the surgery.

Procedure: acute normovolemic hemodilution

Standard Group (STD group)

NO INTERVENTION

After tracheal intubation, goal-directed fluid therapy will be implemented until the end of the surgery.

Interventions

acute normovolemic hemodilution PROCEDURE

The ANH was conducted with more than 8 ml/kg of whole blood drawn from an internal jugular introducer by gravity and collected into standard sterile blood storage bags containing citrate phosphate-dextrose anticoagulant. The allowable blood loss was capped according to the preoperative hemoglobin, estimated blood volume, and the target hemoglobin (10 g/dL). The collected blood was simultaneously replaced by an equal volume of succinyl gelatin solution via at least one large bore peripheralvenous catheter to maintain hemodynamic stability.
