Effect of blood volume management during bone tumor surgery

The Effect of Acute Normovolemic Hemodilution on Intraoperative Allogeneic Transfusion in Bone Tumor Surgery: a Prospective, Randomized Controlled Trial

Not applicable Interventional Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT06459141

This study is testing if a method called acute normovolemic hemodilution can help reduce the need for blood transfusions during bone tumor surgeries for patients aged 18 to 75.

What this trial studies

This trial investigates the impact of acute normovolemic hemodilution (ANH) on reducing the need for blood transfusions during bone tumor surgeries. It aims to determine if ANH, when combined with goal-directed fluid therapy, can minimize intraoperative allogeneic red blood cell transfusions, which are associated with increased postoperative complications. The study will involve patients aged 18 to 75 undergoing elective bone tumor resection, assessing blood loss and transfusion requirements. By evaluating the efficacy of ANH in this context, the trial seeks to improve patient outcomes and reduce the risks associated with blood transfusions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 who are scheduled for elective bone tumor resection surgery with a preoperative hemoglobin level of at least 11 g/dL.

Not a fit: Patients with conditions such as cardiopulmonary insufficiency, hepatic and renal dysfunction, or those undergoing palliative operations may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the need for blood transfusions and improve recovery outcomes for patients undergoing bone tumor surgery.

How similar studies have performed: While the efficacy of acute normovolemic hemodilution has been controversial, this study aims to clarify its role in a specific surgical context, making it a novel approach.
