This study shows that using intraoperative cell salvage and autotransfusion significantly reduces the need for bank blood in patients undergoing elective valve surgery. Most patients required no transfusions, minimizing risks associated with allogeneic blood.

Area of Science:

  • Cardiovascular Surgery
  • Transfusion Medicine
  • Anesthesiology

Background:

  • Elective valve surgery often necessitates blood transfusions, increasing risks and costs.
  • Optimizing blood management strategies is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate the effectiveness of intraoperative cell salvage and autotransfusion in reducing allogeneic blood use.
  • To assess blood utilization patterns in patients undergoing rheumatic valve surgery.

Main Methods:

  • Prospective study of 40 patients with rheumatic valvular lesions undergoing elective valve surgery.
  • Utilized intraoperative cell salvage for discard suction and pump oxygenator blood.
  • Accepted normovolemic anemia in stable patients.

Main Results:

  • 80% of patients (32/40) received no bank blood or blood products.
  • Only 12 units of whole blood were transfused in 8 patients.
  • Mean reinfused volume via cell saver was 365.12 ml.

Conclusions:

  • Intraoperative cell salvage is highly effective in minimizing allogeneic blood transfusion in elective valve surgery.
  • This approach significantly reduces the reliance on donor blood, enhancing patient safety.
