Summary

This study demonstrates that combining preoperative autologous blood collection, acute normovolemic hemodilution, controlled hypotension, and intraoperative cell salvage significantly reduces homologous blood use in spinal surgery. These methods are safe and effective for managing blood loss during complex procedures.

Area of Science:

  • Anesthesiology
  • Surgical Oncology
  • Transfusion Medicine

Context:

  • Extensive spondylosurgical operations pose significant risks of blood loss.
  • Managing perioperative blood loss is crucial for patient outcomes.
  • Traditional methods may not sufficiently minimize homologous blood transfusion requirements.

Purpose:

  • To evaluate the efficacy of a combined anesthetic and surgical strategy in reducing homologous blood consumption during complex spinal surgeries.
  • To assess the safety and impact of these methods on patient recovery.

Summary:

  • Sixty-six patients undergoing extensive spondylosurgery received a combination of anesthetic techniques, including preoperative autologous blood collection (in 6 patients), acute normovolemic hemodilution (in 45 patients), controlled hypotension using sodium nitroprusside (MAP 8-9 kPa), and intraoperative cell salvage (Dideco Stat, >50% yield).

  • This multimodal approach significantly reduced homologous blood requirements: 90 ml intraoperatively, 300 ml on postoperative day 1, and 120 ml on postoperative day 2.
  • No complications were recorded during or after intraoperative cell salvage. Postoperative anemia, while present, did not compromise patient recovery.

    • Impact:

    • Demonstrates a successful strategy for minimizing allogeneic blood transfusions in high-risk spinal surgery.
    • Highlights the potential for significant reductions in blood product usage and associated costs.
    • Identifies a potential complication of increased postoperative leucocyte count (19.7 x 10^9/L) due to cell salvage, suggesting the need for modified salvage programs to prevent potential Acute Respiratory Distress Syndrome (ARDS).
