[Alternatives to allogenous blood transfusion]

Area of Science:

• Transfusion Medicine
• Surgical Hemostasis

Context:

• Allogeneic blood transfusions carry inherent risks.
• Minimizing transfusion-related complications is crucial in surgery.

Purpose:

• To review autologous blood transfusion techniques and alternatives to allogeneic transfusion.
• To highlight methods for reducing transfusion risks and improving patient outcomes.

Summary:

• Autologous blood transfusion techniques, including preoperatory donation, acute normovolemic hemodilution, and intra/postoperative blood salvage, mitigate risks of allogeneic transfusions.
• These methods are suitable for planned surgeries with significant blood loss and often involve erythropoietin and iron therapy.
• Artificial oxygen transporters, such as hemoglobin and perfluorocarbon solutions, present an alternative with benefits like no cross-matching and easy storage, despite minor toxicity concerns.

Impact:

• Autologous techniques enhance patient safety by reducing exposure to allogeneic blood.
• Artificial oxygen carriers offer promising alternatives for emergency and remote settings.
• Improved blood management strategies contribute to lower morbidity and mortality rates in surgical patients.
