Area of Science:

  • Biomedical Engineering
  • Hematology
  • Sports Science

Background:

  • The development of artificial substitutes for damaged body parts has a long history.
  • Artificial red blood cell substitutes remain elusive despite ongoing research.
  • Donor blood shortages and transfusion risks drive the need for alternatives.

Purpose of the Study:

  • To explore various approaches in developing artificial oxygen carriers as blood substitutes.
  • To discuss the potential clinical applications of blood substitutes.
  • To address the emerging concern of artificial oxygen carrier misuse in sports.

Main Methods:

  • Investigating modified hemoglobin solutions and perfluorocarbon emulsions.
  • Developing artificial red blood cells by encapsulating hemoglobin in liposomes.

  • Stabilizing hemoglobin to improve its properties for re-infusion.

    • Main Results:

    • Modified hemoglobin and perfluorocarbons show promise as oxygen carriers.
    • Artificial red blood cells aim to mimic natural cell function.
    • Blood substitutes have diverse potential clinical applications, including surgery and organ preservation.

    Conclusions:

    • Artificial oxygen carriers offer potential solutions for blood shortages and specific medical needs.
    • The lack of detection methods for artificial oxygen carriers poses a risk for exploitation in sports.
    • Further research is needed to develop reliable testing methodologies.
