Modified hemoglobin shows the most promise as a blood substitute, advancing toward clinical use. Research into these oxygen carriers offers new physiological insights and challenges current understanding of oxygen delivery.

Area of Science:

  • Biomedical Engineering
  • Physiology
  • Materials Science

Background:

  • Blood substitutes are crucial for medical applications, with perfluorocarbons, modified hemoglobins, and liposome-encapsulated hemoglobin being key candidates.
  • Hemoglobin-based oxygen carriers (HBOCs) have shown the most significant progress.
  • Hemoglobin's high activity necessitates modification to mitigate potential adverse effects.

Purpose of the Study:

  • To review the progress and challenges in developing hemoglobin-based oxygen carriers as blood substitutes.
  • To highlight the insights gained into oxygen delivery and physiological processes through the study of these molecules.

Main Methods:

  • Review of existing literature on perfluorocarbons, modified hemoglobins, and liposome-encapsulated hemoglobin.

  • Analysis of the progress toward clinical application of hemoglobin-based oxygen carriers.
  • Examination of the physiological challenges and insights related to oxygen transport.

    • Main Results:

    • Hemoglobin-based oxygen carriers represent the most advanced class of blood substitute candidates.
    • Significant progress has been made, but clinical translation faces challenges.
    • Development has spurred new understanding of fundamental physiological processes.

    Conclusions:

    • Modified hemoglobins are leading candidates for blood substitute development.
    • Further research is essential to overcome challenges in clinical application.
    • The study of HBOCs has yielded valuable insights into oxygen delivery and utilization.
