Summary
Artificial blood substitutes like Fluosol-DA physically dissolve oxygen. While generally safe, potential pulmonary reactions can be managed with steroids, enabling clinical use.
Area of Science:
- Biomedical Engineering
- Hematology
- Pharmacology
Background:
- Development of artificial blood substitutes is ongoing.
- Perfluorocarbon emulsions, such as Fluosol-DA, are being investigated for oxygen transport.
- Unlike hemoglobin, perfluorocarbons physically dissolve oxygen.
Purpose of the Study:
- To evaluate the oxygen-carrying capacity and safety of Fluosol-DA.
- To explore potential adverse reactions and their management.
- To identify novel applications for perfluorocarbon emulsions.
Main Methods:
- Clinical trials were conducted to assess Fluosol-DA's efficacy and safety.
- Oxygen transport capabilities were measured under varying oxygen atmospheres.
- Pulmonary reactions were analyzed, and preventative measures were investigated.
Main Results:
- Fluosol-DA demonstrates clinically useful oxygen transport with supplemental oxygen.
- Japanese clinical trials indicate transfusion safety.
- Significant pulmonary reactions, linked to complement activation, can be mitigated by steroid administration.
Conclusions:
- Fluosol-DA shows promise as an oxygen carrier, particularly in critical care settings.
- Steroid prophylaxis is recommended to prevent Fluosol-DA-induced pulmonary reactions.
- Perfluorocarbon emulsions have diverse applications, including resuscitation and treatment of conditions like carbon monoxide poisoning.
