    Abstract:
    Clinical testing of perfluorocarbons (PFC) as blood substitutes began in the early 1980's in the form of Fluosol DA-20% (FDA), a mixture of perfluorodecalin and perfluorotripropylamine emulsified with Pluronic F68. We have treated 55 patients (Treatment (T) = 40; Control (C) = 15) with intravenous infusions of 30 cc/kg of FDA as part of either a randomized, clinical trial or a humanitarian protocol. All patients were Jehovah's Witnesses who refused blood transfusion and were severely anemic (mean hemoglobin = 4.6 g/d). FDA successfully increased dissolved or plasma oxygen content (P1O2 in ml/dl), but not overall oxygen content (T group: P1O2 baseline = 1.01 +/- .27, P1O2 12hrs = 1.58 +/- .47 [p = < .0001, t-test]; P1O2 12 hrs: T = 1.58 +/- .47, C = 1.00 +/- .31, p = < .0002, t-test). This effect persisted for only 12 hours post infusion, and had no apparent effect on survival. FDA is an ineffective blood substitute because of low concentration and short half-life. Improved emulsion design may resolve these problems, thereby producing a more effective agent. Our discussion will include a review of our data plus a summary of other reports of FDA efficacy as a blood substitute.
