Fluosol-DA as a red-cell substitute in acute anemia.
The New England Journal of Medicine
|June 26, 1986
Summary
Fluosol-DA, a red-cell substitute, showed no benefit in moderate anemia and was ineffective in severe anemia for patients refusing transfusions. No adverse reactions were noted, but mortality was high in the severe anemia group.
Area of Science:
- Medical Science
- Hematology
- Anesthesiology
Background:
- Acute anemia management is critical, especially in patients refusing blood transfusions.
- Red-cell substitutes are explored as alternatives to allogeneic blood products.
Purpose of the Study:
- To evaluate the safety and efficacy of Fluosol-DA as a red-cell substitute in surgical patients with acute anemia who refused blood transfusions.
- To determine if Fluosol-DA can meet the physiological oxygen-carrying needs in anemic patients.
Main Methods:
- A study involving 23 surgical patients with acute blood loss and religious objections to transfusions.
- Fifteen moderately anemic patients did not receive Fluosol-DA; eight severely anemic patients received the drug up to a maximal dose.
- Assessed physiological need for oxygen, arterial oxygen content, and patient survival.
Main Results:
- No adverse reactions to Fluosol-DA were observed.
- Severely anemic patients receiving Fluosol-DA showed minimal increase in arterial oxygen content (0.7 +/- 0.1 ml/dL).
- Six of eight severely anemic patients (75%) died; 14 of 15 moderately anemic patients survived.
Conclusions:
- Fluosol-DA is unnecessary in moderate anemia and ineffective in severe anemia for patients refusing blood products.
- The limited efficacy may be due to small oxygen-carrying capacity increase, short half-life, and low total dose.
- High mortality in the severe anemia group receiving Fluosol-DA warrants caution.

Trigonometric substitution is a technique used to simplify integrals that contain square root expressions involving quadratic forms. It is particularly effective when the integrand includes terms resembling those found in standard geometric equations, such as circles or ellipses.Molniya satellites follow highly elliptical orbits, repeatedly sweeping out the same regions of space as they revolve around Earth. To estimate the area enclosed by such an orbit, the path is modeled as an ellipse...

Integrals involving non-rational functions are often difficult to evaluate using standard techniques, especially when radicals appear in the integrand. Rationalizing substitution provides a systematic method for simplifying such integrals by converting them into rational forms that are easier to handle.Consider a rod whose linear mass density depends on a constant linear density, a characteristic length, and the distance from the left end of the rod. Determining the total mass requires...

01:29Evaluating Limits by Direct Substitution
182
In the analysis of functions that represent continuous physical phenomena, it is often necessary to determine the output value as the input approaches a specific point. When a combination of algebraic terms defines the function and exhibits no discontinuities or abrupt changes near the point of interest, the limit of the function can be evaluated directly. This process, known as direct substitution, involves replacing the variable in the expression with the value it approaches.Direct...

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

01:19Diazonium Group Substitution: –OH and –H
3.4K
Nitrous acid, a weak acid, is prepared in situ via the reaction of sodium nitrite with a strong acid under cold conditions. This nitrous acid prepared in situ reacts with primary arylamines to form arenediazonium salts. Such reactions are known as diazotization reactions. As shown in Figure 1, the formation of arenediazonium salts begins with the decomposition of nitrous acid in an acidic solution to give nitrosonium ions.

This lesson discusses the stability of substituted cyclohexanes with a focus on energies of various conformers and the effect of 1,3-diaxial interactions.
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
