Blood substitutes Artificial oxygen carriers: perfluorocarbon emulsions
Perfluorocarbon emulsions are being clinically evaluated as artificial oxygen carriers to reduce allogeneic blood transfusions or to improve tissue oxygenation. Perfluorocarbon emulsions are efficacious in animal experiments, and in humans they are well tolerated and at least as successful to reverse physiologic transfusion triggers than autologous blood. Perfluorocarbon emulsions may be used i...
متن کاملComparison of Artificial Saliva Substitutes
Human saliva consists of water, glycoproteins, enzymes, antimicrobial substances and electrolytes. From biophysical point of view, saliva is a viscoelastic fluid with distinct surface activity. Commercial artificial saliva used in salivary gland disorders should resemble normal saliva in biophysical properties. In this study we evaluated the biophysical properties of saliva and existing saliva ...
متن کاملBlood substitutes
Blood substitutes have long been sought after, and artificial oxygen carriers may soon become a reality. Despite increased safety of allogeneic blood in terms of transmission of infectious diseases [1], avoiding allogeneic blood transfusions remains an important goal in perioperative and intensive care medicine. This is because allogeneic blood transfusions may cause immunosuppression with an i...
متن کاملBlood and blood substitutes.
Each year, in Europe, approximately seven million units of colloidal plasma substitutes are given to patients. Often they are used uncritically, which may account for the increased incidence of sideeffects which has been noted over the last decade. Their increasing use is understandable in view of the disadvantages of using blood; these include the difficulties in finding sufficient donors of a...
متن کاملPhysiological properties of blood substitutes.
Blood substitutes (modified hemoglobin solutions, perfluorocarbon emulsions) serve as artificial oxygen carriers and are alternatives to blood transfusions. Hemoglobin solutions mimic the sigmoidal oxygen dissociation curve of natural blood. Perfluorocarbon emulsions exhibit a linear relation between PO2 and dissolved oxygen. The most advanced substances may enter medicine in few years.
