Physicians offer new solution for blood transfusions

12.11.2002


The successful transfusion of a cell-free blood product on a 14-year-old Jehovah’s Witness may offer a solution for patients opposed to blood transfusions due to religious or personal beliefs.



"This was the first successful use of a human cell-free hemoglobin solution in a pediatric patient to manage life-threatening anemia due to an autoimmune disease," says Dr. Brian Kavanagh, professor of medicine at the University of Toronto and staff physician in critical care medicine at The Hospital for Sick Children. The patient suffered from immune thrombocytopenia, a condition that attacks platelets in the body. Platelets are present in blood and help blood clot; if platelet counts are very low, minor injuries or trauma can become very serious if the patient continues to bleed.

Kavanagh and colleagues Drs. Johann Hitzler and Natalie Anton treated the patient last year after she entered the hospital’s emergency room for a nosebleed that did not stop. Instead of a blood transfusion, they used a biochemically manufactured solution that contains hemoglobin but does not contain red blood cells. The solution has been used in adults but never for a child in this kind of situation, Kavanagh says.


While more study needs to be done with pediatric patients, Kavanagh says this cell-free hemoglobin is a viable alternative for Jehovah’s Witnesses. "Most current blood replacement options are fluids, plasma and other types of liquids that provide volume for blood but don’t provide the oxygen-carrying capacity. This solution provides oxygen-carrying capacity in exactly the same way that blood cells in hemoglobin do. That’s the crux of the matter. Still, only careful study will fully determine the balance of benefits and risk."

Kavanagh and colleagues reported this case in a fall issue of the British Journal of Haematology.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
