Scientists have developed artificial blood that can be transfused into patients with any blood group and stored more than a year.
A significant loss of platelets, which stop bleeding, and red blood cells, which deliver oxygen to the cells, lead to the death of a person. Although in special conditions platelets can be stored for 4 days, and erythrocytes for up to 20 days, it is still necessary to know the patient's blood group in order to transfuse donor blood, which is problematic in emergency situations.
However, a team of researchers from Japan's National Defense College of Medicine claims to have created artificial blood made of platelets and red blood cells, each component of which is contained in a tiny package known as a liposome, made from a cell membrane. Thanks to this feature it can be stored for over a year at room temperature.
Tests showed that out of 10 rabbits suffering from severe blood loss, transfusions saved six, which is comparable to the use of real blood. The researchers also reported that no negative side effects such as blood clotting occurred..
Since the developed artificial blood can be transfused without confirming the patient's blood group, it can be used for emergency medical care right on the spot, which will save more lives..
Medicine is developing at a rapid pace and new technologies play an important role in this process.
