Blood transfusion Indirect

Indirect blood transfusion is a process in which the blood of a first donor is exchanged with the blood of a second donor. This is done in order to prevent possible incompatibility between donor and recipient blood and reduce the risk of complications such as thrombosis or transfusion shock.

The procedure of indirect blood transfusion is performed in several stages. The first procedure involves decompression (lowering pressure) of the first dose of donor blood and saturating it with heparin. Next, this blood is transferred to a second sensor, where the blood is saturated with oxygen, a proteolytic enzyme (to dissolve blood cells), and erythrocyte polyvalent erythrocytes (to maintain the venous blood volume). This blood is then directed through a high-permeability filter to remove cellular debris and injected into the recipient. Then transverse transfusion is carried out. Here, the blood from the vein of the indirect sensor of the first portion is injected into the second portion, and from there it is sent to the patient's vein. The total volume of blood transfused is then measured and indirect blood anticoagulation is administered. After a certain period of time, the total number of transfused volumes is re-measured and the patient's functional status after transfusion is checked. As an additional control, samples of donor blood are taken for clotting and absence of incompatibility. After the control pause, infusion solutions are administered along with the blood component: colloid (for example, albumin solution), crystalloid, glucose-salt, hormonal, antibiotics, plasma and others. With this method of primary exchange of blood components, an error may occur, since the resulting red blood cells and platelets have already been damaged by previous manipulations. But this error can be corrected by removing part of the blood from the second donation. You will have to wait a little (about 24 hours) until she restores her oxygenation. Additionally, this method can be expensive and require the use of multiple donors and blood components during the procedure. It is not recommended to use this method without sufficient experience and knowledge. However, indirect transfusion may be necessary in emergency situations when the patient's life is at risk and there are not sufficient supplies available.
