Blood transfusion Intra-arterial

Intra-arterial blood transfusion: what is it and how is it performed?

Intraarterial blood transfusion is a method of blood transfusion in which blood is directly injected into an artery, bypassing the pulmonary circulation. This method is used in critical situations when it is necessary to quickly and effectively restore blood flow and provide the body with oxygen and nutrients.

The first mention of intra-arterial blood transfusion dates back to 1929, when the French physician André Janssens used this method to treat cerebral hemorrhages. Since then, this method has found wide application not only in neurology, but also in cardiology, oncology and other areas of medicine.

The main advantage of intra-arterial blood transfusion is the ability to quickly and accurately deliver blood to the desired point in the body, bypassing the pulmonary circulation. This allows you to achieve the maximum effect of blood transfusion with minimal loss of time.

However, transfusion of blood into an artery is a procedure that requires certain skills and training on the part of medical personnel. In this case, it is necessary to monitor the pressure and rate of infusion to avoid the development of complications such as thrombosis, embolism, bleeding and others.

It is important to note that intra-arterial blood transfusion is a little-studied method and its use is limited only in critical cases and with strict medical indications.

In conclusion, intra-arterial blood transfusion is a method that can save lives in critical situations when it is necessary to quickly and effectively restore blood flow and provide the body with oxygen and nutrients. However, its use requires certain skills and training of medical personnel, as well as strict medical indications and control over the process.

Intravenous blood transfusion is the process of transfusing blood from a donor to a recipient using intravenous (injection) administration. Today, the most popular method of this transfusion is the infusion of blood components through one or more veins of one limb into other veins. The transfusion rate is maintained at 250–300 ml/min, but faster transcatheral transfusion is possible, provided that the bloodstream is first cleared of gas.

Depending on the amount of blood component administered, single-component, two- and three-volume transfusions are distinguished. As a rule, it does not exceed 3 blood volumes, which allows intoxication to be kept to a minimum. The transfused blood may contain only components that exclude vaccination or the action of certain medications, or are used orally. When performing indirect transfusions, drugs from donor blood can be used. Intravenous transfusion through a catheter is usually accompanied by rapid replacement. After transfusion, the patient's condition should be carefully monitored.
