Blood circulation Extracorporeal (Cardiopulmonary Bypass)
Extracorporeal circulation (Cardiopulmonary Bypass) is one of the key technologies used in cardiac surgery to replace the work of the heart during operations. This technology allows the patient's heart and lungs to be temporarily stopped so that the surgeon can perform surgery. During this process, the functions of the heart and lungs are temporarily replaced by a pump oxygenator, also known as a cardiopulmonary machine.
The Extracorporeal Circulation procedure begins with the administration of anesthesia and preparation of the patient for surgery. The surgeon then makes an incision in the chest to gain access to the heart. After this, cannulas are put on the patient, which serve to connect him to the cardiopulmonary machine. One cannula is inserted into the left atrium, and the other into the aorta. A cannula inserted into the atrium allows blood to be pumped out of the heart into a machine where it passes through a special filter and oxygenator, where the blood is saturated with oxygen and cleared of carbon dioxide. The blood is then returned to the patient's body through a cannula inserted into the aorta.
The cardiopulmonary machine also monitors pressure, temperature and blood composition to maintain the patient's vital functions during surgery. Once the operation is completed, the cannulas are removed and the circulation returns to its natural state.
Extracorporeal circulation is a complex and technologically advanced procedure that allows cardiac surgeons to perform operations that were previously impossible. However, like any other operation, it is not without risks. Potential complications include bleeding, infection, and problems with lung and kidney function. Therefore, cardiac surgeons and anesthesiologists must be highly qualified and have extensive experience in operating the cardiopulmonary machine.
In conclusion, extracorporeal circulation is a key technology in cardiac surgery. It allows you to perform complex operations on the heart and lungs that were previously impossible. However, it is important to remember that this is a complex procedure and patients should only receive treatment from highly trained professionals who have sufficient experience in operating the cardiopulmonary machine.
Extracorporeal Circulation (Cardiopulmonary Bypass): The Art of Sustaining Life
In modern cardiac surgery, one of the key procedures is heart replacement, which is performed using a heart-lung machine known as extracorporeal circulation (Cardiopulmonary Bypass). This technique allows you to temporarily stop the patient’s heart during surgery and ensure his vital functions until normal blood circulation is restored. During this procedure, the functions of the heart and lungs are performed by a special device called an oxygenator pump.
Extracorporeal circulation is a complex and carefully tuned system designed to keep a patient alive during cardiac surgery. The procedure begins by inserting cannulas into the patient's major arteries and veins. The cannulas are designed to connect blood to an oxygenator pump, which replaces the functions of the heart and lungs. Blood leaves the patient's body through venous cannulas, passes through an oxygenator pump, where it is saturated with oxygen and metabolic waste products are removed, and then returns back to the body through arterial cannulas.
The patient's condition is carefully monitored throughout the operation. Special sensors monitor pressure, temperature and blood composition, which allows medical staff to adjust the parameters of the oxygenator pump according to the patient's needs. In addition, the patient may be given additional support throughout the procedure with medications and devices to maintain stability of his condition.
One of the main advantages of extracorporeal circulation is the ability to perform complex cardiovascular operations that require complete cardiac arrest. During the operation, the surgeon has the opportunity to work in a safe environment, controlling every step of the procedure. In addition, extracorporeal circulation significantly reduces the risk of blood loss and allows for more accurate surgery.
However, despite all the benefits, extracorporeal circulation is not without certain risks. Complications associated with the use of an oxygenator pump may occur during the procedure, including thromboembolic events, hemodynamic compromise, and systemic inflammatory reactions. In addition, the process of artificial circulation itself can lead to temporary disruptions in the functioning of some organs and systems of the body.
In recent years, research and development of new technologies and methods have been carried out aimed at improving the process of extracorporeal circulation and reducing the risks associated with it. The introduction of more advanced pump-oxygenation systems, the use of safer materials and blood contact surfaces, and improved methods of monitoring and regulating circulatory parameters all contribute to increasing the safety and effectiveness of the procedure.
In addition to cardiac surgery, extracorporeal circulation also finds application in other areas of medicine. For example, in resuscitation and treatment of severe pulmonary insufficiency can be used methodically
Extracorporeal blood circulation or, as it is also called, artardiopulmonary blood shunting is a surgical operation that consists of creating an alternative path for blood, bypassing the heart. This procedure is called Extracorporeal circulation.
Extracorporeal circulation is performed when the heart arteries cannot pass due to obstruction or damage and must be bypassed. This allows the heart-lung machine to perform the functions of the heart and lung instead of the patient.
Circulation occurs by replacing the disabled organ with blood returned using an oxygenator. Oxygenator convert
