Description
Technical Field
The invention relates to the field of medical instruments, in particular to a vena cava retrograde perfusion tube and a use method thereof.
Background
Extracorporeal circulation is a technique of temporarily replacing the human heart and lungs with a special device to perform blood circulation and gas exchange. Such devices are referred to as artificial hearts (pumps) and artificial lungs (oxygenators), also known collectively as artificial heart-lungs, artificial heart-lung devices, or extracorporeal circulation devices. During extracorporeal circulation, venous blood is led into the blood storage tank through the superior vena cava cannula and the inferior vena cava cannula, the artificial heart (pump) pumps the venous blood into the artificial lung for oxygenation and discharges carbon dioxide, and the oxygenated blood is pumped into an internal artery system through the artificial heart under certain pressure, so that the silence and clear operation field during operation are ensured, the blood supply of other important organs except the heart is also ensured, and the blood storage tank is an important guarantee measure for the development of great cardiac vessel surgery.
Currently, in total aortic arch replacement, "deep hypothermia-arrest-cycle selective brain perfusion (ACP + DHCA)" techniques are commonly used. However, this technique is performed with complete ischemia of the lower body, low temperature and long extracorporeal circulation, which all cause severe organ damage and coagulation dysfunction, and therefore these patients are typically characterized by a height of 4: i.e., high mortality, high incidence of organ dysfunction, high blood transfusion rate, and high blood volume transfusion.
The continuous maintenance of systemic perfusion is critical to improve the adverse effects of ACP + DHCA on patients. Therefore, when the selective cerebral perfusion is combined with the inferior vena cava intubation retrograde perfusion (ACP + RIVP) to replace ACP + DHCA in the total aortic arch replacement surgery, the whole body blood perfusion can be continuously maintained, so that the lower half body has no ischemia time, and the patient does not need deep hypothermia any more. These changes would avoid damage to the body from cryogenic arrest and improve patient prognosis.
However, the existing extracorporeal circulation device can only implement deep hypothermia arrest circulation selective cerebral perfusion (ACP + DHCA) and cannot implement selective cerebral perfusion combined with inferior vena cava retrograde perfusion (ACP + RIVP), and a product directly used for the ACP + RIVP is urgently needed. Shorten the preparation time, shorten the operation time and improve the prognosis of patients.
