Recently, heart surgery of all kinds has become possible, especially in the middle of the twentieth century. The most important contribution of scientific technology is the great discovery of the heart and lung machine.
The way it works is to turn the blood circulation to its proper course in the heart. The heart and lung machine is limited by the blood supply and saturated oxygen required to complete this process. In addition, there has been a significant development in the drugs that inhibit oxidation, immunity, and rejection of foreign objects. The ability to lower the temperature during the operation.
At present, many cardiac operations are performed, such as valve replacement, heart replacement, artificial heart transplantation and transfer from another person, or cardiac organ transplantation, such as artificial heart transplantation, as well as surgery on large arteries such as aortic arteries, which cause the fuse of the valves, or blood vessels to narrow.
Cardiothoracic surgery is an operation performed by people who specialize in heart disease or so-called heart surgeons. In general, heart surgery involves two main sections: closed-heart surgery and open-neck surgery.
Heart surgery is an example of chest surgery. Of the closed and open heart in the classification type, which is attributed to the industrial heart and lung machine on the one hand. Open heart process if the symptoms are called for an open heart operation, the procedure should be performed immediately. Blood is donated before the operation by the donors. The doctor is advised not to take aspirin for at least 10 days. To give anticoagulant to the patient before the time of the operation, and if there are any signs of respiratory symptoms, infection and chills should be informed by the doctor immediately before the operation, if found a week before the operation.
If the patient is admitted to the intensive care unit, the efficiency of the heart must be determined by inserting a catheter across the vein in the neck along the right atrium and the right ventricle at the same time and the pulmonary artery.
It measures the blood pressure and the pressure of the heart chambers and monitors the amount of blood passing through the heart, ECG is monitored, and some patients may experience several changes in the heart after an open heart operation.
