heart-surgery

Open heart surgery is a general name given to heart surgery performed by correcting the heart diseases by excluding the heart and lungs.


The patient is heparinized, venous blood is collected from a suitable place, collected by filtration into a chamber, oxygenated by means of a pump, pumped into any of the arteries or aorta by partially excreting CO2.


When the procedure is performed, the temperature required by the patient's surgery is decreased (up to 18 degrees) and the patient is reheated when the procedure related to the heart is finished.


This process in which body blood is directed through the machine is called EXTRACORPOREAL CIRCULATION (ECC = extracorporeal circulation) or CARDIOPULMONARY BYPASS (CPB = pass through the heart and lung). Fr. It has been used in our language as “cardiopulmonary bypass Okun.


Accordingly, the name of the machine used in ECC or CPB is “heart-lung pump”.


Components of the heart lung pump:


1- Arterial and venous lines

2- Reservoir (where the venous blood is stored)

3- Pump (venous blood and arterial line is a device that can give pressure.

A-Roller Pump-Rotating line compression through pumping-pump type

b- Centrifugal pump - capable of pumping blood by centrifugal force when rotated through pallets.

c- Diaphragm type pump is available in the room where the diaphragm is moved back and forth.


The cheapest and most widely used roller pump among these types of pumps.


4- Oxygenator (consisting of fibers that provide O2 input to the blood and CO2 output from the blood)

5- Mixer (is the device which sends the air / O2 ratio to the blood by adjusting the desired ratio to the oxygenator)

6- The heat exchanger is usually outside the oxygenator; circulates the heated or cooled water around the oxygenator, allowing the blood to warm / cool.

7- Suction lines: During the surgery, the blood that is bleeding around or the blood collected in the heart-vessels are absorbed and sent to the reservoir. Because they are connected to the pump assembly, they suck the blood with the negative pressure they create through “suction ve or“ aspiration ve and pump it into the chamber. The apparatus that performs the operation is called “sucker”.

a- Coronary suction: It is used to collect the blood collected into the cavities around the chamber. Coronary aspirator used on the operating table is called “coronary sucker..

b- It is used to improve surgical vision due to blood coming from the ascending aorta, left atrium, pulmonary artery and coronary sinus. This process is called “VENTING.. The end of the procedure is called İşlem venting catheter ”or“ vent aca.

8- Cardioplegia pump or pumps. They are used to pump blood to the heart during the procedure.

Figure (photo): Intraoperative view of the heart-lung machine and chamber. There are taps and lines on the reservoir where the medicines that should be given while the patient is on ECC can be made. A thick line penetrates into the reservoir in the middle; there is a heat probe on it (main venous line), the sucker and the lines coming from the vents are also connected to the chamber, all collected through a filter. Although all these links seem very complicated, karışık The system is actually simple enough to be summarized as follows.
