Why is the body temperature of the patient lowered?
The body temperature is decreased to 27 degrees Centigrade. Cooling helps preserve the body tissues and the heart muscle during the physiologic alterations characteristic of heart-lung bypass and open heart surgery. It also reduces the oxygen debt requirements of the body while connected to the heart-lung machine. 4.3. How long does it take to know whether the operation was successful? In most Ross Procedures, the result can be immediately assessed in the operating room using transesophageal echocardiography. The presence of leakage, blockage, kinking, or other possible distortions of the implanted autograft (or even cadaver pulmonary replacement) can be visualized, and appropriate steps taken if necessary. Once the physiology and anatomy of the result has been confirmed and the patient stabilized, the incision is closed and the patient returned to the intensive care unit. 4.4.
