Text F. Methods Used in Cardiosurgery

In performing the operations on the contracting heart there is danger of the impairment of cardiac function and partial arrest of blood circulation, resulting in the damage to some organs, brain cells in particular.

Such danger is eliminated when artificial blood circulation apparatus called heart-lungs is used during the operation. By using the artificial blood Circulation apparatus the heart is excluded from the blood circulation and the surgeon is able to work on the "dry" heart for a longer period of time achieving better results.

Hypothermia is another method used in heart operations. When the patient is under hypothermia the surgeon can eliminate congenital or developed heart defects without the loss of the patient's blood during the operation.

The method of occlusion consists of bandaging all the vessels carrying blood to and from the heart just before making an incision on the cardiac wall. When the method of occlusion is applied the surgeon evacuates from the heart that amount of blood which is inside its cavities (in the adult it is about 100-150 ml) and performs the necessary operation to eliminate the cardiac defect.

XVI. Choose the answer corresponding to Texts E and F:

1. How is the danger of the partial arrest of blood supply eliminated during heart operations? (a) It is eliminated by using hypothermia; b) It is eliminated by using artificial blood circulation apparatus.) 2. What vessels are bandaged when the method of occlusion is employed in heart operations? (a) The portal veins are bandaged; b) All the vessels carrying blood to and from the heart are bandaged.)
