Heart bypass surgery is performed to make a new path for the flow of blood and oxygen to the heart. It is performed when coronary artery disease partly or completely blocks the arteries the blood vessels which supply the heart with oxygen and nutrients – that lead into the heart.
Before receiving surgery the Patients receive anesthesia, which renders them unable to feel the pain. The anesthesia effects last for the whole time of the operation. The majority of the men and women who have bypass surgery are linked to a bypass pump or a heart-lung bypass machine that does the work of the heart while the heart is stopped during operation. The machine circulates the blood and adds oxygen to it. Another technique of operation does not use the machine but instead allows the bypass to be created while the heart remains beating.
Once the patients are the surgeon cuts an incision 10 inches long at the middle of the chest. Afterward, the breastbone is split to allow the surgeon to find the heart and aorta. The valve replacement singapore surgeon will take an artery or vein from another part of the patients’ bodies and use it to make a graft around the artery’s obstructed area. Often the saphenous vein in the leg is used – an incision is made along the inside of the leg between the groin and ankle to reduce the vein, which is then sewn to the coronary artery on one side and to an opening at the aorta on the other.
Sometimes the internal mammary artery in the chest is used for grafting; this has the benefit that one end of the artery is already connected to the aorta, so only the other end has to be sewn to the coronary artery. After the graft is completed, the patients’ breastbone is reconnected with a cord and the incision is closed. There might also be a flexible tube called a catheter in the bladder to drain the urine; and intravenous lines for fluid ingestion. Monitors constantly provide information concerning the patients’ vital signs like breathing, temperature, and pulse. Generally the patients leave the IC unit within a day, and are transferred to a normal care unit to recoup their strength. Normally patients spend about a week at the hospital; and it takes four to six weeks for the patients to start feeling better.
