why do you need a heart bypass
Before surgery, youБll change into a hospital gown and receive medication, fluids, and anesthesia through an IV. When the anesthesia begins working, youБll fall into a deep, painless sleep. Your surgeon starts by making an incision in the middle of your chest. Your rib cage is then spread apart to expose your heart. Or your surgeon may opt for minimally invasive surgery. This involves smaller cuts and special miniaturized instruments and robotic procedures. You are then hooked up to a cardiopulmonary bypass machine. Also known as the heart-lung machine, it circulates oxygenated blood through your body while your surgeon operates on your heart. Blood is pumped out of your heart by the machine to remove carbon dioxide, and the machine is then filled with oxygen. The oxygenated blood is pumped back into your body without going through the heart and lungs. This keeps oxygenated blood pumping throughout your body. Some procedures are performed Бoff-pump,Б meaning that connecting you to a heart-lung machine isnБt necessary.
Your surgeon will also use cooling techniques, sometimes called extreme cooling, to bring your body temperature down to around 64. 4бF (18бC). This technique suspends your bodyБs processes and makes long heart surgeries possible. Your heart needs less oxygen when your body temperature is lowered. Your doctor cools down your heart with the help of the heart-lung machine or by dousing your heart in cold, salty water. Cooling techniques allow your doctor to operate on your heart tissue for a few hours at a time. These techniques decrease the risk of heart damage or brain damage from a lack of oxygen. Your surgeon then removes a healthy blood vessel from inside your chest wall or leg to replace the blocked or damaged portion of your artery. One end of the graft is attached above the blockage and the other end below. When your surgeon is done, the heart-lung machine is removed, and the function of the bypass is checked. Once the bypass is working, youБll be stitched up, bandaged, and taken to the intensive care unit (ICU) for monitoring.
Taking care of yourself at home immediately after the surgery is an essential part of your recovery.
Incision care is extremely important. Keep your incision site warm and dry, and wash your hands before and after touching it. If your incision is healing properly and there is no drainage, you can take a shower. The shower shouldnБt be more than 10 minutes with warm (not hot) water. You should ensure that the incision site isnБt hit directly by the water. ItБs also important to regularly inspect your incision sites for signs of infection, which include: increased drainage, oozing, or opening from the incision site Pain management is also incredibly important, as it can increase recovery speed and decrease the likelihood of complications like blood clots or. You may feel, pain at incision sites, or pain from chest tubes. Your doctor will likely prescribe pain medication that you can take at home. ItБs important that you take it as prescribed.
Some doctors recommend taking the pain medication both before physical activity and before you sleep. Some patients experience trouble sleeping after open-heart surgery, but itБs important to get as much rest as possible. To get better sleep, you can: avoid, especially in the evenings In the past, some have argued that open-heart surgery leads to a decline in mental functioning. However, most recent research has found that not to be the case. Though some patients may have open-heart surgery and experience mental decline later on, itБs thought that this is most likely. Some people do experience depression or anxiety after open-heart surgery. A therapist or psychologist can help you manage these effects. Most people whoБve had a CABG benefit from participating in a structured, comprehensive rehabilitation program. This is usually done outpatient with visits several times a week. The components to the program include exercise, reducing risk factors, and dealing with, and.
