During the early 1960s, American heart surgeon Denton Cooley successfully performed numerous bloodless open-heart surgeries on Jehovah's Witness patients. Fifteen years later, he and his associate published a report of more than 500 cardiac surgeries in this population, documenting that cardiac surgery could be safely performed without blood transfusion.
[11] [12] This research was motivated by a desire to stop the heart from beating long enough to do surgery on the heart while it remained still. Since heart-lung machines, also known as cardiopulmonary bypass (CPB), had not been invented yet, stopping the heart meant stopping blood circulation to the whole body, including the brain.
Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the circulation of blood and oxygen throughout the body. [1] As such it is an extracorporeal device. CPB is operated by a perfusionist. The ...
Blood donation centers signed on to a plan in which they provide blood to rescue services, and if it goes unused for two weeks, the blood can be returned. If it is deemed safe after testing, then ...
The technique uses devices to support the surrounding heart tissues while vital surgery takes place. This is also known as off-pump CABG (OPCAB). OPCAB voids the use of cardiopulmonary bypass (CPB), which requires the heart to be stopped (arrested) with cardioplegia solution. Off-pump is also known as beating heart surgery. [citation needed]
O. H. "Bud" Frazier is a heart surgeon and director of cardiovascular surgery research at the Texas Heart Institute (THI), best known for his work in mechanical circulatory support (MCS) of failing hearts using left ventricular assist devices (LVAD) and total artificial hearts (TAH).
The procedure is frequently used in cardiothoracic and vascular surgery, during which blood usage has traditionally been high. A greater effort to avoid adverse events due to transfusion has also increased the emphasis on blood conservation (see bloodless surgery ).
She previously had heart surgery. In 2023, Jean revealed in an Instagram post that she had recently had heart surgery. During that same year, she also had an appendectomy, per People .
