I am having open heart surgery on Monday July 7th. I am one of Jehovah's witnesses and plan on using the cell saver machine and also the heart, lung machine as I want a bloodless surgery. I need to know does the doctor automatically use salene to prime the machines? Do I need to make sure what he plans to do as far as fluids running in the machine with my blood? I won't be able to talk to the doctor until the morning of my surgery.
