I didn't mean to imply that doctors don't care about their patients. Many are just not fully informed about the risks and complications of blood transfusions, nor about the alternatives. As you say, they genuinely believe they are doing what's best for their patients, because that's what they have been taught. But now that the word is out that stored blood may do more harm than good, will they stop using it until the new process for putting nitric oxide back into blood goes through the necessary clinical trials and gets approval?
