Does glycine add to the beneficial effects of perioperative oral immune-enhancing nutrition supplements in high-risk cardiac surgery patients?
Preoperative OIENS reduces postoperative infectious morbidity and results in a more stable circulation; the addition of glycine does not result in any beneficial effect over standard OIENS.
Most SDMs of chronically critically ill patients will not have the benefit of knowing the patient's preferences for life-sustaining therapies and consequently be at risk of increased decisional burden.
