Almost two centuries after anesthetics revolutionized surgery, a growing body of research is pointing to disturbing side effects that range from delirium to cancer-proliferating immune suppression. Researchers knocked out the sheep last month at the University of Melbourne to try to understand why common open-heart procedures lead to acute kidney injury in up to a third of patients — part of a broader effort to study the impact of anesthesia on the immune system, brain and other major organs.
