Abstract
69 A cardiac nurse, Jeanne Zerr, asked a question more than 10 years ago that has helped shape our current knowledge about hyperglycemia in the hospital setting. She wanted to know if high blood glucose levels were associated with increased thoracic wound infections. In 1997, Zerr and her colleagues in Portland, Ore., published an article with the findings that “the incidence of deep wound infection in diabetic patients was reduced after implementation of a protocol to maintain mean blood glucose levels < 200 mg/dl in the immediate postoperative care.” 1 Once the Portland group identified that hyperglycemia did affect wound healing, they developed a protocol to administer IV insulin to achieve tighter glucose control intraopertively and postoperatively. 2 They have continued to study the impact of hyperglycemia
