Summary

The PATCH pilot trial aims to establish feasibility and determine the sample size of a future, large-scale, multi-site RCT, as well as reinforce the long-standing known safety profile of glucose, insulin, and potassium (GIK) and explore the physiologic response. We hypothesize that the use of GIK in non-diabetic patients undergoing abdominal surgery, will reduce rates of morbidity \& death compared to standard of care treatment. In brief, primary outcomes of interest include estimation of the standard deviation (to derive a sample size estimation) and the ability to recruit target population, assessment of patient compliance/burden, and assessment of provider compliance/burden (feasibility).

Detailed description

Elevated glucose levels during surgery are common and dramatically increase the risk of morbidity and mortality. This has been identified in multiple statewide quality improvement collaboratives, with a monotonic relationship between increased glucose levels and higher risks of almost all adverse events. While perioperative glucose management tends to focus on those with diabetes, some degree of perioperative hyperglycemia occurs in as much as two thirds of non-diabetic patients. A recently identified phenomenon is that, at the same levels of hyperglycemia, non-diabetic patients have a much greater risk of death and complications compared to patients with diabetes. Given that hyperglycemia is typically considered a problem for people with diabetes, this finding has been described as a hyperglycemia paradox. Unfortunately, treatment with insulin can only happen after hyperglycemia has been recognized, and since non-diabetic patients are often not monitored for hyperglycemia, hyperglycemia is likely to be under-recognized. Moreover, addressing hyperglycemia after the fact may not be as effective in reducing adverse events as preventing hyperglycemia. There is a long history of using perioperative insulin in patients undergoing at least one type of surgery. For over 45 years cardiac anesthesiologists have been testing the benefits of insulin combined with glucose and potassium (GIK) in cardiac surgery. In more than 30 RCTs, including more than 2000 patients with and without diabetes, GIK prophylaxis has been shown to be safe, with \< 1 in 200 participants experiencing hypoglycemia secondary to the inclusion of glucose in the formulation. Moreover, these studies have found large reductions in surgically induced inflammation and often significant improvements in clinical outcomes.
