Optimizing Perioperative Glycemic Control

Best practices for centers of excellence in addressing periprosthetic joint infection

Periprosthetic joint infection is a rare and devastating complication. Management of this complication often requires a multidisciplinary approach similar to that used for the care of patients with cancer. Several studies have reported better outcomes following total joint arthroplasties performed at specialized hospitals than those performed at general hospitals. Specialized institutions use care pathways that aid the multidisciplinary team in decision making. During the recent Musculoskeletal Infection symposium, specific issues were discussed with regard to the treatment of periprosthetic joint infection, including medical optimization, systematic approaches to infection management, and the importance of establishing registries to aid in the creation of Centers of Excellence. A Center of Excellence in periprosthetic infection could provide better overall outcomes with lower financial, physical, and emotional costs to patients.

Perioperative glycemic management in 2011: paradigm shifts

PURPOSE OF REVIEW

The publication of Van den Berghe's landmark study in 2001 supported the use of intensive insulin therapy (IIT) to target normoglycemia in the critically ill and triggered a new era in glycemic management in the perioperative period and in the ICU. In 2009, the normoglycemia in intensive care evaluation-survival using glucose algorithm regulation (NICE-SUGAR) trial demonstrated increased mortality and incidence of hypoglycemia in patients managed with IIT, resulting in a shift toward higher blood glucose targets in this patient population. This review distills clinically pertinent principles from the related literature published in the months since the NICE-SUGAR trial.

RECENT FINDINGS

A target blood glucose level in the acute care setting supported by many of the pertinent societies and frequently quoted in the literature is 140-180 mg/dl. Hyperglycemia, hypoglycemia, and glucose variability are detrimental. Accurate and efficient glucose monitoring devices are essential. Insulin infusion protocols (IIPs) employed to achieve desired blood glucose targets must be individualized and validated for the ICU and institution in which they are being implemented.

SUMMARY

Appropriate glycemic management in the acute care setting can be achieved by targeting a reasonable blood glucose range and employing specific and institutionally validated IIPs.
