The elderly are the fastest growing segment of the population and undergo 25-30% of all surgical procedures. Postoperative cognitive problems are common in older patients following major surgery. The socioeconomic implications of these cognitive disorders are profound; cognitive decline is associated with a loss of independence, a reduction in the quality of life, and death. This review will focus on the two most common cognitive problems following surgery: postoperative delirium and postoperative cognitive dysfunction (POCD). ⋯ The etiology of postoperative cognitive problems is unknown, but there is emerging evidence that decreased preoperative cognitive function contributes to the development of postoperative delirium and POCD. There is growing concern that inhalation anesthetics may be neurotoxic to the aging brain, but there are no human data evaluating this hypothesis to date. Randomized controlled trials evaluating interventions to improve long-term cognitive outcomes in elderly patients are urgently needed.

ReviewAcute pain management of patients with multiple fractured ribs: a focus on regional techniques.
Thoracic trauma leading to multiple fractured ribs (MFR) remains very common. Good analgesia may help to improve a patient's respiratory mechanics and to avoid intubation of the trachea for ventilatory support and therefore may dramatically alter the course of recovery. We herein review the analgesia options for patients with MFR. ⋯ Thoracic epidural, thoracic paravertebral, and intercostal blocks are the top choices for patients with MFR and they are of equivalent efficacy. Each has unique advantages and disadvantages. Our preference tends to be the thoracic paravertebral approach.

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. ⋯ 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.

Postoperative sepsis is a major cause of surgical associated morbidity and mortality. Our goal is to describe its incidence, pathophysiology, and contributing factors. In addition, we will review preventive measures and treatment options that may possibly reduce its healthcare burden. ⋯ The incidence of postoperative sepsis has not declined over the past years, although mortality is trending downwards. Several biochemical and genetic markers may allow early diagnosis. Prevention and prompt treatment may lower mortality.
