What effect do glucose levels greater than 150 mg/dl within the first 24 hours post-op have on infection rates?

Reduce infection rates by 5%
Increase infection rates by 4%
Increase infection rates by 8%
No impact on infection rates

The correct answer is: Increase infection rates by 8%

Glucose levels greater than 150 mg/dl within the first 24 hours post-operative are associated with an increased risk of infection. Elevated blood glucose can impair immune function, particularly affecting white blood cell activity. This weakened immune response compromises the body’s ability to fight off pathogens, making individuals more susceptible to infections. Research has shown that hyperglycemia in the immediate post-operative period correlates with a heightened rate of surgical site infections and other related complications. An increase in infection rates by 8% under these conditions reflects the negative impact that elevated glucose levels can have on a patient’s recovery and overall health outcomes. Maintaining glucose levels within normal ranges is crucial for minimizing the risk of infections and ensuring better surgical recovery.
