Which of the following is true regarding the risk factors for surgical site infections in cardiac surgeries?

Diabetes and obesity are indeed significant risk factors for surgical site infections in cardiac surgeries. Both conditions can compromise the immune system and lead to poorer wound healing, which increases the susceptibility to infections. Diabetic patients often have altered immune responses, and impaired circulation due to obesity can hinder proper healing after surgery.

Other patient-related factors, such as age and comorbid conditions, also play a role, but the prominence of diabetes and obesity in the context of cardiac surgery highlights the importance of managing these conditions preoperatively to minimize infection risks.

While surgical factors such as the type of procedure and duration can influence the risk of infection, diabetes and obesity are particularly impactful due to their widespread prevalence and the physiological changes they impose on the body.
