Summary

Male sex and pulmonary disease independently predict sternal wound infections after cardiac surgery. Identifying these risk factors helps target prophylactic measures to reduce infection rates and improve patient outcomes.

Area of Science:

  • Cardiology
  • Thoracic Surgery
  • Infectious Disease

Background:

  • Sternal wound infection and dehiscence are serious complications following sternotomy.
  • These complications are associated with significant morbidity and mortality.

Purpose of the Study:

  • To identify independent risk factors for major sternal wound infection and dehiscence after sternotomy.
  • To inform targeted prophylactic strategies for high-risk patients.

Main Methods:

  • Retrospective case-control study analyzing 31 patients with sternal wound infection/dehiscence and a control group of 1,521 patients.
  • Data collected included patient demographics, comorbidities, and perioperative variables.
  • Statistical analysis identified significant predictors of sternal complications.

Main Results:

  • The overall sternal infection rate was 2.1%, with a 16.2% mortality rate in affected patients.
  • Independent predictors of sternal wound infection were male sex and pulmonary disease (e.g., chronic obstructive pulmonary disease).
  • Other factors like prolonged ICU stay, respiratory failure, and connective tissue disease were also associated with higher infection rates.

Conclusions:

  • Male sex and pulmonary disease are significant, independent risk factors for sternal wound infection post-sternotomy.
  • Identifying patients with these risk factors is crucial for implementing enhanced prophylactic measures.
  • Further research may explore the interplay of various risk factors to optimize patient care.
